All Rights Reserved. pmp-0047 (June 2013) PMP 450 Planning Guide Safety and regulatory information Safety and regulatory information This section describes important safety and regulatory guidelines that must be observed by personnel installing or operating PMP 450 equipment. Important safety information To prevent loss of life or physical injury, observe the safety guidelines in this section. Power lines Exercise extreme care when working near power lines. Working at heights Exercise extreme care when working at heights. Grounding and protective earth PMP 450 units 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 Section 810 of the National Electric Code, ANSI/NFPA No.70-1984 (USA). 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. Powering down before servicing Always power down and unplug the equipment before servicing. Primary disconnect device The AP or SM unit’s 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. pmp-0047 (June 2013) Safety and regulatory information PMP 450 Planning Guide RF exposure near the antenna Radio frequency (RF) fields will be present close to the antenna when the transmitter is on. Always turn off the power to the PMP 450 unit before undertaking maintenance activities in front of the antenna. Minimum separation distances Install the AP/SM so as to provide and maintain the minimum separation distances from all persons. The minimum separation distances for each frequency variant are specified in Calculated distances and power compliance margins on page 4-12. Important regulatory information The PMP 450 product is 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). Radar avoidance In countries where radar systems are the primary band users, the regulators have mandated special requirements to protect these systems from interference caused by unlicensed devices. Unlicensed devices must detect and avoid co-channel operation with radar systems. Installers and users must meet all local regulatory requirements for radar detection. To meet these requirements, users must set the correct Country Code during commissioning of the PMP 450. If this is not done, installers and users may be liable to civil and criminal penalties. Contact the Cambium helpdesk if more guidance is required. USA and Canada specific information The USA Federal Communications Commission (FCC) has asked manufacturers to implement special features to prevent interference to radar systems that operate in the 5250-5350 and 5470-5725 MHz bands. These features must be implemented in all products able to operate outdoors in the UNII band. The use of the 5600 – 5650 MHz band is prohibited, even with detect-and-avoid functionality implemented. 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. In order to comply with these FCC requirements, Cambium supplies variants of the PMP 450 for operation in the USA or Canada. These variants are only allowed to operate with Country Codes that comply with FCC/IC rule. ii pmp-0047 (June 2013) PMP 450 Planning Guide Contents Contents PMP 450 module essential information

Purpose Cambium PMP 450 Series networks are designed for wireless point-to-multipoint links in the unlicensed 2.4 GHz, 5.4 GHz, and 5.8 GHz bands. Users must ensure that the PMP 450 Series complies with local operating regulations. The PMP 450 Series adds dramatically increased network throughput and capacity. The PMP 450 Series enables network operators to grow their business by offering more capacity for data, voice and video applications. Key features The Cambium PMP 450 Series offers the following benefits: Cambium’s highest performing point-to-multipoint solution, with up to 90 Mbps usable throughput State-of-the-art MIMO (Multi-In Multi-Out) technology Better spectral efficiency than other MIMO alternatives Efficient GPS synchronized, scheduled TDD operation for easy Access Point site deployment and performance that is consistent regardless of subscriber loading A range of cost-effective subscriber device solutions to meet the business case of any network application MIMO Matrix B: This technique provides for the ability to double the throughput of a radio transmission under proper RF conditions. Different data streams are transmitted simultaneously on two different antennas. nLOS benefits and limitations In addition to providing LOS (Line-Of-Sight) connectivity, use of OFDM technology can provide nLOS (near LineOf-Sight) connectivity and sometimes NLOS (Non-Line-Of-Sight) connectivity: 1-2 LOS: the installer can see the AP from the SM and the first Fresnel zone is clear. nLOS: the installer can see the AP from the SM, but a portion of the first Fresnel zone is blocked. NLOS: the installer cannot see the AP from the SM and a portion or even much of the first Fresnel zone is blocked, but subsequent Fresnel zones are open. pmp-0047 (June 2013) PMP 450 Planning Guide Overview of PMP 450 Figure 1 Line Of Sight Diagram Whereas multi-pathing degrades a link in some technologies (FSK, for example), OFDM can often use multipathing 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 SM or AP. However, attenuation through walls and trees is substantial for any use of the 2.4/5.4/5.8 GHz frequency bands. Even with OFDM, these products should not be expected to penetrate walls or extensive trees and foliage. Typical deployment The PMP 450 Series consists of Access Point Modules and Subscriber Modules. The radio link operates on a single frequency channel in each direction using Time Division Duplex (TDD). Applications for the PMP 450 Series include: High throughput enterprise applications nLOS video surveillance in metro areas Urban area network extension Network extension into areas with foliage Greenfield deployment The PMP 450 Series equipment may be deployed as a standalone network deployment offering a high-speed access network. pmp-0047 (June 2013) 1-3 Overview of PMP 450 Product description System components PMP 450 Access Point Access Point Module (AP): A connectorized outdoor transceiver unit containing all the radio, networking, antenna, and surge suppression electronics.

PMP and lightning protection Due to the full metallic connection to the tower or support structure through the AP antenna, grounding the AP and installing a 600SS surge suppressor at the Ethernet cable building ingress is strongly recommended. This suppresses overvoltages and overcurrents such as those caused by near-miss lightning. APs provide a grounding lug for grounding to the tower or support structure. The PMP 450 Series is not designed to survive direct lightning strikes. For this reason the unit should not be installed as the highest point in a localized area. Outdoor connections The term ‘drop cable’ refers to the cable that is used for all connections that terminate outside the building, for example, connections between the AP/SM, surge supressors (if installed), GPS receivers (if installed) and the power supply injector. The following practices are essential to the reliability and longevity of cabled connections: 1-14 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 pmp-0047 (June 2013) PMP 450 Planning Guide Wireless operation Wireless operation This section describes how the PMP 450 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 must provide sync to its SMs. Furthermore, collocated APs must be synced together – an unsynchronized AP that transmits during the receive cycle of a collocated AP can prevent a second AP from being able to decode the signals from its SMs. In addition, across a geographical area, APs 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 Figure 9. For more information on synchronization configuration options, see section Planning for co-location and using the OFDM Frame Calculator Tool on page 2-25. Figure 9 TDD frame division Time OFDM and channel bandwidth The PMP 450 Series transmits using Orthogonal Frequency Division Multiplexing (OFDM). The channel bandwidth of the OFDM signal may be configured to 5 MHz, 10 MHz or 20 MHz. pmp-0047 (June 2013) 1-15 Wireless operation Product description Link operation – Dynamic Rate Adapt PMP 450 Series products offer four levels or speeds of operation – 1x (QPSK), 2x (QPSK-MIMO-B), 4x (16QAMMIMO-B), and 6X (64QAM-MIMO-B). If received power is less due to distance between the AP and the SM or due to obstructions, or if interference affects the RF environment, the system will automatically and dynamically adjust links to the best operation level. The system chooses its operation 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 resends, and adjusts the operation rate accordingly. A normal system may have links that change levels of operation as the RF environment changes. Furthermore, the links operate independently; normal operation can have a downlink running at 6X while the uplink RF environment only supports 2x. Optimal sector utilization involves having as many links as possible running at 6x. This provides as much capacity as possible for the sector.

The radio automatically selects QPSK (Quadrature Phase Shift Keying), 16-QAM (Quadrature Amplitude Modulation), or 64QAM based on the RF environment to provide 2x, 4x, and 6x operation. MIMO Multiple-Input Multiple-Output (MIMO) techniques provide protection against fading and increase the probability that the receiver will decode 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-feature that comprises the MIMO technique utilized in the PMP 450 product is: Matrix B: This technique provides for the ability to double the throughput of a radio transmission under proper RF conditions. Different data streams are transmitted simultaneously on two different antennas. 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. 1-20 pmp-0047 (June 2013) PMP 450 Planning Guide Wireless operation Encryption The Cambium PMP 450 Series supports optional encryption for data transmitted over the wireless link. The PMP 450 Series 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 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.

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 an SM registers to an AP. 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) 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 v1 and SNMP v2c using 5 Management Information Base (MIB) files which are available for download from the Cambium Networks Support website (http://www.cambiumnetworks.com/support/pmp/software/). pmp-0047 (June 2013) 1-25 System management Product description 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. PMP 450 devices may receive NTP data from a CMM3 or CMM4 module, an NTP server configured in the system’s management network or a UGPS module. The Time Zone option is configurable on the AP’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, the offset will be set for the entire sector (SMs will be notified of the current Time Zone upon initial registration). If a Time Zone change is applied, the SMs will be notified of the change in a best effort fashion, meaning some SMs may not pick up the change until the next re-registration. Time Zone changes are noted in the Event Log of the AP and SM. An AP 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 AP may request NTP date and time information from the AP. No additional configuration (other than the AP receiving valid NTP data) is required to use the AP as an NTP server.

Planning considerations Regulatory planning This section describes how to plan PMP 450 links to conform to the regulatory restrictions that apply in the country of operation. It is the responsibility of the user to ensure that the PMP product is operated in accordance with local regulatory limits. Contact the applicable radio regulator to find out whether or not registration of the PMP network is required. Obeying Regulatory limits The local regulator may restrict frequency usage and channel width, and may limit the amount of conducted or radiated transmitter power. Some countries impose conducted power limits on products operating in the 2.4 GHz, 5.4 GHz and 5.8 GHz bands. For detailed information, see Compliance with radio regulations on page 4-15. Conforming to the limits Ensure the system is configured to conform to local regulatory requirements by setting the appropriate Country Code setting on the APs and SMs in the network. When using connectorized APs with external antennas, the regulations may require the maximum transmit power to be reduced. To ensure that regulatory requirements are met for connectorized installations, refer to Calculating maximum power level for connectorized AP units on page 2-18. 2-2 pmp-0047 (June 2013) PMP 450 Planning Guide Network migration planning Network migration planning The PMP 450 Series offers current network operators the ability to migrate to PMP 450 for expanded network capacity and capability.

AP or SM site selection When selecting a site for the AP or SM, 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 4-12. Height and location to achieve the best radio path. Ability to meet the requirements specified in Grounding and lightning protection on page 2-33. Aesthetics and planning permission issues. Cable lengths; see Maximum cable lengths on page 2-11. The effect of strong winds on the installation; see Wind loading on page 2-12. Power supply site selection When selecting a site for the AP or SM power supply, consider the following factors: Indoor location with no possibility of condensation. Availability of a mains electricity supply. Accessibility for viewing status indicator LED and connecting Ethernet cables. Cable lengths; see Maximum cable lengths on page 2-11. Maximum cable lengths When installing PMP 450 Series APs or SMs, the maximum permitted length of the shielded copper Ethernet interface cable is 330 feet (100m) from AP/SM to their associated power supplies or CMM4. When receiving synchronization signalling from a UGPS module, see table below for maximum synchronization cable lengths. pmp-0047 (June 2013) 2-11 Site planning Planning considerations Table 14 Sync cable length specification Configuration Maximum Cable Length (feet) Maximum Cable Length (meters) UGPS powered via external power source 330 100 UGPS powered via PMP 450 AP (via AP sync port) 130 40 Wind loading Ensure that the site will not be prone to excessive wind loading. Antennas and equipment mounted on towers or buildings will subject the mounting structure to significant lateral forces when there is appreciable wind. Antennas are normally specified by the amount of force (in pounds) for specific wind strengths. The magnitude of the force depends on both the wind strength and size of the antenna. Calculation of lateral force (metric) The magnitude of the lateral force can be estimated from: Force (in kilogrammes) = 0.1045aV2 Where: Is: surface area in square meters wind speed in meters per second The lateral force produced by a single PMP 450 at different wind speeds is shown in Table 15 Lateral force metric and Table 16 Lateral force - US.

Ensure that the structure to which the AP is fixed to is also capable of withstanding the prevalent wind speeds and loads. The structure and mounting brackets of the SM are capable of withstanding wind speeds up to 190 kph (118 mph). Ensure that the structure to which the SM is fixed to is also capable of withstanding the prevalent wind speeds and loads. Wind speed statistics Contact the national meteorological office for the country concerned to identify the likely wind speeds prevalent at the proposed location. Use this data to estimate the total wind loading on the support structures.

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 PMP 450 Series is designed to operate in Near-Line-of-Sight (nLOS), Non-Line-of-Sight (NLOS) and Line-ofSight (LOS) environments. An NLOS environment is one in which there is no optical line-of-sight, that is, there are obstructions between the antennas. See Figure 1 Line Of Sight Diagram. 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 SM or AP. However, attenuation through walls and trees is substantial for any use of the 5.8 GHz frequency band. Even with OFDM, these products should not be expected to penetrate walls or extensive trees and foliage.

Calculating path loss 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: L free _ space Lexcess L fade Lseasonal Lcapability Where: Is: L free _ space Free Space Path Loss (dB) Lexcess Excess Path Loss (dB) L fade Fade Margin Required (dB) Lseasonal Seasonal Fading (dB) Lcapability Equipment Capability (dB) Calculating maximum power level for connectorized AP units If a connectorized PMP 450 AP is to be installed in a country that imposes an EIRP limit in the selected band, calculate the highest setting of Maximum Power Level that will be permitted using this formula: Maximum Power Level (dBm) = Allowed EIRP (dBm) – Antenna Gain (dBi) + Cable Loss (dB) Where: Is: Maximum Power Level (dBm) the highest permissible setting of the transmitter output power, Allowed EIRP (dBm) the EIRP limit allowed by the regulations, Antenna Gain (dBi) the gain of the chosen antenna, Cable Loss (dB) the loss of the RF cable connecting the AP to the antenna. For more information on EIRP limits, see Compliance with radio regulations on page 4-15. 2-18 pmp-0047 (June 2013) PMP 450 Planning Guide Link planning Understanding Attenuation An RF signal in space is attenuated by atmospheric and other effects as a function of the distance from the initial transmission point. The further a reception point is placed from the transmission point, the weaker is the received RF signal. 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 Rx sensitivity of each module is provided at http://www.cambiumnetworks.com. The determinants in Rx signal level are illustrated in Figure 11. Figure 11 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 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. pmp-0047 (June 2013) 2-19 Analyzing the RF Environment Planning considerations 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. 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 you are planning to use. Regardless of how you measure and log or chart the results you find (through the Spectrum Analyzer in SM feature or by using a spectrum analyzer), you should do so: at various times of day. on various days of the week. periodically into the future. As new RF neighbors move in or consumer devices in your spectrum proliferate, this will keep you aware of the dynamic possibilities for interference with your network. Mapping RF Neighbor Frequencies These modules allow you to use an SM or an AP that is temporarily transformed into an SM, as a spectrum analyzer. view a graphical display that shows power level in RSSI and dBm at 5-MHz increments throughout the frequency band range, regardless of limited selections in the Custom Radio Frequency Scan Selection List parameter of the SM. select an AP channel that minimizes interference from other RF equipment. The following procedure causes the SM to drop any active RF link. If a link is dropped when the spectrum analysis begins, the link can be re-established when either a 15-minute interval has elapsed or the spectrum analyzer feature is disabled. 2-20 pmp-0047 (June 2013) PMP 450 Planning Guide Analyzing the RF Environment Analyzing the spectrum To use the built-in spectrum analyzer functionality of the SM (or AP that is temporarily configured as an SM for spectrum analysis via the AP’s GUI) proceed as follows: Procedure 3 Analyzing the spectrum Predetermine a power source and interface that will work for the SM in the area you want to analyze. Take the SM, power source, and interface device to the area. Access the Tools web page of the SM. RESULT: The Tools page opens to its Spectrum Analyzer tab. Click Enable. RESULT: The feature is enabled. Click Enable again. RESULT: The system measures RSSI and dBm for each frequency in the spectrum. Travel to another location in the area. Click Enable again. RESULT: The system provides a new measurement of RSSI and dBm for each frequency in the spectrum. Spectrum analysis mode times out 15 minutes after the mode was invoked. Repeat Steps 6 and 7 until the area has been adequately scanned and logged. As with any other data that pertains to your business, a decision today to put the data into a retrievable database may grow in value to you over time. Wherever you find the measured noise level is greater than the sensitivity of the radio that you plan to deploy, use the noise level (rather than the link budget) for your link feasibility calculations. pmp-0047 (June 2013) 2-21 Analyzing the RF Environment Planning considerations 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 for 5.4-GHz and 5.8-GHz signals. 5 inches for 2.4-GHz 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 and so overall attenuation 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. Noting Possible 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. Outof-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 though foliage. 2-22 pmp-0047 (June 2013) PMP 450 Planning Guide Analyzing the RF Environment 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.

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 APs 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 attempting to receive the signal from a distant SM while a nearby AP transmits, which could overpower that signal. The following parameters on the AP determine the transmit/receive ratio: Max Range Downlink Data percentage (reserved) Control Slots If OFDM (PMP 430, PMP 450, PTP 230) and FSK (PMP 1x0) APs of the same frequency band are in proximity, or if you want APs set to different parameters (differing in their Max Range values, for example), then you should use the Frame Calculator to identify compatible settings. The frame calculator is available on the Frame Calculator tab of the Tools web page. To use the Frame Calculator, type into the calculator various configurable parameter values for each proximal AP, and then record the resulting AP Receive Start value. Next vary the Downlink Data percentage in each calculation and iterate until the calculated AP Receive Start for all collocated APs are within 300 bit times; if possible, within 150 bit times. In Cambium Point-to-Multipoint systems, 10 bit times = 1 µs. The calculator does not use values in the module or populate its parameters. It is merely a convenience application that runs on a module. For this reason, you can use any FSK module (AP, SM, BHM, BHS) to perform FSK frame calculations for setting the parameters on an FSK AP and any OFDM module (AP, SM, BHM, BHS) to perform OFDM frame calculations for setting the parameters on an OFDM AP. IMPORTANT! APs that have slightly mismatched transmit-to-receive ratios and low levels of data traffic may see little effect on throughput. A system that was not tuned for co-location may work fine at low traffic levels, but encounter problems at higher traffic levels. The conservative practice is to tune for co-location before traffic ultimately increases. This prevents problems that occur as sectors are built. pmp-0047 (June 2013) 2-25 Analyzing the RF Environment Planning considerations Figure 14 OFDM Frame Calculator tab In the Frame Calculator tab, you may set the following parameters. Table 22 OFDM Frame Calculator tab attributes 2-26 Attribute Meaning Link Mode For AP to SM frame calculations, select Multipoint Link Platform Type AP/BHM Use the drop-down list to select the hardware series (board type) of the AP. Platform Type SM/BHS Use the drop-down list to select the hardware series (board type) of the SM. Channel Bandwidth Set this to the channel bandwidth used in the AP. Cyclic Prefix Set this to the cyclic prefix used in the AP. Max Range Set to the same value as the Max Range parameter is set in the AP(s). Air Delay This field should be left at the default of 0 ns. pmp-0047 (June 2013) PMP 450 Planning Guide Analyzing the RF Environment Attribute Meaning Downlink Data Initially set this parameter to the same value that the AP has for its Downlink Data parameter (percentage). Then, as you use the Frame Calculator tool in Procedure 4, you will vary the value in this parameter to find the proper value to write into the Downlink Data parameter of all APs in the cluster. PMP 450 Series APs offer a range of 15% to 85%, and default to 75%. The value that you set in this parameter has the following interaction with the value of the Max Range parameter (above): The default Max Range value is 5 miles and, at that distance, the maximum Downlink Data value (85% in PMP450) is functional. Control Slots Set this parameter to the value of the Control Slot parameter is set in the APs. The Calculated Frame Results display several items of interest: Table 23 OFDM Calculated Frame Results attributes Attribute Meaning Modulation The type of radio modulation used in the calculation (OFDM for PMP 450) Total Frame Bits The total number of bits used in the calculated frames Data Slots (Down/Up) This field is based on the Downlink Data setting. For example, a result within the typical range for a Downlink Data setting of 75% is 61/21, meaning 61 data slots down and 21 data slots up. Round Trip Air Delay (MaxRange) This is the roundtrip air delay in bit times for the Max Range value set in the calculator Approximate distance (MaxRange) The Max Range value used for frame calculation AP Transmit End In bit times, this is the frame position at which the AP ceases transmission. AP Receive Start In bit times, this is the frame position at which the AP is ready to receive transmission from the SM. AP Receive End In bit times, this is the frame position at which the AP will cease receiving transmission from the SM. SM Receive End In bit times, this is the frame position at which the SM will cease receiving transmission from the AP. SM Transmit Start In bit times, this is the frame position at which the SM will begin transmission. pmp-0047 (June 2013) 2-27 Selecting Sites for Network Elements Planning considerations To use the Frame Calculator to ensure that all APs are configured to transmit and receive at the same time, follow the procedure below: Procedure 4 Using the Frame Calculator Populate the OFDM Frame Calculator parameters with appropriate values as described above.

Click the Calculate button. Scroll down the tab to the Calculated Frame Results section If the recorded values of the AP Receive Start fields are within 150 bit times of each other, skip to step 10. If the recorded values of the AP Receive Start fields are not within 150 bit times of each other, modify the Downlink Data parameter until the calculated results for AP Receive Start are within 300 bit time of each other, if possible, 150 bit time. 10 Access the Radio tab in the Configuration web page of each AP in the cluster and change its Downlink Data parameter (percentage) to the last value that was used in the Frame Calculator. Selecting Sites for Network Elements The APs must be positioned 2-28 with hardware that the wind and ambient vibrations cannot flex or move. where a tower or rooftop is available or can be erected. where a grounding system is available. with lightning arrestors to transport lightning strikes away from equipment. at a proper height: o higher than the tallest points of objects immediately around them (such as trees, buildings, and tower legs). o at least 2 feet (0.6 meters) below the tallest point on the tower, pole, or roof (for lightning protection). away from high-RF energy sites (such as AM or FM stations, high-powered antennas, and live AM radio towers). in line-of-sight paths o to the SMs. o that will not be obstructed by trees as they grow or structures that are later built. pmp-0047 (June 2013) PMP 450 Planning Guide Selecting Sites for Network Elements Visual line of sight does not guarantee radio line of sight. Surveying Sites Factors to survey at potential sites include what pre-existing wireless equipment exists at the site. (Perform spectrum analysis.) whether available mounting positions exist near the lowest elevation that satisfies line of site, coverage, and other link criteria. whether you will always have the right to decide who climbs the tower to install and maintain your equipment, and whether that person or company can climb at any hour of any day. whether you will have collaborative rights and veto power to prevent interference to your equipment from wireless equipment that is installed at the site in the future. whether a pre-existing grounding system (path to Protective Earth ) exists, and what is required to establish a path to it. who is permitted to run any indoor lengths of cable. Clearing the Radio Horizon Because the surface of the earth is curved, higher module elevations are required for greater link distances. This effect can be critical to link connectivity in link spans that are greater than 8 miles (12 km). To use metric units to find the minimum height required to reach the radio horizon use the following equation: Radio horizon distance (km) = 4.12 (SQRT(h1) + SQRT(h2)) Where: Is: h1 height of the AP h2 height of the SM To use English standard units to find the angle of elevation, use the following formula: Radio horizon distance (km) = 1.42 (SQRT(h1) + SQRT(h2)) Where: Is: h1 height of the AP h2 height of the SM pmp-0047 (June 2013) 2-29 Selecting Sites for Network Elements Planning considerations Calculating the Aim Angles 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 ( VLAN web page of the AP. 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. pmp-0047 (June 2013) 2-51 Security planning Planning considerations Security planning This section describes how to plan for PMP 450 networks to operate in secure mode. Isolating APs from the Internet Ensure that the IP addresses of the APs in your 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. Managing module access by passwords Adding a user for access to a module From the factory, each module has a preconfigured administrator-level account in the name root, which initially requires no associated password. This is the same root account that you may have used for access to the module by ftp. When you upgrade a module an account is created in the name admin. both admin and root inherit the password that was previously used for access to the module: o the Full Access password, if one was set. o the Display-Only Access password, if one was set and no Full Access password was set. If you use Wireless Manager, do not delete the root account from any module. If you use an 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 2-52 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 pmp-0047 (June 2013) PMP 450 Planning Guide Security planning GUEST, who has no write permissions and only a limited view of General Status 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 tab. (If you 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. After a password has been set for any ADMINISTRATOR-level account, initial access to the module GUI opens the view of GUEST level.

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. Except for filtering of SNMP ports, filtering occurs as packets leave the AP/SM. If an 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. 2-56 pmp-0047 (June 2013) PMP 450 Planning Guide Security planning Port Filtering with NAT Enabled Where NAT is enabled on the SM, you can filter only the three user-defined ports. The following are example situations in which you can configure port filtering 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, you can filter both protocols and the three user-defined ports. Using the check boxes on the interface, you can either allow all protocols except those that you wish to block. block all protocols except those that you wish to allow. You can 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: o SMB (Network Neighborhood) o SNMP o Up to 3 user-defined ports o All other IPv4 traffic (see Figure 26) o Uplink Broadcast o ARP (Address Resolution Protocol) o All others (see Figure 26) pmp-0047 (June 2013) 2-57 Security planning Planning considerations Figure 26 Categorical protocol filtering BootP Server BootP Client IPv4 Multica st SNMP All Other IPv4 User Defined Port 1 SMB User Defined Port 2 User Defined Port 3 ARP PPPoE All Others The following are example situations in which you can configure protocol filtering where NAT is disabled: 2-58 If you block a subscriber from only PPoE and SNMP, then the subscriber retains access to all other protocols and all ports. If you block PPoE, IPv4, and Uplink Broadcast, and you also check the All others selection, then only Address Resolution Protocol is not filtered. pmp-0047 (June 2013) PMP 450 Planning Guide Security planning The ports that are filtered as a result of protocol selections in the Protocol Filtering tab of the SM are listed in Table 29.

In CMMmicro Release 2.2 or later and the CMM4, you can prevent connected APs 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. In the dropdown menu for that parameter, you can configure the SM Isolation feature by any of the following selections: Disable SM Isolation (the default selection). This allows full communication between SMs. Block SM Packets from being forwarded. This prevents both multicast/broadcast and unicast SM-to-SM communication. Block and Forward SM Packets to Backbone. This not only prevents multicast/broadcast and unicast SM-toSM communication but also sends the packets, which otherwise would have been handled SM to SM, through the Ethernet port of the AP. In the CMMmicro and the CMM4, SM isolation treatment is the result of how you choose to manage the port-based VLAN feature of the embedded switch, where you can switch all traffic from any AP to an uplink port that you specify. However, this is not packet level switching. It is not based on VLAN IDs. See the VLAN Port Configuration parameter in the dedicated user guide that supports the CMM product that you are deploying. 2-60 pmp-0047 (June 2013) PMP 450 Planning Guide Security planning Filtering management through Ethernet You can configure the SM to disallow any device that is connected to its Ethernet port from accessing the IP address of the SM. If you set the Ethernet Access Control parameter to Enabled, then no attempt to access the SM management interface (by http, SNMP, ftp, or tftp) through Ethernet can succeed. 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. Allowing management from only specified IP addresses The Security tab of the Configuration web page in the AP and SM includes the IP Access Control parameter. You can specify one, two, or three IP addresses that should be allowed to access the management interface (by HTTP, SNMP, FTP, or TFTP). If you select 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 IP tab in the Configuration 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, 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. Planning for airlink security 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. pmp-0047 (June 2013) 2-61 Security planning Planning considerations Planning for RF Telnet Access Control The RF Telnet Access feature restricts Telnet access to the AP from a device situated below a network SM (downstream from the AP). This is a security enhancement to restrict RF-interface sourced AP access specifically to the LAN1 IP address and LAN2 IP address (Radio Private Address, typically 192.168.101.[LUID]). This restriction disallows unauthorized users from running Telnet commands on the AP that can change AP configuration or modifying network-critical components such as routing and ARP tables. Forwarding Downlink PPPoE PADI packets 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 tab 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 will 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. Planning for RADIUS integration PMP 450 modules include support for the RADIUS (Remote Authentication Dial In User Service) protocol supporting Authentication, Authorization, and Accounting (AAA). RADIUS Functions RADIUS protocol support provides the following functions: 2-62 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 is not used for APs. Cambium modules support EAPTTLS and EAP-MSCHAPv2 authentication methods. SM Configuration: Configures authenticated SMs with MIR (Maximum Information Rate), CIR (Committed Information Rate), High Priority, and VLAN (Virtual LAN) parameters from the RADIUS server when an SM registers to an AP. 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) 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 Networks Wireless Manager. This accounting is not the ability to perform accounting functions on the subscriber/end user/customer account. pmp-0047 (June 2013) PMP 450 Planning Guide Security planning Framed IP allows operators to use a RADIUS server to assign management IP addressing to SM modules (framed IP address). Planning for SNMP security Canopy modules provide the following Configuration web page parameters in the SNMP tab. These govern SNMP access from the manager to the agent: Community String, which specifies the password for security between managers and the agent. Accessing Subnet, which specifies the subnet mask that allows managers to poll the agents. pmp-0047 (June 2013) 2-63 Ordering components Planning considerations Ordering components This section describes how to select components for PMP 450 Greenfield network or PMP 450 network migration.

Power density exposure limit Install the radios for the PMP 450 family of PMP wireless solutions so as to provide and maintain the minimum separation distances from all persons. The applicable power density exposure limit from the standards (see Human exposure to radio frequency energy on page 4-11) is: 10 W/m2 for RF energy in the 5.4-GHz and 5.8-GHz frequency bands. pmp-0047 (June 2013) 4-11 Compliance with safety standards Reference information 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: S P .G 4 d 2 Where: Is: power density in W/m2 maximum average transmit power capability of the radio, in W total Tx gain as a factor, converted from dB distance from point source, in m Rearranging terms to solve for distance yields: d P.G 4 .S Calculated distances and power compliance margins Table 38 shows calculated minimum separation distances, recommended distances and resulting margins for each frequency band and antenna combination. 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. PMP 450 equipment 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 38: Tx burst – maximum average transmit power in burst (Watt) P – maximum average transmit power capability of the radio (Watt) (combined transmitters) G – total transmit gain as a factor, converted from dB S – power density (W/m2) d – minimum distance from point source (meters) R – recommended distances (meters) C – compliance factor 4-12 pmp-0047 (June 2013) PMP 450 Planning Guide Compliance with safety standards Table 38 Power Compliance Margins Freq.

Changes or modifications not expressly approved by Cambium could void the user’s authority to operate the system. Type approvals This system has achieved Type Approval in various countries around the world. This means that the system has been tested against various local technical regulations and found to comply. The frequency bands in which the system operates may be ‘unlicensed’ and, in these bands, the system can be used provided it does not cause interference. The system is not guaranteed protection against interference from other products and installations.

If no radar signature is detected during this minute, the module then proceeds to normal beacon transmit mode. If it does detect a radar signature, the frequency is marked for a 30 minute non-occupancy period, and the module moves to its 1st alternate carrier frequency. The AP continues this behavior through its 2nd alternate frequency if needed and then waits until the first frequency ends the 30 minute non-occupancy period. While operating, if the AP detects a weather radar signature it marks the current carrier frequency for a 30 minute non-occupancy period and moves to check the next-in-line carrier frequency. An SM does not begin transmission until it detects a beacon from an AP. If APs are not transmitting, SMs will be silent. pmp-0047 (June 2013) 4-27 Compliance with radio regulations Reference information Europe applies the ETSI specification to both APs and SMs, while Brazil applies it only to APs. In the ETSI case, when an SM is powered on, it scans to find a Canopy beacon from a AP. If an AP is found, the SM performs a channel availability check on that frequency for 1 minute, monitoring for the radar signature, without transmitting. A DFS decision is made based on the following: If no radar pulse is detected during this 1 minute, the SM proceeds through normal steps to register to an AP. If the SM does detect radar, it locks out that frequency for 30 minutes and continues scanning other frequencies in its scan list. After an SM with DFS has seen a radar signature on a frequency and locked out that frequency, it may connect to a different AP if color codes, AP transmitting frequencies, and SM scanned frequencies support that connection. To simplify operation and ensure compliance, an SM takes on the DFS type of the AP to which it registers. For example, when an SM in Europe registers to an AP with the Country Code set to “United Kingdom”, that SM will use ETSI DFS, no matter what its Country Code is set to, even if its Country Code is set to “None”. Note, the operator should still configure the Country Code in the SM correctly, as future releases may use the Country Code for additional region-specific options. For all modules running DFS, the module displays its DFS state on its Home => General Status page as one of the following: Checking Channel Availability Remaining time n seconds, where n counts down from 60 to 1. Normal Transmit Radar Detected Stop Transmitting for n minutes, where n counts down from 30 to 1. Idle, only for SM/BHS, indicates module is scanning, but has not detected a beacon from an AP/BHM. Once it detects beacon, the SM/BHS begins a Channel Availability Check on that frequency. Regulatory Note: A PMP 450 Series AP with a Country Code set to United States will not be configurable to another Country Code by installers or end users. This is in response to FCC KDB 594280 and ensures that end users and professional installers will not have access to settings which could allow a radio to be configured to operate in a manner other than that which was specified in the FCC equipment authorization grant. Within the United States and its territories the PMP 450 Country Code is pre-configured to United States and not selectable in the Configuration, General web page. Radios sold in regions outside of the United States and its territories are required to set the Country Code to the region in which it is used. 4-28 pmp-0047 (June 2013) PMP 450 Planning Guide Compliance with radio regulations FCC compliance testing With GPS synchronization installed, the system has been tested for compliance to US (FCC) specifications. It has been shown to comply with the limits for emitted spurious radiation for a Class B digital device, pursuant to Part 15 of the FCC Rules in the USA. These limits have been designed to provide reasonable protection against harmful interference. However the equipment can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to other radio communications. There is no guarantee that interference will not occur in a particular installation. A Class B Digital Device is a device that is marketed for use in a residential environment, notwithstanding use in commercial, business and industrial environments. Notwithstanding that Cambium has designed (and qualified) the PMP 450 products to generally meet the Class B requirement to minimize the potential for interference, the PMP 450 product range is not marketed for use in a residential environment.
