Page 4 Important regulatory information The 450 Platform Family products are certified as an unlicensed device in frequency bands where it is not allowed to cause interference to licensed services (called primary users of the bands). Application software Download the latest 450 Platform Family software and install it in the Outdoor Units (ODUs) before deploying the equipment. Instructions for installing software are provided in Upgrading the software version and using CNUT on page 7-64. USA specific information Caution This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:  This device may not cause harmful interference, and  This device must accept any interference received, including interference that may cause undesired operation The USA Federal Communications Commission (FCC) requires manufacturers to implement special features to prevent interference to weather radar systems that operate in the band 5600 MHz to 5650 MHz. These features must be implemented in all products able to operate outdoors in the band 5470 MHz to 5725 MHz. Manufacturers must ensure that such radio products cannot be configured to operate outside of FCC rules; specifically it must not be possible to disable or modify the radar protection functions that have been demonstrated to the FCC. Cambium supplies variants of the 450i and 450m Series specifically for operation in the USA in order to comply with FCC requirements (KDB 905462 D02 UNII DFS Compliance Procedures New Rules v01r02). These variants are only allowed to operate with license keys that comply with FCC rules. Similarly, Cambium supplies variants of the 450 Series specifically for operation in the USA in order to comply with FCC requirements (KDB 443999 D01 Approval of DFS UNII Devices v01r04). These variants are only allowed to operate with license keys that comply with FCC rules. To ensure compliance when using PMP 450 Series and PTP 450 Series, follow the recommendation in Avoidance of weather radars (USA only).

Page 5 External antennas When using a connectorized version of the product, the conducted transmit power may need to be reduced to ensure the regulatory limit on transmitter EIRP is not exceeded. The installer must have an understanding of how to compute the effective antenna gain from the actual antenna gain and the feeder cable losses. The range of permissible values for maximum antenna gain and feeder cable losses are included in this user guide together with a sample calculation. The product GUI automatically applies the correct conducted power limit to ensure that it is not possible for the installation to exceed the EIRP limit, when the appropriate values for antenna gain and feeder cable losses are entered into the GUI. Avoidance of weather radars (USA only) To comply with FCC rules (KDB 443999: Interim Plans to Approve UNII Devices Operating in the 5470 - 5725 MHz Band with Radar Detection and DFS Capabilities), units which are installed within 35 km (22 miles) of a Terminal Doppler Weather Radar (TDWR) system (or have a line of sight propagation path to such a system) must be configured to avoid any frequency within +30 MHz or –30 MHz of the frequency of the TDWR device. This requirement applies even if the master is outside the 35 km (22 miles) radius but communicates with outdoor clients which may be within the 35 km (22 miles) radius of the TDWRs. If interference is not eliminated, a distance limitation based on line-of-sight from TDWR will need to be used. Devices with bandwidths greater than 20 MHz may require greater frequency separation. When planning a link in the USA, visit http://spectrumbridge.com/udia/home.aspx, enter the location of the planned link and search for TDWR radars. If a TDWR system is located within 35 km (22 miles) or has line of sight propagation to the PTP device, perform the following tasks:  Register the installation on http://spectrumbridge.com/udia/home.aspx.  Make a list of channel center frequencies that must be barred, that is, those falling within +30 MHz or –30 MHz of the frequency of the TDWR radars. The 450 Platform Family AP must be configured to not operate on the affected channels. Canada specific information Caution This device complies with ISEDC ’s license-exempt RSSs. Operation is subject to the following two conditions: (1) This device may not cause interference; and (2) This device must accept any interference, including interference that may cause undesired operation of the device. ISEDC requires manufacturers to implement special features to prevent interference to weather radar systems that operate in the band 5600 MHz to 5650 MHz. These features must be implemented in all products able to operate outdoors in the band 5470 MHz to 5725 MHz.

Page 6 Manufacturers must ensure that such radio products cannot be configured to operate outside of ISEDC rules; specifically it must not be possible to disable or modify the radar protection functions that have been demonstrated to ISEDC . In order to comply with these ISEDC requirements, Cambium supplies variants of the 450 Platform Family for operation in Canada. These variants are only allowed to operate with license keys that comply with ISEDC rules. In particular, operation of radio channels overlapping the band 5600 MHz to 5650 MHz is not allowed and these channels are permanently barred. In addition, other channels may also need to be barred when operating close to weather radar installations. Other variants of the 450 Platform Family are available for use in the rest of the world, but these variants are not supplied to Canada except under strict controls, when they are needed for export and deployment outside Canada.

Chapter 1: Product description Wireless operation Page 1-16 Wireless operation This section describes how the 450 Platform Family wireless link is operated, including modulation modes, power control and security. Time division duplexing The system uses Time Division Duplexing (TDD) – one channel alternately transmits and receives rather than using one channel for transmitting and a second channel for receiving. To accomplish TDD, the AP/BHM must provide sync to its SM/BHS. Furthermore, collocated APs/BHMs must be synced together – an unsynchronized AP/BHM that transmits during the receive cycle of a collocated AP/BHM can prevent a second AP/BHM from being able to decode the signals from its APs/BHSs. In addition, across a geographical area, APs/BHMs that can “hear” each other benefit from using a common sync to further reduce self-interference within the network. Modules use TDD on a common frequency to divide frames for uplink (orange) and downlink (green) usage, as shown in the figure below. For more information on synchronization configuration options, see GPS synchronization on page 2-45. Figure 2 TDD frame division Time

Chapter 1: Product description Wireless operation Page 1-17 TDD frame parameters The TDD burst duration varies depending on the following:  Channel Bandwidth  Cyclic Prefix  Frame Period  Frame configuration - Downlink Data  Link operation – Dynamic Rate Adaptation OFDM and channel bandwidth The PMP/PTP 450 Platform Family transmits using Orthogonal Frequency Division Multiplexing (OFDM). This wideband signal consists of many equally spaced sub-carriers. Although each sub carrier is modulated at a low rate using conventional modulation schemes, the resultant data rate from the sub-carriers is high. OFDM works exceptionally over a Non-Line-of-Sight (NLoS) channel. The channel bandwidth of the OFDM signal is configurable to one of the following values: 5, 7, 10, 15, 20 and 30 MHz. Higher bandwidths provide greater link capacity at the expense of using more bandwidth. Systems configured for a narrower channel bandwidth provide better receiver sensitivity and can also be an appropriate choice in deployments where the amount of free spectrum is limited. Note The channel bandwidth must be configured to the same value at both ends of the link. Not all channel bandwidths are available in all regulatory bands. Cyclic Prefix OFDM technology uses a cyclic prefix, where a portion of the end of a symbol (slot) is repeated at the beginning of the symbol (slot) to allow multi-pathing to settle before receiving the desired data. A 1/16 cyclic prefix means that for every 16 bits of throughput data transmitted, an additional bit is used. For your convenience, the 450 Platform Family ODUs have been locked to a 1/16 CP. Frame Period The frame period or frame duration is the time between the beginning of a frame and the end of the frame. The 450 Platform Family supports two frame periods: 2.5 ms and 5 ms. Note PMP 450m AP supports 2.5 ms Frame Period only. The 5ms frame period configuration provides higher throughput as a result of reduced frame overhead during transmission. In turn, the 2.5 ms frame period configuration affords reduced latency in the system, half of that introduced by the 5 ms frame configuration.

Chapter 1: Product description Wireless operation Page 1-18 Frame configuration - Downlink Data The percentage of frame assigned to transport downlink data. The downlink data specifies the percentage of the aggregate throughput for the downlink (frames transmitted from the AP/BHM to the subscriber). The configurable range is 15% to 85%. Note The maximum configurable range is 34% to 66% for 40 MHz with 5 ms frame. Link operation – Dynamic Rate Adapt The 450 Platform Family ODUs offer eight levels or speeds of operation – 2X MIMO-B and 1X MIMO-A (QPSK), 4X MIMO-B and 2X MIMO-A (16-QAM), 6x MIMO-B and 3X MIMO-A (64-QAM) and 8X MIMO-B and 4X MIMO-A (265-QAM). If received power varies due to distance between the AP/BHM and the SM/BHS or due to obstructions, or if interference affects the RF environment, the system automatically and dynamically adjusts the links to the best operation level. The system chooses its modulation rate dynamically, based on an internal ARQ (Automatic Repeat reQuest) error control method. With ARQ, every data slot of every frame sent over the air (except downlink broadcast) is expected to be acknowledged by the receiver, and if acknowledgement is not received, the data is resent. The sending unit monitors these re-sends and adjusts the modulation rate accordingly. It is normal to have links that change levels of operation as the RF environment changes. Furthermore, the uplink or downlink portions of TDD duty cycle operate independently. The various modulation levels used by 450 Platform Family are shown in Table 11. Table 11 Modulation levels Rate MIMO-B MIMO-A QPSK 2X MIMO-B 1X MIMO-A 16-QAM 4X MIMO-B 2X MIMO-A 64-QAM 6X MIMO-B 3X MIMO-A 256-QAM 8X MIMO-B 4X MIMO-A Note MIMO-A achieves half the throughput of MIMO-B but adds a combining diversity (gain) which enhances the link budget or availability.

Chapter 1: Product description Wireless operation Page 1-19 Encryption The 450 Platform Family supports optional encryption for data transmitted over the wireless link. The 450 Platform Family supports the following forms of encryption for security of the wireless link:  DES (Data Encryption Standard): An over-the-air link encryption option that uses secret 56-bit keys and 8 parity bits. DES performs a series of bit permutations, substitutions, and recombination operations on blocks of data. DES encryption does not affect the performance or throughput of the system.  AES (Advanced Encryption Standard): An over-the-air link encryption option that uses the Rijndael algorithm and 128-bit keys and 256-bit key size to establish a higher level of security than DES. AES products are certified as compliant with the Federal Information Processing Standards (FIPS 197) in the U.S.A. The default setting on an AP is "Disabled". MIMO Multiple-Input Multiple-Output (MIMO) techniques provide protection against fading and increase the probability that the receiver decodes a usable signal. When the effects of MIMO are combined with those of OFDM techniques and a high link budget, there is a high probability of a robust connection over a non-line-of-sight path. The sub-features that comprises the MIMO techniques utilized in the 450 Platform Family ODUs are:  MIMO-A: This technique enables 450 Platform Family radio to use a scheme that optimizes coverage by transmitting the same data over both antennas. This redundancy improves the signal to noise ratio at the receiver making it more robust.  MIMO-B: This technique provides the ability to double the throughput of a radio transmission under proper RF conditions. Different data streams are transmitted simultaneously on two different antennas. MU-MIMO Multiple-input multiple-output, or MIMO, is a range of technologies used to multiply the capacity of a wireless connection without requiring more spectrum. Although traditional MIMO techniques are focused on increasing the bandwidth available between two wireless nodes, multi-user MIMO (MU-MIMO) applies these technologies to increase overall wireless network capacity by allowing an access point to communicate wirelessly with more than one wireless node at once. A MU-MIMO access point features an array of antennas. When the AP decides to communicate with multiple nodes at the same time, it creates multiple simultaneous beams each directed to a specific node. This is contrast to a traditional wireless system, where two wireless nodes cannot communicate on the same channel to the same access point at the same time, without causing significant self-interference and degrading the overall wireless network performance.

Chapter 1: Product description Wireless operation Page 1-20 A MU-MIMO access point estimates and measures what a transmission from each wireless node ‘sounds like’, by applying knowledge of the wireless path characteristics between the access point and node. Known as channel estimation, this process is of vital importance; without it, the access point cannot distinguish properly between wireless nodes, affecting performance. Channel estimation is achieved by the access point sending a specific signal to a wireless node, which the node then reflects back. By measuring how the signal was received back from the node, the access point can estimate the wireless conditions between itself and the node, and know to expect these same conditions to be applied to other communications from that node. This is known as channel sounding. Channel estimation and sounding must be regularly repeated to ensure wireless network performance remains high; the speed at which a system is able to accurately estimate the channel has a large impact on performance. Once channel estimation is completed for a wireless node, the MU-MIMO access point can electrically tune each antenna to provide the highest performance for that node. The access point uses beamforming to create a radio beam to that node which is tuned for optimum performance and avoids beams directed to other nodes, reducing interference and helping to improve overall wireless network capacity. A MU-MIMO access point can communicate to multiple wireless nodes simultaneously using this process. As the majority of nodes are unable to make full use of the whole access point capacity at once, communicating with several nodes simultaneously can greatly improve the overall capacity achieved in the wireless network. .

Chapter 1: Product description System management Page 1-21 System management This section introduces the 450 Platform Family management system, including the web interface, installation, configuration, alerts and upgrades. Management agent The 450 Platform Family radios are managed through an embedded management agent. Management workstations, network management systems or PCs can be connected to this agent using the module’s Ethernet port or over-the air (SM/BHS) The management agent supports the following interfaces:  Hypertext transfer protocol (HTTP)  Hypertext transfer protocol secure (HTTPS)  RADIUS authentication  Simple network management protocol (SNMP) – v2c and v3  Network time protocol (NTP)  System logging (Syslog)  Wireless Manager (WM) software  Canopy Network Updater Tool (CNUT) software  cnMaestro™ Web server The 450 Platform Family management agent contains a web server. The web server supports access via the HTTP/HTTPS interface. Web-based management offers a convenient way to manage the 450 Platform Family radios from a locally connected computer or from a network management workstation connected through a management network, without requiring any special management software. The web and SNMP are the interfaces supported for installation of 450 Platform Family radios and for the majority of configuration management tasks.

Chapter 1: Product description System management Page 1-22 Web pages The web-based management interfaces provide comprehensive web-based fault, configuration, performance and security management functions organized into the following groups: Access Point or Backhaul Master:  Home  Configuration  Statistics  Tools  Logs  Accounts  Quick Start  Copyright Subscriber Module or Backhaul Slave  Home  Configuration  Statistics  Tools  Logs  Accounts  PDA  Copyright Identity-based user accounts  When identity-based user accounts are configured, a security officer can define from one to four user accounts, each of which may have one of the four possible roles:  ADMINISTRATOR, who has full read and write permissions. This is the level of the root and admin users, as well as any other administrator accounts that one of them creates.  INSTALLER, who has permissions identical to those of ADMINISTRATOR except that the installer cannot add or delete users or change the password of any other user.  TECHNICIAN, who has permissions to modify basic radio parameters and view informational web pages  GUEST, who has no write permissions and only a limited view of General Status tab  Admin, Installer and Tech accounts can be configured as READ-ONLY. This will allow the account to only see the items. See Managing module access by passwords for detailed information on account permissions.

Chapter 1: Product description System management Page 1-23 Remote Authentication Dial-in User Service (RADIUS) The PMP configuration of 450 Platform Family includes support for RADIUS (Remote Authentication Dial In User Service) protocol functionality including:  SM Authentication: Allows only known SMs onto the network (blocking “rogue” SMs), and can be configured to ensure SMs are connecting to a known network (preventing SMs from connecting to “rogue” APs). RADIUS authentication is used for SMs, but not used for APs.  SM Configuration: Configures authenticated SMs with MIR (Maximum Information Rate), High Priority, and VLAN (Virtual LAN) parameters from the RADIUS server when a SM registers to an AP.  User Authentication allows users to configure a separate User authentication server along with the SM authentication server. If firmware is upgraded while using this functionality and no User authentication servers are configured, then AP continues to use the SM authentication server for User authentication  SM Accounting provides support for RADIUS accounting messages for usage-based billing. This accounting includes indications for subscriber session establishment, subscriber session disconnection, and bandwidth usage per session for each SM that connects to the AP.  Centralized AP and SM user name and password management: Allows AP and SM usernames and access levels (Administrator, Installer, Technician and Read-Only) to be centrally administered in the RADIUS server instead of on each radio and tracks access events (logon/logoff) for each username on the RADIUS server. This accounting does not track and report specific configuration actions performed on radios or pull statistics such as bit counts from the radios. Such functions require an Element Management System (EMS) such as Cambium Wireless Manager. This accounting is not the ability to perform accounting functions on the subscriber/end user/customer account.  Framed-IP-Address: Operators may use a RADIUS server to assign management IP addressing to SM modules. SNMP The management agent supports fault and performance management by means of an SNMP interface. The management agent is compatible with SNMP v2c and SNMP v3 using Management Information Base (MIB) files which are available for download from the Cambium Networks Support website: https://support.cambiumnetworks.com/files/ptp450 https://support.cambiumnetworks.com/files/pmp450 Network Time Protocol (NTP) The clock supplies accurate date and time information to the system. It can be set to run with or without a connection to a network time server (NTP). It can be configured to display local time by setting the time zone and daylight saving in the Time web page. If an NTP server connection is available, the clock can be set to synchronize with the server time at regular intervals. The 450 Platform Family radios may receive NTP data from a CMM4 module or an NTP server configured in the system’s management network.

Chapter 1: Product description System management Page 1-24 The Time Zone option is configurable on the AP’s/BHM’s Time Configuration page, and may be used to offset the received NTP time to match the operator’s local time zone. When set on the AP/BHM, the offset is set for the entire sector (AP/BHSs is notified of the current Time Zone upon initial registration). If a Time Zone change is applied, the AP/BHSs are notified of the change in a best effort fashion, meaning some AP/BHSs may not pick up the change until the next re-registration. Time Zone changes are noted in the Event Log. An AP/BHM which is receiving NTP date and time information from an NTP server or from a GPS synchronization source may be used as an NTP server. Any client which has IP connectivity to the BHM may request NTP date and time information from the AP/BHM. No additional configuration (other than the AP/BHM receiving valid NTP data) is required to use the AP/BHM as an NTP server.

Chapter 2: System hardware Cabling Page 2-34 Outdoor copper Cat5e Ethernet cable Outdoor Cat5e cable is used for all connections that terminate outside the building. For example, connections between the ODU, surge suppressors (if installed), UGPS receivers (if installed) and the power supply injector. This is known as a “drop cable” (Figure 21). The following practices are essential to the reliability and longevity of cabled connections:  Use only shielded cables and connectors to resist interference and corrosion.  For vertical runs, provide cable support and strain relief.  Include a 2 ft (0.6 m) service loop on each end of the cable to allow for thermal expansion and contraction and to facilitate terminating the cable again when needed.  Include a drip loop to shed water so that most of the water does not reach the connector at the device.  Properly crimp all connectors.  Use dielectric grease on all connectors to resist corrosion. Order Superior Essex type BBDGe cable from Cambium Networks (Table 39). Other lengths of this cable are available from Superior Essex.

Chapter 2: System hardware GPS synchronization Page 2-45 GPS synchronization GPS synchronization description Cambium offers GPS synchronization to limit the network’s own self-interference. The Cluster Management CMM provides Global Positioning System (GPS) synchronization to the Access Point (AP) and all associated Subscriber Modules (SM). Network operators have a choice of UGPS and CMM solutions to select the option that works best for the environment. Universal GPS (UGPS) The UGPS provides network synchronization for smaller networks where a CMM may not be cost effective. The UGPS provides synchronization for one or two modules so that even remote areas at the edge of the network can operate with synchronization for improved performance. The UGPS works with all Cambium PMP radios. The UGPS has a small footprint and is easy to deploy. Figure 28 UGPS Note PMP 450/450i/450m Series - APs can power up a UGPS via the Aux/Timing port.

Chapter 2: System hardware GPS synchronization Page 2-46 CMM5 The CMM5 (Cluster Management Module) is the latest generation of solutions for the distribution of TDD Sync signals and “Power-over-Ethernet (PoE)” in the field. The CMM5 is a modular design with individual 4-port power injectors and an optional controller used for remote management. Key features of the CMM5 include:  Support for Gigabit Ethernet (1000BaseT)  Modular and scalable from 4 ports to 32 ports  Direct +/- 48VDC input (optional AC/DC power supplies are available from Cambium Networks)  Uses Cambium Networks UGPS for a synchronization source  Dual resilient power inputs  Rack mountable  Secure remote management when used with the optional CMM5 Controller Module  Support for PMP 450m (cnMedusa™)  Future support for integration into (cnMedusa™) for cloud or NOC-based management It consists of four subsystems, described in the following sections:  CMM5 Controller Module  CMM5 Injector (29 volt and 56 volt versions)  Power supply(s) (240/600 watt)  UGPS Cluster Management: Scenario 1 The following is a CMM5 Cluster Management scenario using four PMP 450i Access Points.

Chapter 2: System hardware GPS synchronization Page 2-51 CMM4 (Rack Mount) The Cluster Management Module (CMM) is the heart of the Cambium system’s synchronization capability, which allows network operators to reuse frequencies and add capacity while ensuring consistency in the quality of service to customers. For operators who prefer indoor CMM mounting, Cambium offers the Rack-Mounted Cluster Management Module 4. The unit is designed to be mounted onto a standard 19-inch telecommunications rack and to allow the Cambium CMM4 to be co-located with other telecommunications equipment. Figure 33 CMM4 (Rack Mount) The CMM4 has two DC power inputs, one 29 V and one 56V. It can be used to power and synchronize both 29 V legacy products such as the PMP 450 Series and 56V products such as the PMP 450i Series simultaneously. If the 29 V legacy products are connected to the CMM4, a 29 V power supply needs to be connected. If the 450i Series is connected to the CMM4, a 56 V power supply needs to be connected. The CMM4 supports having two of the 56 V and two of the 29 V supplies for redundancy. Warning PMP 450i Series requires different wiring between the CMM4 and device. If a PMP450 Series ODU is replaced by a PMP 450i Series and the existing drop cable needs to be re-used, the Ethernet cable adapter for CMM4 - N000045L001A" must be used between the CMM4 and the existing drop cable.

Chapter 2: System hardware GPS synchronization Page 2-54 CMM4 (Cabinet with switch) Designed to deliver consistent and reliable wireless broadband service, the PMP/PTP system gracefully scales to support large deployments. The cluster management module is the heart of the system’s synchronization capability which allows network operators to re-use frequencies and add capacity while ensuring consistency in the quality of service to customers. As a result, subscribers can experience carrier-grade service even at the outer edge of the network. Figure 36 CMM4 (Cabinet with switch) CMM4 (Cabinet without switch) This CMM includes all of the functionality listed above but there is no switch. This provides the network operator the flexibility to use the switch of their choice with the power and synchronization capabilities of the CMM4.

Chapter 2: System hardware GPS synchronization Page 2-55 CMM3/CMMmicro The CMM3 or CMMmicro (Cluster Management Module micro) provides power, GPS timing, and networking connections for an AP cluster. The CMM3 is configurable through a web interface. The CMM3 contains an 8-port managed switch that supports Power over Ethernet (PoE – this is Cambium PoE, not the standard PoE) on each port and connects any combination of APs, BHMs, BHSs, or Ethernet feed. The Cambium fixed wireless broadband IP networks PoE differs from IEEE Standard 803.3af PoE, and the two should not be intermixed. The CMM3 can auto-negotiate speed to match inputs that are either 100Base-TX or 10Base-T, and either full duplex or half duplex, where the connected device is set to auto-negotiate. Alternatively, these parameters are settable. A CMM3 requires only one cable, terminating in an RJ-45 connector, for each connected module to distribute  Ethernet signaling.  power to as many as 8 co-located modules—APs, BHMs, or BHSs. Through a browser interface to the managed switch, ports can be powered or not.  sync to APs and BHMs. The CMM3 receives 1-pulse per second timing information from Global Positioning System (GPS) satellites through an antenna (included) and passes the timing pulse embedded in the 24-V power to the connected modules. GPS status information is available at the CMM3, however  CMM3 provides time and date information to BHMs and APs if both the CMMmicro is operating on CMMmicro Release 2.1 or later and the AP/BHM is operating on System Release 4.2 or later. See Configuring time settings on Page 7-17.  CMM3 does not provide time and date information to BHMs and APs if either the CMM3 is operating on a release earlier than CMMmicro Release 2.1 or the AP/BHM is operating on a release earlier than System Release 4.2. A CMM3/CMMicro is shown in Figure 37 and Figure 38.

Chapter 3: System planning Typical deployment Page 3-2 Typical deployment This section contains diagrams illustrating typical PMP/PTP 450 Platform site deployments. ODU with PoE interface to PSU In the basic configuration, there is only one Ethernet interface, a copper cable for power over Ethernet (POE) from the PSU to the ODU (PSU port), as shown in the following diagrams: mast or tower installation (Figure 40 ), wall installation (Figure 41) and roof installation (Figure 42).

Chapter 3: System planning Site planning Page 3-7 Site planning This section describes factors to be considered when choosing sites for PMP or PTP radios, power supplies, CMM4 (if applicable) and UGPS (if applicable). Site selection for PMP/PTP radios When selecting a site for the ODU, consider the following factors:  Height and location to ensure that people are kept away from the antenna; see Calculated distances and power compliance margins on page 4-24.  Height and location to achieve the best radio path.  Indoor location where the power supply LED indicators will be visible, so the drop cable length will not exceed the maximum recommended length; see Power supply site selection on page 3-8.  Ability to meet the requirements specified in Grounding and lightning protection on page 3-8.  Aesthetics and planning permission issues.  Cable lengths; see Ethernet standards and cable lengths on page 2-33.  The effect of strong winds on the installation; see ODU wind loading on page 3-11.

Chapter 3: System planning Site planning Page 3-8 Power supply site selection When selecting a site for the ODU power supply, consider the following factors:  Indoor location with no possibility of condensation, flooding or high humidity.  Availability of a mains electricity supply.  Located in an environment where it is not likely to exceed its operational temperature rating, allowing for natural convection cooling.  Accessibility for viewing status indicator LED and connecting Ethernet cables.  Cable lengths; see Ethernet standards and cable lengths on page 2-33. Maximum cable lengths When installing PMP/PTP 450i Series ODU, the maximum permitted length of the shielded copper Ethernet interface cable is 330 feet (100m) from AP/BHM/SM/BHS to their associated power supplies or CMM4. When installing PMP 450m Series ODU, the maximum permitted length of the shielded copper Ethernet interface cable is 330 feet ( 100m) from ODU to the network interface equipment. Grounding and lightning protection Warning Electro-magnetic discharge (lightning) damage is not covered under warranty. The recommendations in this guide, when followed correctly, give the user the best protection from the harmful effects of EMD. However 100% protection is neither implied nor possible. Structures, equipment and people must be protected against power surges (typically caused by lightning) by conducting the surge current to ground via a separate preferential solid path. The actual degree of protection required depends on local conditions and applicable local regulations. To adequately protect a PMP/PTP 450 Platform installation, both ground bonding and transient voltage surge suppression are required. Full details of lightning protection methods and requirements can be found in the international standards IEC 61024-1 and IEC 61312-1, the U.S. National Electric Code ANSI/NFPA No. 70-1984 or section 54 of the Canadian Electric Code. Warning International and national standards take precedence over the requirements in this guide.

Chapter 3: System planning Site planning Page 3-9 Lightning protection zones Use the rolling sphere method (Figure 45) to determine where it is safe to mount equipment. An imaginary sphere, typically 50 meters in radius, is rolled over the structure. Where the sphere rests against the ground and a strike termination device (such as a finial or ground bar), all the space under the sphere is considered to be in the zone of protection (Zone B). Similarly, where the sphere rests on two finials, the space under the sphere is considered to be in the zone of protection. Figure 45 Rolling sphere method to determine the lightning protection zones Zone A: In this zone a direct lightning strike is possible. Do not mount equipment in this zone. Zone B: In this zone, direct EMD (lightning) effects are still possible, but mounting in this zone significantly reduces the possibility of a direct strike. Mount equipment in this zone. Warning Never mount equipment in Zone A. Mounting in Zone A may put equipment, structures and life at risk.

Chapter 3: System planning Site planning Page 3-10 Site grounding system Confirm that the site has a correctly installed grounding system on a common ground ring with access points for grounding the 450 Platform Family ODU. If the outdoor equipment is to be installed on the roof of a high building (Figure 42), confirm that the following additional requirements are met:  A grounding conductor is installed around the roof perimeter to form the main roof perimeter lightning protection ring.  Air terminals are installed along the length of the main roof perimeter lightning protection ring, typically every 6.1m (20ft).  The main roof perimeter lightning protection ring contains at least two down conductors connected to the grounding electrode system. The down conductors should be physically separated from one another, as far as practical. ODU and external antenna location Find a location for the ODU (and external antenna for connectorized units) that meets the following requirements:  The equipment is high enough to achieve the best radio path.  People can be kept a safe distance away from the equipment when it is radiating. The safe separation distances are defined in Calculated distances and power compliance margins on page 4-24.  The equipment is lower than the top of the supporting structure (tower, mast or building) or its lightning air terminal.  If the ODU is connectorized, select a mounting position that gives it maximum protection from the elements, but still allows easy access for connecting and weatherproofing the cables. To minimize cable losses, select a position where the antenna cable lengths can be minimized. If diverse or two external antennas are being deployed, it is not necessary to mount the ODU at the midpoint of the antennas. ODU ambient temperature limits Select a location where the ODU can operate within safe ambient temperature limits. The following points need to be considered while selecting a location for the ODU:  The ODU must be mounted in a Restricted Access Location (as defined in EN 60950-1) if the operating ambient temperature may exceed 40°C, including solar radiation.  If the ambient temperature never exceeds 40°C, the temperature of the external metal case parts of the ODU will not exceed the touch temperature limit of 70°C.  If the ambient temperature never exceeds 60°C, the temperature of the external metal case parts of the ODU will not exceed the touch temperature limit of 90°C.

Chapter 3: System planning Site planning Page 3-11 Note A restricted access location is defined (in EN 60950-1) as one where access may only be gained by use of a tool or lock and key, or other means of security, and access is controlled by the authority responsible for the location. Access must only be gained by persons who have been instructed about the reasons for the restrictions applied to the location and about any precautions that must be taken. Examples of permissible restricted access locations are a lockable equipment room or a lockable cabinet. ODU wind loading Ensure that the ODU and the structure on which it is mounted are capable of withstanding the prevalent wind speeds at a proposed 450 Platform site. Wind speed statistics are available from national meteorological offices. The ODU and its mounting bracket are capable of withstanding wind speeds of:  Up to 200 mph (322 kph) for PMP 450m Series – AP 5 GHz  Up to 124 mph (Integrated) for PMP/PTP 450i – all models 3 GHz and 5 GHz  Up to 200 mph (Connectorized) for PMP/PTP 450i – all models 3 GHz and 5 GHz  Up to 200 mph (322 kph) for PMP/PTP 450 – all models  Up to 200 mph (322 kph) for PMP 450 – Ruggedized  Up to 200 mph (322 kph) for PMP 450i – all models 900 MHz  Up to 118 mph (191 kph) for PMP 450b  Up to 90 mph (145 kph) for PMP 450d  Up to 100 mph (161 kph) for 900 MHz antennas Wind blowing on the ODU will subject the mounting structure to significant lateral force. The magnitude of the force depends on both wind strength and surface area of the ODU. Wind loading is estimated using the following formulae:  Force (in kilograms) = 0.1045aV2 where: o “a” is the surface area in square meters, and o “V” is the wind speed in meters per second.  Force (in pounds) = 0.0042Av2 where: o “A” is the surface area in square feet, and o “v” is the wind speed in miles per hour. Applying these formulae to the 450 platform at different wind speeds, the resulting wind loadings are shown in below tables.

Chapter 3: System planning Site planning Page 3-15 Hazardous locations Check that the ODUs will not be exposed to hazardous gases, as defined by HAZLOC (USA) and ATEX (Europe) regulations. If there is a risk of such exposure, then order the PTP/PMP 450i ATEX/Hazloc product variants, as these are intended for operation in locations with gas hazards. The ATEX and HAZLOC standards limit the EIRP as shown in Table 75.

For mast or tower installations (Figure 40), use the following additional criteria:  The drop cable shield must be grounded at the bottom of the tower, near the vertical to horizontal transition point. This ground cable must be bonded to the tower or tower ground bus bar (TGB), if installed.

Chapter 3: System planning Site planning Page 3-16  If the tower is greater than 61 m (200 ft) in height, the drop cable shield must be grounded at the tower midpoint, and at additional points as necessary to reduce the distance between ground cables to 61 m (200 ft) or less.  In high lightning-prone geographical areas, the drop cable shield must be grounded at spacing between 15 to 22 m (50 to 75 ft). This is especially important on towers taller than 45 m (150 ft). For roof installations (Figure 42), use the following additional criteria:  The drop cable shield must be bonded to the building grounding system at its top entry point (usually on the roof).  The drop cable shield must be bonded to the building grounding system at the entry point to the equipment room. Lightning Protection Unit (LPU) location Find a location for the bottom LPU that meets the following requirements:  The bottom LPU can be connected to the drop cable from the ODU.  The bottom LPU is within 600 mm (24 in) of the point at which the drop cable enters the building, enclosure or equipment room within a larger building.  The bottom LPU can be bonded to the grounding system.

Chapter 3: System planning Radio Frequency planning Page 3-17 Radio Frequency planning This section describes how to plan 450 Platform Family links to conform to analysis of spectrum and the regulatory restrictions that apply in the country of operation. Regulatory limits Many countries impose EIRP limits (Allowed EIRP) on products operating in the bands used by the 450 Platform Family. Refer to Equipment Disposal (Chapter 10: Reference information) on page 10-49 to determine what the maximum transmitted power and EIRP for PMP/PTP 450 Plaftrom that can be used in each of countries and frequency band. Caution It is the responsibility of the user to ensure that the PMP/PTP ODU is operated in accordance with local regulatory limits. Note Contact the applicable radio regulator to find out whether or not registration of the PMP/PTP 450 Platform link is required. Conforming to the limits Ensure the link is configured to conform to local regulatory requirements by configuring the PMP 450/450i Series AP or PTP 450/450i Series BHM for the correct country. In the following situations, this does not prevent operation outside the regulations:  When using connectorized ODUs with external antennas, the regulations may require the maximum transmit power to be reduced. Available spectrum The available spectrum for operation depends on the regulatory band. When configured appropriately, the unit will only allow operation on those channels which are permitted by the regulations.

Chapter 3: System planning Radio Frequency planning Page 3-18 Certain regulations have allocated certain channels as unavailable for use:  FCC has allocated part of the 5.1 & 5.2 GHz  ETSI has allocated part of the 5.4 GHz band to weather radar.  UK and some other European countries have allocated part of the 5.8 GHz band to Road Transport and Traffic Telematics (RTTT) systems. The number and identity of channels barred in a given regulatory band is dependent on the channel bandwidth and channel raster selected. Analyzing the RF Environment An essential element in RF network planning is the analysis of spectrum usage and the strength of the signals that occupy the spectrum. Regardless of how these parameters are measured and log or chart the results (through the Spectrum Analyzer feature or by using a spectrum analyzer), ensure measurements are performed:  At various times of day.  On various days of the week.  Periodically into the future. As new RF neighbors move in or consumer devices proliferate in currently used spectrum, this keeps the user aware of the dynamic possibilities for interference within the network. Channel bandwidth Select the required channel bandwidth for the link. The selection depends upon the regulatory band selected. The wider the channel bandwidth, the greater the capacity. As narrower channel bandwidths take up less spectrum, selecting a narrow channel bandwidth may be a better choice when operating in locations where the spectrum is very busy. Both ends of the link must be configured to operate on the same channel bandwidth. Anticipating Reflection of Radio Waves In the signal path, any object that is larger than the wavelength of the signal can reflect the signal. Such an object can even be the surface of the earth or of a river, bay or lake. The wavelength of the signal is approximately  2 inches (or 5 cm) for 5.4 GHz and 5.8 GHz signals.  12 inches for 900 MHz signals A reflected signal can arrive at the antenna of the receiver later than the non-reflected signal arrives. These two or more signals cause the condition known as multipath. Multipath may increase or decrease the signal level, resulting in overall attenuation that may be higher or lower than that caused by the link distance. This is problematic at the margin of the link budget, where the standard operating margin (fade margin) may be compromised.

Chapter 3: System planning Radio Frequency planning Page 3-19 Obstructions in the Fresnel Zone The Fresnel (pronounced fre∙NEL) Zone is a three-dimensional volume around the line of sight of an antenna transmission. Objects that penetrate this area can cause the received strength of the transmitted signal to fade. Out-of-phase reflections and absorption of the signal result in signal cancellation. The foliage of trees and plants in the Fresnel Zone can cause signal loss. Seasonal density, moisture content of the foliage, and other factors such as wind may change the amount of loss. Plan to perform frequent and regular link tests if you must transmit through foliage. Planning for co-location The first step to avoid interference in wireless systems is to set all AP/BHMs to receive timing from a synchronization source (Cluster Management Module, or Universal Global Positioning System). This ensures that the modules are in sync and start transmitting at the same time each frame. The second step to avoid interference is to configure parameters on all AP/BHMs of the same frequency band in proximity such that they have compatible transmit/receive ratios (all stop transmitting each frame before any start receiving). This avoids the problem of one AP/BHM attempting to receive the signal from a distant SM/BHS while a nearby AP/BHM transmits, which could overpower that signal. Note Refer to Frame Alignment Legacy Mode parameter of Configuration > Radio > Adavance tab for legacy product settings (See Table 142 PMP 450i AP Radio attributes - 5 GHz on page 7-132). The following parameters on the AP/BHM determine the transmit/receive ratio:  Downlink Data percentage  Frame Period  Max Range  (reserved) Contention slots If OFDM (450 Platform Family, PMP/PTP 230) and FSK (PMP/PTP 1x0) APs/BHMs of the same frequency band and channel bandwidth are in proximity, or if you want BHMs set to different parameters then you must use the Frame Calculator to identify compatible settings for APs/BHMs. The co-location is also supported for 900 MHz PMP 450i Series APs (OFDM) and PMP 100 Series APs (FSK). The Frame Calculator is available on the web management interface Tools > Frame Calculator. To use the Frame Calculator, type into the calculator various configurable parameter values for each proximal AP/BHM and then record the resulting AP/BHM Receive Start value. Next vary the Downlink Data percentage in each calculation and iterate until a calculated AP/BHM Receive Start for all co-located AP/BHMs where the transmit end does not come before the receive start. Cambium also provides co-location tool which helps in co-location planning:  https://support.cambiumnetworks.com/files/colocationtool

Chapter 3: System planning Radio Frequency planning Page 3-20 For more information on 450 Platform Family co-location, see http://www.cambiumnetworks.com/solution-papers Multiple OFDM Access Point Clusters When deploying multiple AP clusters in a dense area, consider aligning the clusters as shown below. However, this is only a recommendation. An installation may dictate a different pattern of channel assignments.

Chapter 3: System planning Radio Frequency planning Page 3-22 Considerations on back-to-back frequency reuse Cambium Networks recommends to use back-to-back (ABAB) frequency reuse, as shown in Figure 46. This means that a base site of four sectors can be created using two frequencies, which works very well and helps define networks in situations where high capacity is required in a limited amount of spectrum. The conditions necessary to implement this plan are:  GPS synchronization: all the access points transmit at the same time  Uplink and Downlink timings across APs do not overlap: they can be adjusted using the frame calculators and co-location tools provided by Cambium  Uplink power control to ensure that all signals are received on the uplink at the same level: this is automatically enabled on all sectors  There are no reflecting objects which are too large in the exclusion zones defined in this section.  The SMs do not normally have line-of-sight (LoS) to an interfering base station. The worst case range ratio in Figure 46 is 5:1 which in LoS only gives 14 dB protection. Greater than 30 dB is required for 256QAM capability. Down tilt can be used to advantage when the elevation beamwidth is low. Also the range ratio applies to the longest distance SM, shorter distance SMs have a better range ratio. This frequency reuse plan may not always give 256QAM for the longest distance SMs. It is usually a good compromise between using more spectrum and guaranteed modulation rate. Reflecting objects Figure 48 shows two diagrams of the same reflecting object. Uplink interference demonstrates the situation when the two SMs are transmitting at the same time. SM2 should be received cleanly by the AP for Sector 3. At the same time interference can arise from SM1 via the reflecting object and cause a lower Signal-to-Interference ratio than required at AP3. This may either cause transmission errors which are corrected by ARQ or cause the selected modulation rate to be lowered. Either may cause a lower throughput from SM2 and therefore sector 3. Downlink interference shows the situation when AP3 interferes with SM1. Again the transmission may be reduced by errors or a reduction in modulation rate.

Chapter 3: System planning Radio Frequency planning Page 3-23 Figure 48 Reflection Reflection likelihood guidance As shown in the previous section, reflection can cause a decrease in throughput in an ABAB base site. This section provides guidance on whether a reflection is likely to cause interference. The first condition for whether a reflection can cause the data rate to reduce is that the reflecting object must be in view of the AP and the SM in order to re-transmit the signal. If this is not the case, then the object cannot cause interference. Given that the potential reflecting object is seen by the AP and the SM, there are a range of object sizes and a range of zones where we can predict that interference will occur which may reduce the throughput when both sector 1 and sector 3 are carrying traffic. Figure 49 and Figure 50 show regions enumerated A, B, C, and D. We also need to consider objects of size 1, 2, 3 and 4 and define the areas where the objects may interfere.  object size 1: a flat building face with a clear reflecting property from sector to AP  object size 2: random metalwork such as a wireless tower  object size 3: a 0.5 X 0.5m flat metallic face or tree  object size 4: a 0.2 X 0.2m random metal structure or 0.5 X 0.5m foliage. The conditions for no interference are:  size 2 outside zone B  size 3 outside zone C  size 4 outside zone D The size 1 object can interfere at large distances. It is necessary to look at the geometry by which reflection could occur and cause interference. Typically, this will occur at a restricted range of azimuths and ranges.

In each figure the distances and heights assume a typical down tilt of 4°. In each figure the top diagram represents the clearances required at zero azimuth. The middle diagram represents the scaling required to the top diagram to allow for differences in azimuth of the considered reflecting object. The bottom diagram is the scaled version of the top diagram allowing for the dotted azimuth line in the middle diagram.PMP 450m Series planning PMP 450m Series AP is based on Massive MU-MIMO technology. It is a 14x14 MIMO system which allows simultaneous communication to up to seven SMs. Figure 51 PMP 450m Series AP antenna beam PMP 450m installation recommendations.

Chapter 3: System planning Radio Frequency planning Page 3-27  For best performance it is recommended to have a clearance zone around the mast. The clearance zone depends on the surrounding environment and the antenna’s down tilt. If the mast is surrounded by metal then larger clearance is required compared to an environment where the antenna is surrounded by foliage  SMs should be spread in azimuth of AP antenna  450m is susceptible to movement, for best MU-MIMO performance it is recommended that the 450m AP is mounted/installed on a mast that is extremely rigid (no movement and is 100% vertical).  LINKPlanner can be used to plan SMs across the AP antenna azimuth

Chapter 3: System planning Link planning Page 3-28 Link planning This section describes factors to be taken into account when planning links, such as range, obstacles path loss and throughput. LINKPlanner is recommended. Range and obstacles Calculate the range of the link and identify any obstacles that may affect radio performance. Perform a survey to identify all the obstructions (such as trees or buildings) in the path and to assess the risk of interference. This information is necessary in order to achieve an accurate link feasibility assessment. The 450 Platform Family is designed to operate in Non-Line-of-Sight (NLoS) and Line-of-Sight (LoS) environments. An NLOS environment is one in which there is no optical line-of-sight, that is, there are obstructions between the antennas. OFDM technology can often use multi-pathing to an advantage to overcome nLOS, especially in cases where the Fresnel zone is only partially blocked by buildings, “urban canyons”, or foliage. OFDM tends to help especially when obstacles are near the middle of the link, and less so when the obstacles are very near the ODU. However, attenuation through walls and trees is substantial for any use of the 5.4 GHz and 5.8 GHz frequency bands. The lower frequency radio waves of 900 MHz radios provide greater penetration through walls, trees and other obstacles, making it optimal for most non-line-of-sight applications. Even with OFDM, these products are not expected to penetrate walls or extensive trees and foliage. Path loss Path loss is the amount of attenuation the radio signal undergoes between the two ends of the link. The path loss is the sum of the attenuation of the path if there were no obstacles in the way (Free Space Path Loss), the attenuation caused by obstacles (Excess Path Loss) and a margin to allow for possible fading of the radio signal (Fade Margin). The following calculation needs to be performed to judge whether a particular link can be installed: capabilityseasonalfadeexcessspacefree LLLLL _ Where: Is: spacefreeL_ Free Space Path Loss (dB) excessL Excess Path Loss (dB) fadeL Fade Margin Required (dB) seasonaL Seasonal Fading (dB)

Chapter 3: System planning Link planning Page 3-29 capabilityL Equipment Capability (dB) Calculating Link Loss The link loss is the total attenuation of the wireless signal between two point-to-multipoint units. The link loss calculation is presented below: Link Loss (dB) = Transmit power of the remote wireless unit (dBm) − Tx Cable loss (dB) − Received power at the local unit (dBm) – Rx cable loss (dB) + Antenna gain at the remote unit (dBi) + Antenna gain at the local unit (dBi) Calculating Rx Signal Level The determinants in Rx signal level are illustrated in Figure 52. Figure 52 Determinants in Rx signal level Rx signal level is calculated as follows: Rx signal level dB = Tx power − Tx cable loss + Tx antenna gain − free space path loss + Rx antenna gain − Rx cable loss Note This Rx signal level calculation presumes that a clear line of sight is established between the transmitter and receiver and that no objects encroach in the Fresnel zone.

Chapter 3: System planning Link planning Page 3-30 Calculating Fade Margin Free space path loss is a major determinant in Rx (received) signal level. Rx signal level, in turn, is a major factor in the system operating margin (fade margin), which is calculated as follows: System operating margin (fade margin) dB = Rx signal level dB − Rx sensitivity dB Thus, fade margin is the difference between strength of the received signal and the strength that the receiver requires for maintaining a reliable link. A higher fade margin is characteristic of a more reliable link. Adaptive modulation Adaptive modulation ensures that the highest throughput that can be achieved instantaneously will be obtained, taking account of propagation and interference. When the link has been installed, web pages provide information about the link loss currently measured by the equipment, both instantaneously and averaged. The averaged value will require maximum seasonal fading to be added, and then the radio reliability of the link can be computed. For details of the system throughput, link loss and maximum distance for each frequency band in all modulation modes, see Link on page 10-45.

Chapter 3: System planning Planning for connectorized units Page 3-31 Planning for connectorized units This section describes factors to be taken into account when planning to use connectorized ODUs with external antennas in 450 Platform Family links. When to install connectorized units The majority of radio links can be successfully deployed with the integrated ODU. However the integrated units may not be sufficient in some areas, for example:  Where the path is heavily obscured by dense woodland on an NLOS link.  Where long LOS links are required.  Where there are known to be high levels of interference. In these areas, connectorized ODUs and external antennas should be used. Choosing external antennas When selecting external antennas, consider the following factors:  The required antenna gain.  Ease of mounting and alignment.  Use dual-polarization antenna (as the integrated antenna). Note Enter the antenna gain and cable loss into the Installation Wizard, if the country selected has an EIRP limit, the corresponding maximum transmit power will be calculated automatically by the unit. Calculating RF cable length (5.8 GHz FCC only) The 5.8 GHz band FCC approval for the product is based on tests with a cable loss between the ODU and antenna of not less than 1.2 dB. If cable loss is below 1.2 dB with a 1.3 m (4 ft) diameter external antenna, the connectorized 450 Platform Family may exceed the maximum radiated spurious emissions allowed under FCC 5.8 GHz rules. Cable loss depends mainly upon cable type and length. To meet or exceed the minimum loss of 1.2 dB, use cables of the type and length specified in Table 78 (source: Times Microwave). This data excludes connector losses. Table 78 RF cable lengths required to achieve 1.2 dB loss at 5.8 GHz RF cable type Minimum cable length

Chapter 3: System planning Data network planning Page 3-33 Data network planning This section describes factors to be considered when planning 450 Platform Family data networks. Understanding addresses A basic understanding of Internet Protocol (IP) address and subnet mask concepts is required for engineering your IP network. IP address The IP address is a 32-bit binary number that has four parts (octets). This set of four octets has two segments, depending on the class of IP address. The first segment identifies the network. The second identifies the hosts or devices on the network. The subnet mask marks a boundary between these two sub-addresses. Dynamic or static addressing For any computer to communicate with a module, the computer must be configured to either  use DHCP (Dynamic Host Configuration Protocol). In this case, when not connected to the network, the computer derives an IP address on the 169.254 network within two minutes.  have an assigned static IP address (for example, 169.254.1.5) on the 169.254 network. Note If an IP address that is set in the module is not the 169.254.x.x network address, then the network operator must assign the computer a static IP address in the same subnet. When a DHCP server is not found To operate on a network, a computer requires an IP address, a subnet mask, and possibly a gateway address. Either a DHCP server automatically assigns this configuration information to a computer on a network or an operator must input these items. When a computer is brought on line and a DHCP server is not accessible (such as when the server is down or the computer is not plugged into the network), Microsoft and Apple operating systems default to an IP address of 169.254.x.x and a subnet mask of 255.255.0.0 (169.254/16, where /16 indicates that the first 16 bits of the address range are identical among all members of the subnet).

Chapter 3: System planning Data network planning Page 3-34 DNS Client The DNS Client is used to resolve names of management servers within the operator’s management domain (see Figure 53). This feature allows hostname configuration for NTP servers, Authorization Servers, DHCP relay servers, and SNMP trap servers. Operators may choose to either enter in the FQDN (Fully Qualified Domain Name) for the host name or to manually enter the IP addresses of the servers. Figure 53 Cambium networks management domain Network Address Translation (NAT) NAT, DHCP Server, DHCP Client and DMZ in SM The system provides NAT (network address translation) for SMs in the following combinations of NAT and DHCP (Dynamic Host Configuration Protocol):  NAT Disabled  NAT with DHCP Client (DHCP selected as the Connection Type of the WAN interface) and DHCP Server  NAT with DHCP Client(DHCP selected as the Connection Type of the WAN interface)  NAT with DHCP Server  NAT without DHCP NAT NAT isolates devices connected to the Ethernet/wired side of a SM from being seen directly from the wireless side of the SM. With NAT enabled, the SM has an IP address for transport traffic (separate from its address for management), terminates transport traffic, and allows you to assign a range of IP addresses to devices that are connected to the Ethernet/wired side of the SM.

Chapter 3: System planning Data network planning Page 3-35 In the Cambium system, NAT supports many protocols, including HTTP, ICMP (Internet Control Message Protocols), and FTP (File Transfer Protocol). For virtual private network (VPN) implementation, L2TP over IPSec (Level 2 Tunneling Protocol over IP Security) and PPTP (Point to Point Tunneling Protocol) are supported. DHCP DHCP enables a device to be assigned a new IP address and TCP/IP parameters, including a default gateway, whenever the device reboots. Thus DHCP reduces configuration time, conserves IP addresses, and allows modules to be moved to a different network within the Cambium system. In conjunction with the NAT features, each SM provides:  A DHCP server that assigns IP addresses to computers connected to the SM by Ethernet protocol.  A DHCP client that receives an IP address for the SM from a network DHCP server. DMZ In conjunction with the NAT features, a DMZ (demilitarized zone) allows the assignment of one IP address behind the SM for a device to logically exist outside the firewall and receive network traffic. The first three octets of this IP address must be identical to the first three octets of the NAT private IP address. Developing an IP addressing scheme Network elements are accessed through IP Version 4 (IPv4) addressing. A proper IP addressing method is critical to the operation and security of a network. Each module requires an IP address on the network. This IP address is for only management purposes. For security, you must either:  Assign a non-routable IP address.  Assign a routable IP address only if a firewall is present to protect the module. You assign an IP addresses to computers and network components by either static or dynamic IP addressing. You will also assign the appropriate subnet mask and network gateway to each module. Address Resolution Protocol As previously stated, the MAC address identifies a module in:  Communications between modules.  The data that modules store about each other. The IP address is essential for data delivery through a router interface. Address Resolution Protocol (ARP) correlates MAC addresses to IP addresses.

Chapter 3: System planning Data network planning Page 3-36 For communications to outside the network segment, ARP reads the network gateway address of the router and translates it into the MAC address of the router. Then the communication is sent to MAC address (physical network interface card) of the router. For each router between the sending module and the destination, this sequence applies. The ARP correlation is stored until the ARP cache times out. Allocating subnets The subnet mask is a 32-bit binary number that filters the IP address. Where a subnet mask contains a bit set to 1, the corresponding bit in the IP address is part of the network address. Example IP address and subnet mask In Figure 54, the first 16 bits of the 32-bit IP address identify the network: Figure 54 Example of IP address in Class B subnet Octet 1 Octet 2 Octet 3 Octet 4 IP address 169.254.1.1 10101001 11111110 00000001 00000001 Subnet mask 255.255.0.0 11111111 11111111 00000000 00000000 In this example, the network address is 169.254 and 216 (65,536) hosts are addressable. Selecting non-routable IP addresses The factory default assignments for network elements are:  Unique MAC address  IP address of 169.254.1.1  Subnet mask of 255.255.0.0  Network gateway address of 169.254.0.0 For each radio and CMM4, assign an IP address that is both consistent with the IP addressing plan for your network and cannot be accessed from the Internet. IP addresses within the following ranges are not routable from the Internet, regardless of whether a firewall is configured:  10.0.0.0 – 10.255.255.255  172.16.0.0 – 172.31.255.255  192.168.0.0 – 192.168.255.255 Also, the subnet mask and network gateway for each CMM4 can be assigned. Translation bridging Optionally, the AP can be configured to change the source MAC address in every packet it receives from its SMs to the MAC address of the SM/BHS that bridged the packet, before forwarding the packet toward the public network. In this case:

Chapter 3: System planning Data network planning Page 3-37  Not more than 128 IP devices at any time are valid to send data to the AP from behind the SM.  SM populates the Translation Table tab of its Statistics web page, displaying the MAC address and IP address of all the valid connected devices.  Each entry in the Translation Table is associated with the number of minutes that have elapsed since the last packet transfer between the connected device and the SM.  If 128 are connected, and another attempts to connect: o If no Translation Table entry is older than 255 minutes, the attempt is ignored. o If an entry is older than 255 minutes, the oldest entry is removed and the attempt is successful.  The Send Untranslated ARP parameter in the General tab of the Configuration page can be: o Disabled, so that the AP overwrites the MAC address in ARP packets before forwarding them. o Enabled, so that the AP forwards ARP packets regardless of whether it has overwritten the MAC address. This is the Translation Bridging feature, which you can enable in the General page of the Configuration web page in the AP. When this feature is disabled, the setting of the Send Untranslated ARP parameter has no effect, because all packets are forwarded untranslated (with the source MAC address intact). See Address Resolution Protocol on Page 3-35. Engineering VLANs The radios support VLAN functionality as defined in the 802.1Q (Virtual LANs) specification, except for the following aspects of that specification:  Protocols: o Generic Attribute Registration Protocol (GARP) GARV o Spanning Tree Protocol (STP) o Multiple Spanning Tree Protocol (MSTP) o GARP Multicast Registration Protocol (GMRP)  Embedded source routing (ERIF) in the 802.1Q header  Multicast pruning  Flooding unknown unicast frames in the downlink As an additional exception, the AP/BHM does not flood downward the unknown unicast frames to the SM/BHS. A VLAN configuration in Layer 2 establishes a logical group within the network. Each computer in the VLAN, regardless of initial or eventual physical location, has access to the same data. For the network operator, this provides flexibility in network segmentation, simpler management, and enhanced security.

Chapter 3: System planning Data network planning Page 3-38 Special case VLAN numbers This system handles special case VLAN numbers according to IEEE specifications: Table 79 Special case VLAN IDs VLAN Number Purpose Usage Constraint 0 These packets have 802.1p priority, but are otherwise handled as untagged. Must not be used as a management VLAN. 1 Although not noted as special case by IEEE specifications, these packets identify traffic that was untagged upon ingress into the SM and must remain untagged upon egress. This policy is hard-coded in the AP. Must not be used for system VLAN traffic. 4095 This VLAN is reserved for internal use. Must not be used at all. SM membership in VLANs With the supported VLAN functionality, the radios determine bridge forwarding on the basis of not only the destination MAC address, but also the VLAN ID of the destination. This provides flexibility in how SMs are used:  Each SM can be a member in its own VLAN.  Each SM can be in its own broadcast domain, such that only the radios that are members of the VLAN can see broadcast and multicast traffic to and from the SM.  The network operator can define a work group of SMs, regardless of the AP(s) to which they register.

Chapter 3: System planning Data network planning Page 3-39 PMP 450 Platform Family modules provide the VLAN frame filters that are described in Table 80. Table 80 VLAN filters in point-to-multipoint modules Where VLAN is active, if this parameter value is selected … then a frame is discarded if… because of this VLAN filter in the software: entering the bridge/ NAT switch through… Ethernet… TCP/IP… any combination of VLAN parameter settings with a VID not in the membership table Ingress any combination of VLAN parameter settings with a VID not in the membership table Local Ingress Allow Frame Types: Tagged Frames Only with no 802.1Q tag Only Tagged Allow Frame Types: Untagged Frames Only with an 802.1Q tag, regardless of VID Only Untagged Local SM Management: Disable in the SM, or All Local SM Management: Disable in the AP with an 802.1Q tag and a VID in the membership table Local SM Management leaving the bridge/ NAT switch through… Ethernet… TCP/IP… any combination of VLAN parameter settings with a VID not in the membership table Egress any combination of VLAN parameter settings with a VID not in the membership table Local Egress Priority on VLANs (802.1p) The radios can prioritize traffic based on the eight priorities described in the IEEE 802.1p specification. When the high-priority channel is enabled on a SM, regardless of whether VLAN is enabled on the AP for the sector, packets received with a priority of 4 through 7 in the 802.1p field are forwarded onto the high-priority channel. Operators may configure priority precedence as 802.1p Then Diffserv (Default) or Diffserv Then 802.1p. Since these priority precedence configurations are independent between the AP and SM, this setting must be configured on both the AP and SM to ensure that the precedence is adhered to by both sides of the link.

Chapter 3: System planning Data network planning Page 3-40 VLAN settings can also cause the module to convert received non-VLAN packets into VLAN packets. In this case, the 802.1p priority in packets leaving the module is set to the priority established by the DiffServ configuration. If VLAN is enabled, immediately monitor traffic to ensure that the results are as desired. For example, high-priority traffic may block low-priority. Q-in-Q DVLAN (Double-VLAN) Tagging (802.1ad) PMP and PTP modules can be configured with 802.1ad Q-in-Q DVLAN (Double-VLAN) tagging which is a way for an operator to put an 802.1Q VLAN inside of an 802.1ad VLAN. A nested VLAN, which is the original 802.1Q tag and a new second 802.1ad tag, allows for bridging of VLAN traffic across a network and segregates the broadcast domains of 802.1Q VLANs. Q-in-Q can be used with PPPoE and/or NAT. The 802.1ad standard defines the S-VLAN as the Service Provider VLAN and the C-VLAN as the customer VLAN. The radio software does 2 layer Q-in-Q whereby the C-VLAN is the 802.1Q tag and the S-VLAN is the second layer Q tag as shown in Table 81. Table 81 Q-in-Q Ethernet frame Ethernet Header S-VLAN EthType 0x88a8 C-VLAN EthType 0x8100 IP Data EthType 0x0800 The 802.1ad S-VLAN is the outer VLAN that is configurable on the Configuration > VLAN web page of the AP/BHM. The Q-in-Q EtherType parameter is configured with a default EtherType of 0x88a8 in addition to four alternate EtherTypes that can be configured to aid in interoperability with existing networks that use a different EtherType than the default. The C-VLAN is the inner VLAN tag, which is the same as 802.1Q. As a top level concept, this operates on the outermost tag at any given time, either “pushing” a tag on or “popping” a tag off. This means packets will at most transition from an 802.1Q frame to an 801.ad frame (with a tag “pushed” on) or an untagged 802.1 frame (with the tag “popped” off. Similarly, for an 802.1ad frame, this can only transition from an 802.1ad frame to an 802.1Q frame (with the tag “popped” off) since the radio software only supports 2 levels of tags.

Chapter 3: System planning Network management planning Page 3-41 Network management planning This section describes how to plan for 450 Platform Family links to be managed remotely using SNMP. Planning for SNMP operation Cambium modules provide the following SNMP traps for automatic notifications to the NMS:  coldStart, which signals that the SNMPv2c element is reinitializing itself and that its configuration may have been altered.  warmStart, which signals that the SNMPv2c element is reinitializing such that its configuration is unaltered.  authenticationFailure, which signals that the SNMPv2c element has received a protocol message that is not properly authenticated (contingent on the snmpEnableAuthenTraps object setting).  linkDown, as defined in RFC 1573  linkUp, as defined in RFC 1573  egpNeighborLoss, as defined in RFC 1213  whispGPSInSync, which signals a transition from not synchronized to synchronized.  whispGPSOutSync, which signals a transition from synchronized to not synchronized.  whispRegComplete, which signals registration completed.  whispRegLost, which signals registration lost.  whispRadarDetected, which signals that the one-minute scan has been completed, radar has been detected and the radio will shut down.  whispRadarEnd, which signals that the one-minute scan has been completed, radar has not been detected and the radio will resume normal operation. Note The proprietary MIBs are provided in the 450 Platform Family software download files in the support website (see Contacting Cambium Networks on page 1). Enabling SNMP Enable the SNMP interface for use by configuring the following attributes in the SNMP Configuration page:  SNMP State (default disabled)  SNMP Version (default SNMPv2c)  SNMP Port Number (default 161)

Chapter 3: System planning Security planning Page 3-42 Security planning This section describes how to plan for 450 Platform Family links to operate in secure mode.  Managing module access by passwords  Filtering protocols and ports  Port Configuration Isolating AP/BHM from the Internet Ensure that the IP addresses of the AP/BHM in the network:  are not routable over the Internet.  do not share the subnet of the IP address of your user. RFC 1918, Address Allocation for Private Subnets, reserves for private IP networks three blocks of IP addresses that are not routable over the Internet:  /8 subnets have one reserved network, 10.0.0.0 to 10.255.255.255.  /16 subnets have 16 reserved networks, 172.16.0.0 to 172.31.255.255.  /24 subnets have 256 reserved networks, 192.168.0.0 to 192.168.255.255. Encrypting radio transmissions Cambium fixed wireless broadband IP systems employ the following form of encryption for security of the wireless link:  DES (Data Encryption Standard): An over-the-air link encryption option that uses secret 56-bit keys and 8 parity bits. DES performs a series of bit permutations, substitutions, and recombination operations on blocks of data. DES encryption does not affect the performance or throughput of the system.  AES (Advanced Encryption Standard): An over-the-air link encryption option that uses the Rijndael algorithm and 128-bit keys to establish a higher level of security than DES. AES products are certified as compliant with the Federal Information Processing Standards (FIPS 197) in the U.S.A. The default encryption setting for 450 Platform Family ODU is "None".

Chapter 3: System planning Security planning Page 3-43 Planning for HTTPS operation Before starting to configure HTTPS operation, ensure that the cryptographic material listed in Table 82 is available. Table 82 HTTPS security material Item Description Quantity required User Defined Security Banner The banner provides warnings and notices to be read by the user before logging in to the ODU. Use text that is appropriate to the network security policy. Normally one per link. This depends upon network policy. Port numbers for HTTP, HTTPS and Telnet Port numbers allocated by the network. As allocated by network. Planning for SNMPv3 operation SNMP security mode Decide how SNMPv3 security will be configured. MIB-based security management uses standard SNMPv3 MIBs to configure the user-based security model and the view-based access control model. This approach provides considerable flexibility, allowing a network operator to tailor views and security levels appropriate for different types of user. MIB-based security management may allow a network operator to take advantage of built-in security management capabilities of existing network managers. Web-based security management allows an operator to configure users, security levels, privacy and authentication protocols, and passphrases using the 450 Platform Family web-based management interface. The capabilities supported are somewhat less flexible than those supported using the MIB-based security management, but will be sufficient in many applications. Selection of web-based management for SNMPv3 security disables the MIB-based security management. 450 Platform Family does not support concurrent use of MIB-based and web-based management of SNMPv3 security. Web-based management of SNMPv3 security Initial configuration of SNMPv3 security is available only to HTTP or HTTPS user accounts with security role of Security Officer. Identify the format used for SNMP Engine ID. The following formats are available:  MAC address (default)  5 and 32 hex characters (the hex character input is driven by RFC 3411 recommendations on the Engine ID) Identify the user names and security roles of initial SNMPv3 users. Two security roles are available:

Chapter 3: System planning Security planning Page 3-44  Read Only  System Administrator Identify the security level for each of the security roles. Three security levels are available: (a) No authentication, no privacy (b) Authentication, no privacy (c) Authentication, privacy If authentication is required, identify the protocol. The authentication protocol available is MD5. If privacy will be used, identify the protocol. The privacy protocol available is cbc-des. Managing module access by passwords From the factory, each module has a preconfigured administrator-level account in the name root, which initially requires no associated password. When you upgrade a module:  An account is created in the name admin.  Both admin and root inherit the password that was previously used to access the module, if: o Full Access password, if one was set. o Display-Only Access password, if one was set and no Full Access password was set. Caution If you use Wireless Manager, do not delete the root account from any module. If you use a NMS that communicates with modules through SNMP, do not delete the root account from any module unless you first can confirm that the NMS does not rely on the root account for access to the modules. Each module supports four or fewer user accounts, regardless of account levels. The available levels are  ADMINISTRATOR, who has full read and write permissions. This is the level of the root and admin users, as well as any other administrator accounts that one of them creates.  INSTALLER, who has permissions identical to those of ADMINISTRATOR except that the installer cannot add or delete users or change the password of any other user.  TECHNICIAN, who has permissions to modify basic radio parameters and view informational web pages.  GUEST, who has no write permissions and only a limited view of General Status tab.  Admin, Installer and Tech accounts can be configured as READ-ONLY. This will allow the account to only see the items. The ability to view information of General Status tab can be controlled by the "Site Information Viewable to Guest Users" under the SNMP tab. From the factory default state, configure passwords for both the root and admin account at the ADMINISTRATOR permission level, using the Account > Change Users Password page. (If configure only one of these, then the other will still require no password for access into it and thus remain a security risk.) If you are intent on configuring only one of them, delete the admin account. The root account is the only account that CNUT uses to update the module.

Chapter 3: System planning Security planning Page 3-45 After a password has been set for any ADMINISTRATOR-level account, initial access to the module GUI opens the view of GUEST level. Planning for RADIUS operation Configure RADIUS where remote authentication is required for users of the web-based interface. Remote authentication has the following advantages:  Control of passwords can be centralized.  Management of user accounts can be more sophisticated. For example; users can be prompted by a network manager to change passwords at regular intervals. As another example, passwords can be checked for inclusion of dictionary words and phrases.  Passwords can be updated without reconfiguring multiple network elements.  User accounts can be disabled without reconfiguring multiple network elements. Remote authentication has one significant disadvantage in a wireless link product such as 450 Platform Family. If the wireless link is down, a unit on the remote side of the broken link may be prevented from contacting a RADIUS Server, with the result that users are unable to access the web-based interface. One useful strategy would be to combine RADIUS authentication for normal operation with a single locally-authenticated user account for emergency use. PMP 450 Platform Family SM provides a choice of the following authentication methods:  Phase 1: o EAP-MSCHAPv2 o EAP-TTLS o EAP PEAP  Phase 2: o PAP o CHAP o MSCHAPv2 Ensure that the authentication method selected in 450 Platform Family is supported by the RADIUS server. Filtering protocols and ports Configure filters for specified protocols and ports from leaving the AP/BHM and SM/BHS and entering the network. This protects the network from both intended and inadvertent packet loading or probing by network users. By keeping the specified protocols or ports off the network, this feature also provides a level of protection to users from each other. Protocol and port filtering is set per AP/SM/BH. Except for filtering of SNMP ports, filtering occurs as packets leave the AP/SM/BH. For example, if SM is configured to filter SNMP, then SNMP packets are blocked from entering the SM and, thereby, from interacting with the SNMP portion of the protocol stack on the SM.

Chapter 3: System planning Security planning Page 3-46 Port Filtering with NAT Enabled Where NAT is enabled on the SM/BHS, the filtering can be enabled for only the user-defined ports. The following are examples for situations where the configure port can be filtered where NAT is enabled:  To block a subscriber from using FTP, you can filter Ports 20 and 21 (the FTP ports) for both the TCP and UDP protocols.  To block a subscriber from access to SNMP, you can filter Ports 161 and 162 (the SNMP ports) for both the TCP and UDP protocols. Note In only the SNMP case, filtering occurs before the packet interacts with the protocol stack. Protocol and Port Filtering with NAT Disabled Where NAT is disabled on the SM/BHS, the filtering can be enabled for both protocols and the three user-defined ports. Using the check boxes on the interface, it can be either:  Allow all protocols except those that user wish to block.  Block all protocols except those that user wish to allow. Allow or block any of the following protocols:  PPPoE (Point to Point Protocol over Ethernet)  Any or all of the following IPv4 (Internet Protocol version 4) protocols:  Any or all of the following IPv4 (Internet Protocol version 4) protocols: o SMB (Network Neighborhood) o SNMP o Bootp Client o Bootp Server o Up to 3 user-defined ports o All other IPv4 traffic (see Figure 29)  Any or all of the following IPv6 (Internet Protocol version 6) protocols: o SMB (Network Neighborhood) o SNMP o Bootp Client o Bootp Server o Up to 3 user-defined ports o All other IPv6 traffic (see Figure 29)  Filter Direction – Upstream and Downstream  ARP (Address Resolution Protocol)

Chapter 3: System planning Security planning Page 3-47 Figure 55 Categorical protocol filtering The following are example situations in which the protocol filtering is configured where NAT is disabled:  If a subscriber is blocked from only PPPoE and SNMP, then the subscriber retains access to all other protocols and all ports.  If PPPoE, IPv4, and Uplink Broadcast are blocked, and also check the All others selection, then only Address Resolution Protocol is not filtered. The ports filtered as a result of protocol selections in the Protocol Filtering tab of the SM/BHS are listed in Table 83.

Chapter 3: System planning Security planning Page 3-48 Table 83 Ports filtered per protocol selections Port Configuration 450 Platform Family supports access to various communication protocols and only the ports required for these protocols are available for access by external entities. Operators may change the port numbers for these protocols via the radio GUI or SNMP.

Chapter 3: System planning Security planning Page 3-49 Encrypting downlink broadcasts An AP can be enabled to encrypt downlink broadcast packets such as the following:  ARP  NetBIOS  broadcast packets containing video data on UDP. The encryption used is DES for a DES-configured module and AES for an AES-configured module. Before the Encrypt Downlink Broadcast feature is enabled on the AP, air link security must be enabled on the AP. Isolating SMs in PMP In an AP, SMs in the sector can be prevented from directly communicating with each other. In CMM4, the connected APs can be prevented from directly communicating with each other, which prevents SMs that are in different sectors of a cluster from communicating with each other. In the AP, the SM Isolation parameter is available in the General tab of the Configuration web page. Configure the SM Isolation feature by any of the following selections from drop-down menu:  Disable SM Isolation (the default selection). This allows full communication between SMs.  Enable Option 1 - Block SM destined packets from being forwarded. This prevents both multicast/broadcast and unicast SM-to-SM communication.  Enable Option 2 - Forward SM destined packets upstream. This not only prevents multicast/broadcast and unicast SM-to-SM communication but also sends the packets, which otherwise may have been handled SM to SM, through the Ethernet port of the AP. In the CMM and the CMM4, SM isolation treatment is the result of how to manage the port-based VLAN feature of the embedded switch, where all traffic can be switched from any AP to a specified uplink port. However, this is not packet level switching. It is not based on VLAN IDs. Filtering management through Ethernet Configure the SM to disallow any device that is connected to its Ethernet port from accessing the IP address of the SM. If the Ethernet Access Control parameter is set to Enabled, then:  No attempt to access the SM management interface (by http, SNMP, ftp, or tftp) through Ethernet is granted.  Any attempt to access the SM management interface over the air (by IP address, presuming that LAN1 Network Interface Configuration, Network Accessibility is set to Public, or by link from the Session Status or Remote Subscribers tab in the AP) is unaffected.

Chapter 3: System planning Security planning Page 3-50 Allowing management from only specified IP addresses The Security sub-menu of the Configuration web page in the AP/BHM and SM/BHS includes the IP Access Control parameter. Specify one, two, or three IP addresses that must be allowed to access the management interface (by HTTP, SNMP, FTP or TFTP). If the selection is:  IP Access Filtering Disabled, then management access is allowed from any IP address, even if the Allowed Source IP 1 to 3 parameters are populated.  IP Access Filtering Enabled, and specify at least one address in the Allowed Source IP 1 to 3 parameter, then management access is limited to the specified address(es). Configuring management IP by DHCP The Configuration > IP web page of every radio contains a LAN1 Network Interface Configuration, DHCP State parameter that, if enabled, causes the IP configuration (IP address, subnet mask, and gateway IP address) to be obtained through DHCP instead of the values of those individual parameters. The setting of this DHCP state parameter is also viewable, but is not settable, in the Network Interface tab of the Home page. In the SM/BHS, this parameter is settable  in the NAT tab of the Configuration web page, but only if NAT is enabled.  in the IP tab of the Configuration web page, but only if the Network Accessibility parameter in the IP tab is set to Public. DHCP option 81 The DHCP server can be used to register and update the pointer (PTR) and host (A) DNS resource records on behalf of its DHCP-enabled clients. The DHCP option 81 permits the client to provide its fully qualified domain name (FQDN) as well as instructions to the DHCP server on how it would like the server to process DNS dynamic updates (if any) on its behalf. The hostname is poplulated as SiteName.DomainName depending upon following conditions:  If Sitename is default i.e. No Site Name , mac address will be used instead.  The SiteName should only be a-z | A-Z | 0-9 and period(.) and dash(-).  The domain name part should not start or end with dash (-).  The underscore or space in domain name part will be converted to dash(-), anything else apart from valid characters will be skipped.

Chapter 3: System planning Security planning Page 3-51 Controlling PPPoE PADI Downlink Forwarding The AP supports the control of forwarding of PPPoE PADI (PPPoE Active Discovery Initiation) packets. This forwarding is configured on the AP GUI Configuration > Radio page by parameter PPPoE PADI Downlink Forwarding. When set to “Enabled”, the AP allows downstream and upstream transmission of PPPoE PADI packets. When set to “Disabled”, the AP does NOT allow PPPoE PADI packets to be sent out of the AP RF interface (downstream) but will allow PPPoE PADI packets to enter the RF interface (upstream) and exit the Ethernet interface.

Chapter 3: System planning Remote AP Deployment Page 3-52 Remote AP Deployment In cases where the subscriber population is widely distributed, or conditions such as geography restrict network deployment, you can add a Remote AP to:  provide high-throughput service to near LoS business subscribers.  reach around obstructions or penetrate foliage with non-LoS throughput.  reach new, especially widely distributed, residential subscribers with broadband service.  pass sync to an additional RF hop. In the remote AP configuration, a remote AP is co-located with an SM. The remote AP distributes the signal to SMs that are logically behind the co-located SM. A remote AP deployment is illustrated in Figure 56. Figure 56 Remote AP deployment The co-located SM receives data in one channel, and the remote AP must redistribute the data in a different channel. The two channels need to have a frequency gap equal to at least two times the used channel bandwidth. Base your selection of frequency band ranges on regulatory restrictions, environmental conditions, and throughput requirements. Note Each relay hop (additional daisy-chained remote AP) adds approximately 5-7 msec round trip latency.

Chapter 3: System planning Remote AP Deployment Page 3-53 Remote AP (RAP) Performance The performance of a remote AP is identical to the AP performance in cluster. Throughputs, ranges, and antenna coverage are identical. As with all equipment operating in the unlicensed spectrum, Cambium strongly recommends that you perform site surveys before you add network elements. These will indicate that spectrum is available in the area where you want to grow. Keep in mind that:  non-LoS ranges heavily depend on environmental conditions.  in most regions, not all frequencies are available.  your deployments must be consistent with local regulatory restrictions. Example Use Case for RF Obstructions A remote AP can be used to provide last-mile access to a community where RF obstructions prevent SMs from communicating with the higher-level AP in cluster. For example, you may be able to use 900 MHz for the last mile between a remote AP and the outlying SMs where these subscribers cannot form good links to a higher-level 5 GHz AP. In this case, the ability of the 900-MHz wavelength to be effective around foliage at short range solves the foliage penetration problem. An example of this use case is shown in Figure 57. In this example, the 5 GHz AP is a PMP 450i AP in the 5.8 GHz band operating on a 20 MHz channel with a 2.5 ms frame; the SMs are 5 GHz PMP 450 integrated SMs. The SM connected to the remote AP is a PMP 450i SM. The remote AP is a PMP 450i AP in the 900 MHz band, also operating in a 20 MHz channel with a 2.5 ms frame; the SMs are 900 MHz PMP 450 connectorized SMs using the Cambium 23 dBi gain antenna.

Chapter 3: System planning Remote AP Deployment Page 3-54 Figure 57 Example for 900-MHz remote AP behind 5 GHz SM The 5 GHz modules provide a sustained aggregate throughput of up to 126 Mbps to the sector. One of the SMs in the sector is wired to a 900-MHz remote AP, which provides NLoS sustained aggregate throughput2 of:  126 Mbps to 900-MHz SMs up to 4 miles away in the sector.  94 Mbps to 900-MHz SMs between 4 and 10 miles away in the sector. Example Use Case for Passing Sync All radios support the remote AP functionality. The BHS and the SM can reliably pass the sync pulse, and the BHM and AP can reliably receive it. However, not all devices are compatible with all other devices. The following table shows which SMs can be connected to which APs. Devices PMP 450 AP/BHM PMP 450i AP/BHM PMP 450m APPMP 450 SM/BHS X PMP 450i SM/BHS X X Examples of passing sync over cable are shown under Passing Sync in an Additional Hop on page 3-57. 2 NLoS ranges depend on environmental conditions. Your results may vary from these.

Chapter 3: System planning Remote AP Deployment Page 3-55 For PMP 450, the sync is passed in a cable that connects Pins 1 and 6 of the RJ-11 timing ports of the two modules. For PMP 450i/450m the sync is passed in a cable that connects Pins7 and 8 of the RJ-45 timing ports of the two modules. When connecting modules in this way, make sure the AP and SM are properly configured, as described in the Wiring to Extend Network Sync. Physical Connections Involving the Remote AP The SM to which a remote AP is connected to can be either an SM that serves a customer or an SM that simply serves as a relay. If the SM serves a customer, wire the remote AP to the SM as shown in Figure 58. Figure 58 Remote AP wired to SM that also serves a customer If the SM simply serves as a relay, you must use a straight-through RJ-45 female-to-female coupler and wire the SM to the remote AP as shown in Figure 59.

Chapter 3: System planning Remote AP Deployment Page 3-57 Passing Sync signal Passing Sync in a Single Hop Network sync can be passed in a single hop in the following network designs:  Design 1 o A CMM provides sync to a co-located AP. o This AP sends the sync over the air to SMs.  Design 2 o A CMM provides sync to a co-located BH timing master. o This BH timing master sends the sync over the air to a BH timing slave. Passing Sync in an Additional Hop Network sync can be extended by one additional link in any of the following network designs: Note In each of these following designs, Link 2 is not on the same frequency band as Link 4. (For example, Link 2 may be a 5.2 GHz link while Link 4 is a 5.7 or 2.4 GHz link.)  Design 3 o A CMM provides sync to a co-located AP. o This AP sends the sync over the air to an SM. o This SM delivers the sync to a co-located AP. o This AP passes the sync in the additional link over the air to SMs. This design is illustrated in Figure 60. Figure 60 Additional link to extend network sync, Design 3  Design 4

Chapter 3: System planning Remote AP Deployment Page 3-58 o A CMM provides sync to a co-located AP. o This AP sends the sync over the air to an SM. o This SM delivers the sync to a co-located BHM. o This BHM passes the sync in the additional link over the air to a BHS. This design is illustrated in Figure 61. Figure 61 Additional link to extend network sync, Design 4

Chapter 3: System planning Remote AP Deployment Page 3-59  Design 5 o A CMM provides sync to a co-located BHM or the BHM generates timing. o This BHM sends the sync over the air to a BHS. o This BHS delivers the sync to a co-located AP. This AP passes the sync in the additional link over the air to SMs. This design is illustrated in Figure 62. Figure 62 Additional link to extend network sync, Design 5 Wiring and configuration information for this sync extension is described under Wiring to Extend Network Sync on page 3-60.

Chapter 3: System planning Remote AP Deployment Page 3-60 Wiring to Extend Network Sync The following procedure can be used to extend network sync by one additional hop, as described under Passing Sync in an Additional Hop on page 3-57. When a co-located module receives sync over the air, the co-located modules can be wired to pass the sync as follows: 1. Connect the GPS Utility ports of the co-located modules using a sync cable with RJ-11 (for 450) or RJ-45 (for 450i/450m) connectors. 2. Set the Sync Input parameter on the Configuration page of the co-located AP or BH timing master to AutoSync. 3. Set the Device Type parameter on the Configuration page of the co-located AP or BH timing master to Remote. 4. Set the Sync Output to Aux Port parameter on the Configuration page of the co-located AP or BH timing master to Disabled. 5. Set the UGPS Power parameter on the Configuration page of the co-located AP or BH timing master to Disabled. 6. Set the Frame Timing Pulse Gated parameter on the Configuration page of the co-located SM or BH timing slave to Enable. Note This setting prevents interference in the event that the SM or BH timing slave loses sync. Figure 63 Co-located AP or BH timing master Sync Setting configuration

See the ICNIRP web site at http://www.icnirp.de/ and Guidelines for Limiting Exposure to Time-Varying Electric, Magnetic, and Electromagnetic Fields. Power density exposure limit Install the radios for the 450 Platform Family of wireless solutions so as to provide and maintain the minimum separation distances from all persons. The applicable FCC power density exposure limit for RF energy in the 4.9, 5.4 and 5.8 GHz frequency bands is 10 W/m2 and in 900 MHz frequency band is 6 W/m2. For more information, see Human exposure to radio frequency energy on page 4-22. The applicable ISEDC power density exposure limit for RF energy in unlicensed bands is 0.02619 * (f^(0.6834)), where f is the lowest frequency of the supported band. For licensed bands, the power density exposure limit is 0.6455 * (f^(0.5)), where f is the lowest frequency of the supported band.

Chapter 4: Legal and regulatory information Compliance with safety standards Page 4-24 Calculation of power density The following calculation is based on the ANSI IEEE C95.1-1991 method, as that provides a worst case analysis. Details of the assessment to EN50383:2002 can be provided, if required. Peak power density in the far field of a radio frequency point source is calculated as follows: Where: Is: S power density in W/m2 P maximum average transmit power capability of the radio, in W G total Tx gain as a factor, converted from dB d distance from point source, in m Rearranging terms to solve for distance yields: Calculated distances and power compliance margins Table 88 and Table 89 shows calculated minimum separation distances, recommended distances and resulting margins for each frequency band and antenna combination for the USA and Canada. These are conservative distances that include compliance margins. At these and greater separation distances, the power density from the RF field is below generally accepted limits for the general population. 450 Platform Family ODU adheres to all applicable EIRP limits for transmit power when operating in MIMO mode. Separation distances and compliance margins include compensation for both transmitters. Explanation of terms used in Table 88 and Table 89: P burst – maximum average transmit power during transmit burst (Watt) P – maximum average transmit power of the radio (Watt) G – total transmit gain as a factor, converted from dB S – power density (Watt/m2) d – minimum safe separation distance from point source (meters) 24.dGPSSGPd.4.

Chapter 4: Legal and regulatory information Compliance with safety standards Page 4-32 Note Gain of antenna in dBi = 10 * log(G). The regulations require that the power used for the calculations is the maximum power in the transmit burst subject to allowance for source-based time-averaging. At 5.4 GHz and EU 5.8 GHz, the products are generally limited to a fixed EIRP which can be achieved with the Integrated Antenna. The calculations above assume that the maximum EIRP allowed by the regulations is being transmitted. Remarque Gain de l'antenne en dBi = 10 * log(G). Les règlements exigent que la puissance utilisée pour les calculs soit la puissance maximale de la rafale de transmission soumis à une réduction pour prendre en compte le rapport cyclique pour les signaux modulés dans le temps. Pour une opération dans la CEE dans les bandes 5,4 GHz et 5,8 GHz, les produits sont généralement limités à une PIRE qui peut être atteinte avec l'antenne intégrée. Les calculs ci-dessus supposent que la PIRE maximale autorisée par la réglementation est atteinte. Note If there are no EIRP limits in the country of deployment, use the distance calculations for FCC 5.8 GHz for all frequency bands. At FCC 5.8 GHz, for antennas between 0.6m (2ft) and 1.8m (6ft), alter the distance proportionally to the antenna gain. Remarque Si aucune limite de PIRE existe pour le pays de déploiement, utilisez les calculs de distance pour FCC 5,8 GHz pour toutes les bandes de fréquence. Pour la band FCC 5,8 GHz et les antennes entre 0,6 m (2 pieds) et 1,8 m (6 pieds), modifier la distance proportionnellement au gain de l'antenne.

Page 5-1 Chapter 5: Preparing for installation This chapter describes how to stage and test the hardware for a 450 Platform network. This chapter is arranged as follows:  Safety on page 5-2: Describes the precautions to be observed and checks to be performed before proceeding with the installation  Preparing for installation on page 5-5: Describes the pre-configuration procedure before proceed with installation.  Testing system components on page 5-7: Describes the procedures for unpacking and performing and initial staging of the 450 Platform Family ODU.  Configuring Link for Test on page 5-16: Describes the procedures for testing the equipment’s radio links.

Chapter 5: Preparing for installation Safety Page 5-2 Safety Warning To prevent loss of life or physical injury, observe the following safety guidelines. In no event shall Cambium Networks be liable for any injury or damage caused during the installation of the Cambium 450 Platform Family. Ensure that only qualified personnel install a 450 Platform link. Hazardous locations Warning When installing the PMP/PTP 450i ATEX/HAZLOC product variants in hazardous locations, follow the instructions contained in the PMP/PTP 450i Series Hazardous Location Guide (supplied in box with the products), in addition to the instructions in this user guide. Power lines Exercise extreme care when working near power lines. Working at heights Exercise extreme care when working at heights. Power supply Always use one of the Cambium 450 Platform Family power supply units (PSU) to power the ODU. Failure to use a Cambium supplied PoE could result in equipment damage and will invalidate the safety certification and may cause a safety hazard. Grounding and protective earth The Outdoor Unit (ODU) must be properly grounded to protect against lightning. It is the user’s responsibility to install the equipment in accordance with national regulations. In the USA follow the requirements of the National Electrical code NFPA 70-2005 and 780-2004 Installation of Lightning Protection Systems. In Canada, follow Section 54 of the Canadian Electrical Code. These codes describe correct installation procedures for grounding the outdoor unit, mast, lead-in wire and discharge unit, size of grounding conductors and connection requirements for grounding electrodes. Other regulations may apply in different countries and therefore it is recommended that installation of the outdoor unit be contracted to a professional installer.

Chapter 5: Preparing for installation Safety Page 5-3 Powering down before servicing Always power down and unplug the equipment before servicing. Primary disconnect device The ODU power supply is the primary disconnect device. External cables Safety may be compromised if outdoor rated cables are not used for connections that will be exposed to the outdoor environment. For outdoor copper Cat5e Ethernet interfaces, always use Cat5e cable that is gel-filled and shielded with copper-plated steel. RF exposure near the antenna Strong radio frequency (RF) fields will be present close to the antenna when the transmitter is on. Always turn off the power to the ODU before undertaking maintenance activities in front of the antenna. Minimum separation distances Ensure that personnel are not exposed to unsafe levels of RF energy. The units start to radiate RF energy as soon as they are powered up. Never work in front of the antenna when the ODU is powered. Install the ODUs so as to provide and maintain the minimum separation distances from all persons. For minimum separation distances, see Calculated distances and power compliance margins on page 4-24. Grounding and lightning protection requirements Ensure that the installation meets the requirements defined in Grounding and lightning protection on page 3-8. Grounding cable installation methods To provide effective protection against lightning induced surges, observe these requirements:  Grounding conductor runs are as short, straight and smooth as possible, with bends and curves kept to a minimum.  Grounding cables must not be installed with drip loops.

Chapter 5: Preparing for installation Safety Page 5-4  All bends must have a minimum radius of 200 mm (8 in) and a minimum angle of 90°. A diagonal run is preferable to a bend, even though it does not follow the contour or run parallel to the supporting structure.  All bends, curves and connections must be routed towards the grounding electrode system, ground rod, or ground bar.  Grounding conductors must be securely fastened.  Braided grounding conductors must not be used.  Approved bonding techniques must be used for the connection of dissimilar metals. Siting ODUs and antennas ODUs, external antennas and GPS receivers are not designed to survive direct lightning strikes. For this reason they must be installed in Zone B as defined in Lightning protection zones on page 3-9. Mounting in Zone A may put equipment, structures and life at risk. Thermal Safety The ODU enclosure may be hot to the touch when in operation. The ODU must not be operated in ambient temperatures exceeding 40°C unless mounted in a Restricted Access Location. For more information, see ODU ambient temperature limits on page 3-10. Warning Do not install the ODU in a location where the ambient temperature could exceed 40°C unless this is a Restricted Access Location as defined by EN 60950-1. Alerte L’unité externe ne doit pas être installée dans un endroit où la température ambiante est supérieure à 40C à moins que l’accès soit limité au personnel autorisé.

Chapter 5: Preparing for installation Preparing for installation Page 5-5 Preparing for installation ODU pre-configuration It is common practice to pre-configure the units during staging before site installation by performing the following tasks:  Connecting to the unit  Configuring IP and Ethernet interfaces  Upgrading the software version and using CNUT  General configuration  Configuring security  Configuring radio parameters  Setting up SNMP agent  Configuring syslog  Configuring remote access  Monitoring the Link  Configuring quality of service  Zero Touch Configuration Using DHCP Option 66  Configuring Radio via config file  Configuring a RADIUS server If the units are to be pre-configured during staging, the safety precautions below MUST be observed. Preparing personnel In no event shall Cambium Networks be liable for any injury or damage caused during the installation of the Cambium 450 Platform Family ODU. Ensure that only qualified personnel undertake the installation of a 450 Platform system. Ensure that all safety precautions are observed. Preparing inventory Perform the following inventory checks:  Check that the correct components are available, as described in Ordering the components on page 2-60.  Check the contents of all packages against their packing lists.

Chapter 5: Preparing for installation Preparing for installation Page 5-6 Preparing tools Check that following specific tools are available, in addition to general tools:  RJ45 crimp tool (it must be the correct tool for the type of RJ45 being used).  Personal Computer (PC) with 10 or 100 or 1000 BaseT Ethernet port  Web browser  Ethernet patch cables

Chapter 5: Preparing for installation Testing system components Page 5-7 Testing system components The best practice is to connect all components—AP/BHM, SMs/BHS, GPS antenna (if applicable) and CMM (if applicable)—in a test setting and initially configure and verify them before deploying them to an installation. In this way, any configuration issues are worked out before going on-site, on a tower, in the weather, where the discovery of configuration issues or marginal hardware is more problematic and work-flow affecting. Unpacking Components When a delivery arrives, inspect all packages immediately for damages. Carefully unpack the equipment, verify that all the components have arrived as per order and are in good condition. Save all packaging materials for equipment transportation to the installation site. Preparing the ODU After the equipment is unpacked, the units may be configured for staging tests. Use either of two methods to configure an AP/BHM:  Use the Quick Start feature of the product (via GUI menu Quick Start)  Manually set each parameter After changing configuration parameters on a GUI web page:  Before you leave a web page, click the Save button to save the change(s)  After making change(s) on multiple web pages, click the Reboot button to reboot the module and implement the change(s) Configuring the Computing Device for Test If the computer is configured for Dynamic Host Configuration Protocol (DHCP), disconnect the computer from the network. If the computer is instead configured for static IP addressing  Set the static address in the 169.254 network  Set the subnet mask to 255.255.0.0. For detailed instructions, see section Configuring the management PC on page 5-16.

Chapter 5: Preparing for installation Testing system components Page 5-8 Factory default Configuration From the factory, the APs/BHMs and SMs/BHSs are all configured to not transmit on any frequency. This configuration ensures that equipment operators do not accidentally turn on an unsynchronized module. Site synchronization of modules is required because  modules: o cannot transmit and receive signals at the same time. o use TDD (Time Division Duplexing) to distribute signal access of the downlink and uplink frames.  when one module transmits while an unintended module nearby receives signal, the transmitting module may interfere with or desense the receiving module. In this context, interference is self-interference (within the same network). ODU interfaces See section 450 Platform Family interfaces on page 2-7 ODU diagnostic LEDs See section AP/BHM LEDs on page 2-15. See section SM/BHS LEDs on page 2-17. Recommended Tools for Installation The following tools may be needed for installation: Table 93 Tools for PMP and PTP 450 Platform ODU installation Equipment to Be Installed Tools Required AP or BHM  3 mm Allen Wrench Used for connecting the antenna mating bracket to the rear of the AP housing  Crescent Wrench Pair Used for tightening cable glands  Self-amalgamating and PVC Tape Used for weatherproofing N-type connections AP or BHM or BHS Antenna  13 mm Spanner Wrench (or Ratchet Spanner Wrench) Pair Used for connecting the antenna (sector or omni for AP, or directional for BH)base to the pole/mast mounting bracket  Self-amalgamating and PVC Tape Used for weatherproofing N-type connections  N-type Torque Wrench (not required but recommended) Used for assuring proper tightening of N-type connectors terminating the RF cables

Chapter 5: Preparing for installation Testing system components Page 5-9 Equipment to Be Installed Tools Required SM  Wrench/driver (depending on operator’s choice of clamps) Used for tightening clamps to the pole  Alignment tone adapter / headset Used for aligning the SM to the AP Universal Global Positioning System  Philips Screwdriver Used for attaching the UGPS unit to the pole/mast mounting bracket  13mm Spanner Wrench (or Ratchet Spanner Wrench) Used for connecting the mounting bracket’s U-bolt to the antenna or mast Cabling  Electrician’s Scissors or Wire Cutters Used for cutting wire to length  RJ-11/RJ-45 Crimping Tool Used for stripping RJ-11/RJ-45 cables and for terminating cable ends  Cable Testing Device Used to ensure that cables are properly constructed Standards for Wiring Modules automatically sense whether the Ethernet cable in a connection is wired as straight-through or crossover. Operators may use either straight-through or crossover cable to connect a network interface card (NIC), hub, router, or switch to these modules. This guide follows the EIA/TIA-568B colour code standard.

Chapter 5: Preparing for installation Testing system components Page 5-10 Best Practices for Cabling The following practices are essential to the reliability and longevity of cabled connections:  Use only shielded cables to resist interference.  For vertical runs, provide cable support and strain relief.  Include a 2-ft (0.6-m) service loop on each end of the cable to allow for thermal expansion and contraction and to facilitate terminating the cable again when needed.  Include a drip loop to shed water so that most of the water does not reach the connector at the device.  Properly crimp all connectors.  Use dielectric grease on all connectors to resist corrosion.  Use only shielded connectors to resist interference and corrosion. Wiring Connectors The following diagrams correlate pins to wire colors and illustrate crossovers where applicable. Pin 1, relative to the lock tab on the connector of a straight-through cable is located as shown below. Figure 64 Pin 1 location

Chapter 6: Installation Mount the ODU, LPU and surge suppressor Page 6-12 PMP/PTP 450 Series The PMP/PTP 450 Series uses 600SSH Surge Suppressor. The inside of the surge suppressor is shown in Figure 71. Caution The PMP 450 SM 900 MHz is based off of the 450 Series, be sure to use a 600SS to protect this radio type. Figure 71 600SSH Surge Suppressor – inside Key to Callouts 600SSH 1 Holes—for mounting the Surge Suppressor to a flat surface (such as an outside wall). The distance between centers is 4.25 inches (108 mm). 2 RJ-45 connectors—One side (neither side is better than the other for this purpose) connects to the product (AP, SM, AC Adapter, or cluster management module). The other connects to the drop cable. 3 Ground post and washer—use heavy gauge (10 AWG or 6 mm2) copper wire for connection. Refer to local electrical codes for exact specifications. 4 Ground Cable Opening—route the 10 AWG (6 mm2) ground cable through this opening. 5 CAT-5 Cable Knockouts—route the two CAT-5 cables through these openings, or alternatively through the Conduit Knockouts. 6 Conduit Knockouts—on the back of the case, near the bottom. Available for installations where cable is routed through building conduit. Note The 600SSH surge suppressor is shipped in the “isolated” position (pin 4 isolated by 68V from protective earth). If packet error issues occur over the Ethernet link (verify by pinging the device through the 600SSH), configure the 600SSH to “grounded” position (by moving the 600SSH switch from “isolated” to “ground”) to avoid ground loops that may be present in the system. The mounting procedure for the Surge Suppressor for PMP/PTP 450 Series is as follows: 1 Remove the cover of the 600SSH Surge Suppressor.

Chapter 6: Installation Mount the ODU, LPU and surge suppressor Page 6-13 2 With the cable openings facing downward, mount the 600SSH to the outside of the subscriber premises, as close to the point where the Ethernet cable penetrates the residence or building as possible, and as close to the grounding system (Protective Earth) as possible. 3 Wrap an AWG 10 (or 6mm2) copper wire around the Ground post of the 600SSH. 4 Tighten the Ground post locking nut in the 600SSH onto the copper wire. 5 Securely connect the copper wire to the grounding system (Protective Earth) according to applicable regulations. 6 Using diagonal cutters or long nose pliers, remove the knockouts that cover the cable openings to the 600SSH. 7 Pack both of the surge suppressor Ethernet jacks with dielectric grease. 8 Wrap a splice loop in the loose end of the Ethernet cable from the SM. 9 Connect that cable to one of the Ethernet jacks. 10 Connect an Ethernet cable to the other Ethernet jack of the 600SSH and to the power adapter. 11 Replace the cover of the 600SSH. General protection installation To adequately protect a 450 Platform Family installation, both ground bonding and transient voltage surge suppression are required. Grounding cable requirements When routing, fastening and connecting grounding cables, the following requirements must be implemented:  Grounding conductors must be run as short, straight, and smoothly as possible, with the fewest possible number of bends and curves.  Grounding cables must not be installed with drip loops.  All bends must have a minimum radius of 203 mm (8 in) and a minimum angle of 90° (Figure 72). A diagonal run is preferable to a bend, even though it does not follow the contour or run parallel to the supporting structure.  All bends, curves and connections must be routed towards the grounding electrode system, ground rod, or ground bar.  Grounding conductors must be securely fastened.  Braided grounding conductors must not be used.  Approved bonding techniques must be used for the connection of dissimilar metals.

Chapter 6: Installation Mount the ODU, LPU and surge suppressor Page 6-14 Figure 72 Grounding cable minimum bend radius and angle Caution Do not attach grounding cables to the ODU mounting bracket bolts, as this arrangement will not provide full protection.

Chapter 6: Installation Mount the ODU, LPU and surge suppressor Page 6-15 Basic requirements The following basic protection requirements must be implemented:  ODU must be in ‘Zone B’ (see Lightning protection zones on page 3-9).  ODU must be grounded to the supporting structure.  A surge suppression unit must be installed on the outside of the building.  The distance between the ODU and Gigabit Surge Suppressor should be kept to a minimum.  The drop cable must not be laid alongside a lightning air terminal.  All grounding cables must be a minimum size of 10 mm2 csa (8AWG), preferably 16 mm2 csa (6AWG), or 25 mm2 csa (4AWG). Protection requirements for a wall installation If the ODU is to be mounted on the wall of a building, then in addition to the general protection requirements (above), the following requirements must be observed:  The equipment must be lower than the top of the building or its lightning air terminal.  The building must be correctly grounded. Schematic examples of wall installations are shown in Figure 73. Figure 73 Grounding and lightning protection on wall

Chapter 6: Installation Mount the ODU, LPU and surge suppressor Page 6-16 Protection requirements for a mast or tower installation If the ODU is to be mounted on a metal tower or mast, then in addition to the general protection requirements (above), the following requirements must be observed:  The equipment must be lower than the top of the tower or its lightning air terminal.  The metal tower or mast must be correctly grounded. Schematic examples of mast or tower installations are shown in Figure 74.

Chapter 6: Installation Installing external antennas to a connectorized ODU Page 6-36 Note Use shielded cable for all infrastructure connections associated with APs, SMs, and CMMs. The environment that these modules operate in often has significant unknown or varying RF energy. Operator experience consistently indicates that the additional cost of shielded cables is more than compensated by predictable operation and reduced costs for troubleshooting and support. 1 Attach the included bracket to the rear of the AP using the (4) M5 x 7mm bolts Figure 96 Attaching bracket to the rear of the AP 2 Attach the AP to the antenna by sliding the bracket onto the bolts and tighten the (4) serrated flange nuts using a 13 mm spanner wrench.

Chapter 6: Installation Installing external antennas to a connectorized ODU Page 6-38 Attaching the PMP 450 Series AP and antenna to the mount point 1 Attach the upper bracket of the antenna to the mount point by closing the rear strap around the pole and tightening the (2) serrated flange nuts using a 13mm spanner wrench. These must be tightened evenly on the pol to avoid jumping/stripping threads. Figure 99 Attaching the AP antenna upper bracket to the pole 2 Attach the lower bracket of the antenna to the mount point by closing the rear strap around the pole and tightening the (2) serrated flange nuts using a 13mm spanner wrench. These must be tightened evenly on the pole to avoid jumping/stripping threads. Figure 100 Attaching the AP antenna lower bracket to the pole 3 Use a local map, compass, and/or GPS device as needed to determine the direction that one or more APs require to each cover the 90° sector.

Chapter 6: Installation Installing external antennas to a connectorized ODU Page 6-39 4 Choose the best mounting location for your particular application. Note Use the embedded spectrum analyzer or a commercial analyzer to evaluate the frequencies present in various locations. OFDM APs need not be mounted next to each other. They can be distributed throughout a given site. However, the 90° offset must be maintained. If you want to collocate these APs with PMP 100 Series APs of the 5.4-GHz frequency band range, plan to allow at least 25 MHz of separation between their center channels. 5 Secure a ground strap to the ground lug on the back of the AP. 6 Secure the ground strap to the pole, tower, or other trusted ground. 7 The bracket of the standard antenna has provision for measured down tilt. The recommended practice is to use one of the many radio analysis and mapping tools or on-line tools to calculate down tilt based on antenna height above the service area. The proper angle of tilt can be calculated as a factor of both the difference in elevation and the distance that the link spans. Even in this case, a plumb line and a protractor can be helpful to ensure the proper tilt. This tilt is typically minimal. The number of degrees to offset (from vertical) the mounting hardware leg of the support tube is equal to the angle of elevation from the lower module to the higher module (<B in the example provided in Figure 65).
