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 7-66.
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

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 1-17
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. The radio link
operates on a single frequency channel in each direction using TDD. The AP operates in TDMA mode to
service multiple SMs. 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 1-18
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.
Chapter 1: Product description Wireless operation
Page 1-19
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.
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
Chapter 1: Product description Wireless operation
Page 1-20
Note
MIMO-A achieves half the throughput of MIMO-B but adds a combining diversity (gain)
which enhances the link budget or availability.
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.
Chapter 1: Product description Wireless operation
Page 1-21
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.
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.

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.

• 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.

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 1-25
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.

Canopy Network Updater Tool (CNUT)
CNUT (Canopy Network Updater Tool) is the stand-alone software update tool for 450 Platform
Family ODUs. The CNUT 4.11.2 should be used for 450 Platform Family ODUs.
The Canopy Network Updater Tool has the following features:
• Automatically discovers all network elements
• HTTP and HTTPS
• Executes UDP command that initiates and terminates the Auto-update mode within APs/BHMs.
This command is both secure and convenient:
o For security, the AP/BHM accepts this command from only the IP address that specified in
the Configuration page of ODU.
o For convenience, Network Updater automatically sets this Configuration parameter in the
AP/BHM to the IP address of the Network Updater server when the server performs any of
the update commands.
• Allows you to choose among updating:
o Entire network.
o Only elements that you select.
o Only network branches that you select.
• Provides a Script Engine that you can use with any script which:
o The user can define.
o Cambium supplies.
CNUT is available at:

Radio recovery mode
The 450 Platform Family recovery mode provides a means to recover from serious configuration
errors including lost or forgotten passwords and unknown IP addresses.
The recovery procedure for 450m/450i/450b series and 450 series ODUs differ due to difference in
hardwares. This procedure for 450i/450m Series is known as Radio Recovery Console and for 450
Series is known as Default mode (or Default/Override Plug).
Radio Recovery Console – 450i, 450b and 450m Series
The Radio Recovery Console mode supports:
• Restoring factory default IP address 169.254.1.1 and password
• Boot with factory default Canopy system software settings
• Load previously installed SW images
See Radio Recovery Console– PMP/PTP 450i/450b and PMP 450m on page 9-39.
Default Mode (or Default Plug) – 450 Series
A default plug is available to provide access to a module whose password and/or IP address have
been forgotten.
This plug allows the 450 Series ODUs to be accessed using IP address 169.254.1.1 and no
password. During the override session, you can assign any new IP address and set either or both
user passwords (display-only and/or full access) as well as make other parameter changes.

SM/BHS LEDs
The SM/BHS LEDs provide different status of radio based on the operating modes. A SM/BHS in
“operating” mode registers and passes traffic normally. A SM/BHS in “aiming” mode does not
register or pass the traffic, but displays (via LED panel) the strength of received radio signals
(based on radio channel selected via Tools -> Alignment).

Operating Mode
• Scanning: If the SM/BHS is not registered to AP/BHM, then these three LEDs cycle on and off
from left to right (SYN/1, SES/2 and GPS/3).
• Ethernet Link:
o For 450m AP, the MAIN LNK + ACT/5 LED is active when the Main port link is present and
the AUX LNK + ACT/4 LED is active when the Aux port link is present.
o For 450/450i AP/BHM, the MAIN LNK/5 LED is lit continuously when the link is present.
o For 450/450i SM/BHS, the MAIN LNK/5 LED is lit continuously when the link is present.
• Data Transfer:
o For 450m AP, the MAIN LNK + ACT/5 LED flashes to indicate data transfer speed and
activity on the Main port and the AUX LNK + ACT/4 LED flashes to indicate data transfer
speed and activity on the Aux port.
o For 450/450i AP/BHM, the ACT/4 LED flashes during data transfer.
o For 450/450i SM/BHS, the ACT/4 LED flashes during data transfer.
o For 450b SM, the LNK/SPD/ACT/4 LED flashes during data transfer.
Aiming Mode
The 3 LEDs (SYN/1, SES/2, and GPS/3) are turned into a 3-position bar graph. The more LEDs that
are lit, the better the received power the module is seeing. The colors of the LEDS have no
particular meaning other than to assist is distinguishing one position from the next.

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 23).
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.

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 30 UGPS
Note
PMP 450/450i/450m Series - APs can power up a UGPS via the Aux/Timing port.
Note
PMP 450i/450b/450m Series - If two units are to get sync from the UGPS, then an
external power supply is required.
If the GPS position information is required to be visible on the web GUI, then the
UGPS power must be enabled on the AP; and it is safe to use both AP power and
external power for a single UGPS unit.

• +/- 48VDC input with green/amber LED’s for status
• Injects SYNC pulse from UGPS
• 2U / half-width rack-mount
Note
There are two different versions of the injector module (56V and 29V). You must
select the correct injector for the types of radios that you will be powering. In both
cases, the injectors use the same input power supplies or can be powered with +/-
48VDC. The output power is different and the type of SYNC signal used is different
between the two types of injectors. Systems can have 29V and 56V injectors deployed
alongside each other.

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 35 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.
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.

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 38 CMM4 (Cabinet with switch)
CMM4
(Cabinet
without
switch)
This CMM includes all 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.

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 7-18.
• 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 39 and Figure 40.

Chapter 2: System hardware Installing a GPS receiver
Page 2-57
Installing a GPS receiver
To install a GPS receiver as the timing reference source, use the following procedures:
• Mounting the GPS receiver on page 2-58
• Cabling the GPS Antenna on page 2-59
• Installing and connecting the GPS LPU on page 2-59
Caution
Prior to power-up of equipment, ensure that all cables are connected to the correct
interfaces of the CMM4 unit and the UGPS receiver module. Failure to do so may
result in damage to the equipment.
GPS receiver location
Mount the GPS receiver at a location that meets the following requirements:
• It must be possible to protect the installation as described in Grounding and lightning
protection on page 3-8.
• It must have an un-interrupted view of at least half of the southern (resp. northern) sky in the
northern (resp. southern) hemisphere. For a receiver mounted on a wall there must be no
other significant obstructions in the view of the sky.
• It must be mounted at least 1 m (3 ft), preferably 2 m (6 ft), away from other GPS receiving
equipment.
• It must not be sited in the field of radiation of co-located radio communications equipment and
should be positioned at a distance of at least 3 m (10 ft) away.
Mount the UGPS receiver on the wall of the equipment building if there is a suitable location on
the wall that can meet these requirements.
Caution
The GPS receiver is not approved for operation in locations where gas hazards exist,
as defined by HAZLOC (USA) and ATEX (Europe).
Mounting the GPS receiver module on the equipment building
If mounting the GPS receiver on the equipment building (Figure 45), select a position on the wall
that meets the following requirements:
• It must be below the roof height of the equipment building or below the height of any roof-
mounted equipment (such as air conditioning plant).
• It must be below the lightning air terminals.
• It must not project more than 600mm (24 inches) from the wall of the building.
Chapter 2: System hardware Installing a GPS receiver
Page 2-58
If these requirements cannot all be met, then the module must be mounted on a metal tower or
mast.
Mounting the GPS receiver module on a metal tower or mast
If mounting the GPS receiver module on a metal tower or mast (Figure 46), select a position that
meets the following requirements:
• It must not be mounted any higher than is necessary to receive an adequate signal from four
GPS satellites.
• It must be protected by a nearby lightning air terminal that projects farther out from the tower
than the GPS receiver module.
Mounting the GPS receiver
Mount the UGPS receiver (following manufacturer’s instructions) upon either an external wall
(Figure 45) or a metal tower or mast (Figure 46).
Figure 41 GPS antenna mounting
Chapter 2: System hardware Installing a GPS receiver
Page 2-59
Procedure 1 Mounting the GPS receiver
1
Ensure that the mounting position
• has an unobstructed view of the sky to 20º above the horizon.
• is not the highest object at the site. (The GPS antenna does not need to be
particularly high on a site, which would give it more exposure to lightning. It just
needs to have an unobstructed view of the sky.)
• is not further than 100 feet (30.4 meters) of cable from the CMM.
2
Select a pole that has an outside diameter of 1.25 to 1.5 inches (3 to 4 cm) to which
the GPS antenna bracket can be mounted.
3
Place the U-bolts (provided) around the pole as shown in Figure 43.
4
Slide the GPS antenna bracket onto the U-bolts.
5
Slide the ring washers (provided) onto the U-bolts.
6
Slide the lock washers (provided) onto the U-bolts.
7
Use the nuts (provided) to securely fasten the bracket to the U-bolts.

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 47) 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 47 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 44), 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.

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.

Drop cable grounding points
To estimate how many grounding kits are required for each drop cable, refer to the site installation
diagrams (Figure 42 , Figure 43, and Figure 44) and use the following criteria:
• The drop cable shield must be grounded near the ODU at the first point of contact between the
drop cable and the mast, tower or building.
• The drop cable shield must be grounded at the building entry point.
For mast or tower installations (Figure 42), 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 44), 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 10-50 to determine what
the maximum transmitted power and EIRP for PMP/PTP 450 Platform 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 if 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.

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 >
Advance tab for legacy product settings (See Table 142 PMP 450i AP Radio attributes -
5 GHz
on page 7-135).
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.

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.
