Important regulatory information
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 7-136.
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).

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

Chapter 1: Product description
Important regulatory information
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.

Wireless operation
Wireless operation
This section describes how the 450 Platform Family wireless link is operated, including modulation
modes, power control and security.
Time division duplexing
The system uses Time Division Duplexing (TDD) – one channel alternately transmits and receives
rather than using one channel for transmitting and a second channel for receiving. To accomplish
TDD, the AP/BHM must provide sync to its SM/BHS. Furthermore, collocated APs/BHMs must be
synced together – an unsynchronized AP/BHM that transmits during the receive cycle of a
collocated AP/BHM can prevent a second AP/BHM from being able to decode the signals from its
APs/BHSs. In addition, across a geographical area, APs/BHMs that can “hear” each other benefit
from using a common sync to further reduce self-interference within the network.
Modules use TDD on a common frequency to divide frames for uplink (orange) and downlink
(green) usage, as shown in the figure below.
For more information on synchronization configuration options, see GPS synchronization on page
2-35.

Wireless operation
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.
Page 1-15
Chapter 1: Product description
Wireless operation
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 percent.
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 9.

Note
MIMO-A achieves half the throughput of MIMO-B but adds a combining diversity (gain)
which enhances the link budget or availability.

Wireless operation
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 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.
MU-MIMO
Multiple-input multiple-output, or MIMO, is a range of technologies used to multiply the capacity
of a wireless connection without requiring more spectrum.
Although traditional MIMO techniques are focused on increasing the bandwidth available between
two wireless nodes, multi-user MIMO (MU-MIMO) applies these technologies to increase overall
wireless network capacity by allowing an access point to communicate wirelessly with more than
one wireless node at once.
A MU-MIMO access point features an array of antennas.. When the AP decides to communicate
with multiple nodes at the same time, it creates multiple simultaneous beams each directed to a
specific node.
Page 1-17
Chapter 1: Product description
Wireless operation
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 selfinterference 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.

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:

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.

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.
Page 1-21
Chapter 1: Product description
System management
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 reregistration. 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.

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).

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 18).
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 32). Other lengths of this
cable are available from Superior Essex.

GPS synchronization
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 22 uGPS
Note
PMP 450/450i/450m Series - APs can power up an uGPS via the Aux/Timing port.
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.
Page 2-35
Chapter 2: System hardware
GPS synchronization
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 23 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 450 Series and 450i Series are 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 24 V supplies for
redundancy.
Warning
PMP 450i Series requires different wiring between the CMM4 and device. If a PMP450
Series ODU is replaced by a PMP 450i Series and the existing drop cable needs to be
re-used, the adapter "CMM4 56 V power adapter, #N000045L001A" must be used
between the CMM4 and the existing drop cable.
Note
If only a 56 V supply is used, it cannot power up 29 V radios.

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 26 CMM4 (Cabinet with switch)
CMM4 (Cabinet without switch)
This CMM includes all of the functionality listed above but there is no switch. This provides the
network operator the flexibility to use the switch of their choice with the power and
synchronization capabilities of the CMM4.
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.
Page 2-39
Chapter 2: System hardware
GPS synchronization
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 7-88.

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 27 and Figure 28.

Installing a GPS receiver
Installing a GPS receiver
To install a GPS receiver as the timing reference source, use the following procedures:

Mounting the GPS receiver on page 2-42

Cabling the GPS Antenna on page 2-43

Installing and connecting the GPS LPU on page 2-43
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.
Mounting the GPS receiver module on the equipment building
If mounting the GPS receiver on the equipment building (Figure 33), 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 roofmounted 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.
If these requirements cannot all be met, then the module must be mounted on a metal tower or
mast.
Page 2-41
Chapter 2: System hardware
Installing a GPS receiver
Mounting the GPS receiver module on a metal tower or mast
If mounting the GPS receiver module on a metal tower or mast (Figure 34), 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

Page 2-42
Chapter 2: System hardware
Installing a GPS receiver
Procedure 1 Mounting the GPS receiver
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.
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.
Place the U-bolts (provided) around the pole as shown in Figure 28.
Slide the GPS antenna bracket onto the U-bolts.
Slide the ring washers (provided) onto the U-bolts.
Slide the lock washers (provided) onto the U-bolts.
Use the nuts (provided) to securely fasten the bracket to the U-bolts.
Please refer to the PMP Synchronization Solutions User Guide located on the Cambium website
(http://www.cambiumnetworks.com/resources/pmp-synchronization-solutions ).
Cabling the GPS Antenna

Site planning
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 power supply LED indicators accessible and cable length should not
exceed maximum recommended length; see Power supply site selection

Ability to meet the requirements specified in Grounding and lightning protection on page 3-8.

Aesthetics and planning permission issues.

Cable lengths; see ODU interfaces on page 2-24.

The effect of strong winds on the installation; see ODU wind loading on page 3-11.
Calculated distances and power compliance margin
The 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/PTP 450 Platform ODU adheres to all applicable EIRP limits for transmit power when
operating in MIMO mode. Separation distances and compliance margins include compensation for
both transmitters.
Page 3-7
Chapter 3: System planning
Site planning
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 ODU interfaces on page 2-24.
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.
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.
Page 3-8
Chapter 3: System planning
Site planning
Lightning protection zones
Use the rolling sphere method (Figure 35) 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 35 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.
Page 3-9
Chapter 3: System planning
Site planning
Site grounding system
Confirm that the site has a correctly installed grounding system on a common ground ring with
access points for grounding 450 Platform Family ODU.
If the outdoor equipment is to be installed on the roof of a high building (Figure 32), 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.
Page 3-10
Chapter 3: System planning
Site planning
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 200 mph (322 kph) for PMP/PTP 450i – all models 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 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:
“a” is the surface area in square meters, and
“V” is the wind speed in meters per second.
Force (in pounds) = 0.0042Av2
where:
“A” is the surface area in square feet, and
“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.

Drop cable grounding points
To estimate how many grounding kits are required for each drop cable, refer to the site installation
diagrams (Figure 30 , Figure 31 and Figure 32) 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 30), 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.

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 32), 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
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 10-38 to determine what
the maximum transmitted power and EIRP for PMP/PTP 450/450i Series that can be used in each of
countries and frequency band.
Caution
It is the responsibility of the user to ensure that the PMP/PTP ODU is operated in
accordance with local regulatory limits.
Note
Contact the applicable radio regulator to find out whether or not registration of the
PMP/PTP 450/450i Series 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.
Page 3-16
Chapter 3: System planning
Radio Frequency planning
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.
Page 3-17
Chapter 3: System planning
Radio Frequency planning
Obstructions in the Fresnel Zone
The Fresnel (pronounced fre∙NEL) Zone is a three-dimensional volume around the line of sight of
an antenna transmission. Objects that penetrate this area can cause the received strength of the
transmitted signal to fade. Out-of-phase reflections and absorption of the signal result in signal
cancellation.
The foliage of trees and plants in the Fresnel Zone can cause signal loss. Seasonal density,
moisture content of the foliage, and other factors such as wind may change the amount of loss.
Plan to perform frequent and regular link tests if you must transmit through foliage.
Planning for co-location
The first step to avoid interference in wireless systems is to set all AP/BHMs to receive timing from
a synchronization source (Cluster Management Module, or Universal Global Positioning System).
This ensures that the modules are in sync and start transmitting at the same time each frame.
The second step to avoid interference is to configure parameters on all AP/BHMs of the same
frequency band in proximity such that they have compatible transmit/receive ratios (all stop
transmitting each frame before any start receiving). This avoids the problem of one AP/BHM
attempting to receive the signal from a distant SM/BHS while a nearby AP/BHM transmits, which
could overpower that signal.
Note
Refer to Frame Alignment Legacy Mode parameter of Configuration > Radio >
Adavance tab for legacy product settings (See Table 121 PMP 450i AP Radio attributes
- 5 GHz on page 7-197).
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 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.

clearance zone depends on the surrounding environment and the antenna’s down tilt. If the
mast is surrounded by metal then larger clearance is required compared to an environment
where the antenna is surrounded by foliage

SMs should be spread in azimuth of AP antenna

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

Equipment Capability (dB)
Calculating Link Loss
The link loss is the total attenuation of the wireless signal between two point-to-multipoint units.
The link loss calculation is presented below:
Link Loss (dB) = Transmit power of the remote wireless unit (dBm) − Tx Cable loss
(dB) − Received power at the local unit (dBm) – Rx cable loss (dB) +
Antenna gain at the remote unit (dBi) + Antenna gain at the local unit
(dBi)
Calculating Rx Signal Level
The determinants in Rx signal level are illustrated in Figure 39.
Figure 39 Determinants in Rx signal level
Rx signal level is calculated as follows:
Rx signal level dB = Tx power − Tx cable loss + Tx antenna gain
− free space path loss + Rx antenna gain − Rx cable loss
Note
This Rx signal level calculation presumes that a clear line of sight is established
between the transmitter and receiver and that no objects encroach in the Fresnel zone.
Page 3-23
Chapter 3: System planning
Link planning
Calculating Fade Margin
Free space path loss is a major determinant in Rx (received) signal level. Rx signal level, in turn, is
a major factor in the system operating margin (fade margin), which is calculated as follows:
System operating margin (fade margin) dB = Rx signal level dB − Rx sensitivity dB
Thus, fade margin is the difference between strength of the received signal and the strength that
the receiver requires for maintaining a reliable link. A higher fade margin is characteristic of a
more reliable link.
Adaptive modulation
Adaptive modulation ensures that the highest throughput that can be achieved instantaneously
will be obtained, taking account of propagation and interference. When the link has been installed,
web pages provide information about the link loss currently measured by the equipment, both
instantaneously and averaged. The averaged value will require maximum seasonal fading to be
added, and then the radio reliability of the link can be computed.
For details of the system throughput, link loss and maximum distance for each frequency band in
all modulation modes, see Link on page 10-35.

Planning for connectorized units
Planning for connectorized units
This section describes factors to be taken into account when planning to use connectorized ODUs
with external antennas in 450 Platform Family links.
When to install connectorized units
The majority of radio links can be successfully deployed with the integrated ODU. However the
integrated units may not be sufficient in some areas, for example:

Where the path is heavily obscured by dense woodland on an NLOS link.

Where long LOS links are required.

Where there are known to be high levels of interference.
In these areas, connectorized ODUs and external antennas should be used.
Choosing external antennas
When selecting external antennas, consider the following factors:

The required antenna gain.

Ease of mounting and alignment.

Use dual-polarization antenna (as the integrated antenna).
Note
Enter the antenna gain and cable loss into the Installation Wizard, if the country
selected has an EIRP limit, the corresponding maximum transmit power will be
calculated automatically by the unit.
Calculating RF cable length (5.8 GHz FCC only)
The 5.8 GHz band FCC approval for the product is based on tests with a cable loss between the
ODU and antenna of not less than 1.2 dB. If cable loss is below 1.2 dB with a 1.3 m (4 ft) diameter
external antenna, the connectorized 450 Platform Family may exceed the maximum radiated
spurious emissions allowed under FCC 5.8 GHz rules.
Cable loss depends mainly upon cable type and length. To meet or exceed the minimum loss of
1.2 dB, use cables of the type and length specified in Table 59 (source: Times Microwave). This
data excludes connector losses.

Data network planning
Data network planning
This section describes factors to be considered when planning 450 Platform Family data networks.
Understanding addresses
A basic understanding of Internet Protocol (IP) address and subnet mask concepts is required for
engineering your IP network.
IP address
The IP address is a 32-bit binary number that has four parts (octets). This set of four octets has two
segments, depending on the class of IP address. The first segment identifies the network. The
second identifies the hosts or devices on the network. The subnet mask marks a boundary
between these two sub-addresses.
Dynamic or static addressing
For any computer to communicate with a module, the computer must be configured to either

use DHCP (Dynamic Host Configuration Protocol). In this case, when not connected to the
network, the computer derives an IP address on the 169.254 network within two minutes.

have an assigned static IP address (for example, 169.254.1.5) on the 169.254 network.
Note
If an IP address that is set in the module is not the 169.254.x.x network address, then
the network operator must assign the computer a static IP address in the same subnet.
When a DHCP server is not found
To operate on a network, a computer requires an IP address, a subnet mask, and possibly a
gateway address. Either a DHCP server automatically assigns this configuration information to a
computer on a network or an operator must input these items.
When a computer is brought on line and a DHCP server is not accessible (such as when the server
is down or the computer is not plugged into the network), Microsoft and Apple operating systems
default to an IP address of 169.254.x.x and a subnet mask of 255.255.0.0 (169.254/16, where /16
indicates that the first 16 bits of the address range are identical among all members of the subnet).
Page 3-27
Chapter 3: System planning
Data network planning
DNS Client
The DNS Client is used to resolve names of management servers within the operator’s
management domain (see Figure 40). This feature allows hostname configuration for NTP servers,
Authorization Servers, DHCP relay servers, and SNMP trap servers. Operators may choose to
either enter in the FQDN (Fully Qualified Domain Name) for the host name or to manually enter the
IP addresses of the servers.
Figure 40 Cambium networks management domain
Network Address Translation (NAT)
NAT, DHCP Server, DHCP Client and DMZ in SM
The system provides NAT (network address translation) for SMs in the following combinations of
NAT and DHCP (Dynamic Host Configuration Protocol):

NAT Disabled

NAT with DHCP Client (DHCP selected as the Connection Type of the WAN interface) and DHCP
Server

NAT with DHCP Client(DHCP selected as the Connection Type of the WAN interface)

NAT with DHCP Server

NAT without DHCP
NAT
NAT isolates devices connected to the Ethernet/wired side of a SM from being seen directly from
the wireless side of the SM. With NAT enabled, the SM has an IP address for transport traffic
(separate from its address for management), terminates transport traffic, and allows you to assign
a range of IP addresses to devices that are connected to the Ethernet/wired side of the SM.
Page 3-28
Chapter 3: System planning
Data network planning
In the Cambium system, NAT supports many protocols, including HTTP, ICMP (Internet Control
Message Protocols), and FTP (File Transfer Protocol). For virtual private network (VPN)
implementation, L2TP over IPSec (Level 2 Tunneling Protocol over IP Security) and PPTP (Point to
Point Tunneling Protocol) are supported.
DHCP
DHCP enables a device to be assigned a new IP address and TCP/IP parameters, including a default
gateway, whenever the device reboots. Thus DHCP reduces configuration time, conserves IP
addresses, and allows modules to be moved to a different network within the Cambium system.
In conjunction with the NAT features, each SM provides:

A DHCP server that assigns IP addresses to computers connected to the SM by Ethernet
protocol.

A DHCP client that receives an IP address for the SM from a network DHCP server.
DMZ
In conjunction with the NAT features, a DMZ (demilitarized zone) allows the assignment of one IP
address behind the SM for a device to logically exist outside the firewall and receive network
traffic. The first three octets of this IP address must be identical to the first three octets of the NAT
private IP address.
Developing an IP addressing scheme
Network elements are accessed through IP Version 4 (IPv4) addressing.
A proper IP addressing method is critical to the operation and security of a network.
Each module requires an IP address on the network. This IP address is for only management
purposes. For security, you must either:

Assign a non-routable IP address.

Assign a routable IP address only if a firewall is present to protect the module.
You assign an IP addresses to computers and network components by either static or dynamic IP
addressing. You will also assign the appropriate subnet mask and network gateway to each
module.
Address Resolution Protocol
As previously stated, the MAC address identifies a module in:

Communications between modules.

The data that modules store about each other.
Page 3-29
Chapter 3: System planning
Data network planning
The IP address is essential for data delivery through a router interface. Address Resolution
Protocol (ARP) correlates MAC addresses to IP addresses.
For communications to outside the network segment, ARP reads the network gateway address of
the router and translates it into the MAC address of the router. Then the communication is sent to
MAC address (physical network interface card) of the router.
For each router between the sending module and the destination, this sequence applies. The ARP
correlation is stored until the ARP cache times out.
Allocating subnets
The subnet mask is a 32-bit binary number that filters the IP address. Where a subnet mask
contains a bit set to 1, the corresponding bit in the IP address is part of the network address.
Example IP address and subnet mask
In Figure 41, the first 16 bits of the 32-bit IP address identify the network:
Figure 41 Example of IP address in Class B subnet
Octet 1
Octet 2
Octet 3
Octet 4
IP address 169.254.1.1
10101001

Subnet mask 255.255.0.0
11111111
11111111
00000000
00000000
In this example, the network address is 169.254 and 216 (65,536) hosts are addressable.
Selecting non-routable IP addresses
The factory default assignments for network elements are:

Unique MAC address

IP address of 169.254.1.1

Subnet mask of 255.255.0.0

Network gateway address of 169.254.0.0
For each radio and CMM4, assign an IP address that is both consistent with the IP addressing plan
for your network and cannot be accessed from the Internet. IP addresses within the following
ranges are not routable from the Internet, regardless of whether a firewall is configured:

10.0.0.0 – 10.255.255.255

172.16.0.0 – 172.31.255.255

192.168.0.0 – 192.168.255.255
Also, the subnet mask and network gateway for each CMM4 can be assigned.
Page 3-30
Chapter 3: System planning
Data network planning
Translation bridging
Optionally, the AP can be configured to change the source MAC address in every packet it receives
from its SMs to the MAC address of the SM/BHS that bridged the packet, before forwarding the
packet toward the public network. In this case:

Not more than 128 IP devices at any time are valid to send data to the AP from behind the SM.

SM populates the Translation Table tab of its Statistics web page, displaying the MAC address
and IP address of all the valid connected devices.

Each entry in the Translation Table is associated with the number of minutes that have elapsed
since the last packet transfer between the connected device and the SM.

If 128 are connected, and another attempts to connect:

If no Translation Table entry is older than 255 minutes, the attempt is ignored.
If an entry is older than 255 minutes, the oldest entry is removed and the attempt is
successful.
The Send Untranslated ARP parameter in the General tab of the Configuration page can be:
Disabled, so that the AP overwrites the MAC address in ARP packets before forwarding
them.
Enabled, so that the AP forwards ARP packets regardless of whether it has overwritten the
MAC address.
This is the Translation Bridging feature, which you can enable in the General page of the
Configuration web page in the AP. When this feature is disabled, the setting of the
Send Untranslated ARP parameter has no effect, because all packets are forwarded untranslated
(with the source MAC address intact). See Address Resolution Protocol on Page 3-29.
Engineering VLANs
The radios support VLAN functionality as defined in the 802.1Q (Virtual LANs) specification, except
for the following aspects of that specification:

Protocols:
Generic Attribute Registration Protocol (GARP) GARV
Spanning Tree Protocol (STP)
Multiple Spanning Tree Protocol (MSTP)
GARP Multicast Registration Protocol (GMRP)

Embedded source routing (ERIF) in the 802.1Q header

Multicast pruning

Flooding unknown unicast frames in the downlink
As an additional exception, the AP/BHM does not flood downward the unknown unicast frames to
the SM/BHS.
A VLAN configuration in Layer 2 establishes a logical group within the network. Each computer in
the VLAN, regardless of initial or eventual physical location, has access to the same data. For the
network operator, this provides flexibility in network segmentation, simpler management, and
enhanced security.

Special case VLAN numbers
This system handles special case VLAN numbers according to IEEE specifications:
Table 60 Special case VLAN IDs
VLAN Number
Purpose
Usage Constraint
These packets have 802.1p priority, but are
otherwise handled as untagged.
Must not be used as a
management VLAN.
Although not noted as special case by IEEE
specifications, these packets identify traffic
that was untagged upon ingress into the SM
and must remain untagged upon egress.
This policy is hard-coded in the AP.
Must not be used for
system VLAN traffic.
This VLAN is reserved for internal use.
Must not be used at all.
4095
SM membership in VLANs
With the supported VLAN functionality, the radios determine bridge forwarding on the basis of not
only the destination MAC address, but also the VLAN ID of the destination. This provides flexibility
in how SMs are used:

Each SM can be a member in its own VLAN.

Each SM can be in its own broadcast domain, such that only the radios that are members of
the VLAN can see broadcast and multicast traffic to and from the SM.

The network operator can define a work group of SMs, regardless of the AP(s) to which they
register.

Priority on VLANs (802.1p)
The radios can prioritize traffic based on the eight priorities described in the IEEE 802.1p
specification. When the high-priority channel is enabled on a SM, regardless of whether VLAN is
enabled on the AP for the sector, packets received with a priority of 4 through 7 in the 802.1p field
are forwarded onto the high-priority channel.
Page 3-33
Chapter 3: System planning
Data network planning
Operators may configure priority precedence as 802.1p Then Diffserv (Default) or Diffserv Then
802.1p. Since these priority precedence configurations are independent between the AP and SM,
this setting must be configured on both the AP and SM to ensure that the precedence is adhered to
by both sides of the link.
VLAN settings can also cause the module to convert received non-VLAN packets into VLAN
packets. In this case, the 802.1p priority in packets leaving the module is set to the priority
established by the DiffServ configuration.
If VLAN is enabled, immediately monitor traffic to ensure that the results are as desired. For
example, high-priority traffic may block low-priority.
Q-in-Q DVLAN (Double-VLAN) Tagging (802.1ad)
PMP and PTP modules can be configured with 802.1ad Q-in-Q DVLAN (Double-VLAN) tagging
which is a way for an operator to put an 802.1Q VLAN inside of an 802.1ad VLAN. A nested VLAN,
which is the original 802.1Q tag and a new second 802.1ad tag, allows for bridging of VLAN traffic
across a network and segregates the broadcast domains of 802.1Q VLANs. Q-in-Q can be used
with PPPoE and/or NAT.
The 802.1ad standard defines the S-VLAN as the Service Provider VLAN and the C-VLAN as the
customer VLAN. The radio software does 2 layer Q-in-Q whereby the C-VLAN is the 802.1Q tag and
the S-VLAN is the second layer Q tag as shown in Table 62.
Table 62 Q-in-Q Ethernet frame
Ethernet Header
S-VLAN EthType
0x88a8
C-VLAN EthType
0x8100
IP Data EthType 0x0800
The 802.1ad S-VLAN is the outer VLAN that is configurable on the Configuration > VLAN web page
of the AP/BHM. The Q-in-Q EtherType parameter is configured with a default EtherType of 0x88a8
in addition to four alternate EtherTypes that can be configured to aid in interoperability with
existing networks that use a different EtherType than the default.
The C-VLAN is the inner VLAN tag, which is the same as 802.1Q. As a top level concept, this
operates on the outermost tag at any given time, either “pushing” a tag on or “popping” a tag off.
This means packets will at most transition from an 802.1Q frame to an 801.ad frame (with a tag
“pushed” on) or an untagged 802.1 frame (with the tag “popped” off. Similarly, for an 802.1ad
frame, this can only transition from an 802.1ad frame to an 802.1Q frame (with the tag “popped”
off) since the radio software only supports 2 levels of tags.

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

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

Planning for SNMPv3 operation
SNMP security mode
Decide how SNMPv3 security will be configured.
MIB-based security management uses standard SNMPv3 MIBs to configure the user-based
security model and the view-based access control model. This approach provides considerable
flexibility, allowing a network operator to tailor views and security levels appropriate for different
types of user. MIB-based security management may allow a network operator to take advantage of
built-in security management capabilities of existing network managers.
Web-based security management allows an operator to configure users, security levels, privacy
and authentication protocols, and passphrases using the 450 Platform Family web-based
management interface. The capabilities supported are somewhat less flexible than those
supported using the MIB-based security management, but will be sufficient in many applications.
Selection of web-based management for SNMPv3 security disables the MIB-based security
management. 450 Platform Family does not support concurrent use of MIB-based and web-based
management of SNMPv3 security.
Web-based management of SNMPv3 security
Initial configuration of SNMPv3 security is available only to HTTP or HTTPS user accounts with
security role of Security Officer.
Identify the format used for SNMP Engine ID. The following formats are available:

MAC address (default)

5 and 32 hex characters (the hex character input is driven by RFC 3411 recommendations on
the Engine ID)
Page 3-37
Chapter 3: System planning
Security planning
Identify the user names and security roles of initial SNMPv3 users. Two security roles are
available:

Read Only

System Administrator
Identify the security level for each of the security roles. Three security levels are available:
(a) No authentication, no privacy
(b) Authentication, no privacy
(c) Authentication, privacy
If authentication is required, identify the protocol. The authentication protocol available is MD5.
If privacy will be used, identify the protocol. The privacy protocol available is cbc-des.
Managing module access by passwords
From the factory, each module has a preconfigured administrator-level account in the name root,
which initially requires no associated password. When you upgrade a module:

An account is created in the name admin.

Both admin and root inherit the password that was previously used to access the module, if:
Full Access password, if one was set.
Display-Only Access password, if one was set and no Full Access password was set.
Caution
If you use Wireless Manager, do not delete the root account from any module. If you
use a NMS that communicates with modules through SNMP, do not delete the root
account from any module unless you first can confirm that the NMS does not rely on
the root account for access to the modules.
Each module supports four or fewer user accounts, regardless of account levels. The available
levels are

ADMINISTRATOR, who has full read and write permissions. This is the level of the root and
admin users, as well as any other administrator accounts that one of them creates.

INSTALLER, who has permissions identical to those of ADMINISTRATOR except that the
installer cannot add or delete users or change the password of any other user.

TECHNICIAN, who has permissions to modify basic radio parameters and view informational
web pages.

GUEST, who has no write permissions and only a limited view of General Status tab.

Admin, Installer and Tech accounts can be configured as READ-ONLY. This will allow the
account to only see the items.
The ability to view information of General Status tab can be controlled by the "Site Information
Viewable to Guest Users" under the SNMP tab.
Page 3-38
Chapter 3: System planning
Security planning
From the factory default state, configure passwords for both the root and admin account at the
ADMINISTRATOR permission level, using the Account > Change Users Password page. (If
configure only one of these, then the other will still require no password for access into it and thus
remain a security risk.) If you are intent on configuring only one of them, delete the admin account.
The root account is the only account that CNUT uses to update the module.
After a password has been set for any ADMINISTRATOR-level account, initial access to the module
GUI opens the view of GUEST level.
Planning for RADIUS operation
Configure RADIUS where remote authentication is required for users of the web-based interface.
Remote authentication has the following advantages:

Control of passwords can be centralized.

Management of user accounts can be more sophisticated. For example; users can be prompted
by a network manager to change passwords at regular intervals. As another example,
passwords can be checked for inclusion of dictionary words and phrases.

Passwords can be updated without reconfiguring multiple network elements.

User accounts can be disabled without reconfiguring multiple network elements.
Remote authentication has one significant disadvantage in a wireless link product such as 450
Platform Family. If the wireless link is down, a unit on the remote side of the broken link may be
prevented from contacting a RADIUS Server, with the result that users are unable to access the
web-based interface.
One useful strategy would be to combine RADIUS authentication for normal operation with a
single locally-authenticated user account for emergency use.
PMP 450 Platform Family SM provides a choice of the following authentication methods:

EAP-MSCHAPv2

EAP-TTLS
Ensure that the authentication method selected in 450 Platform Family is supported by the RADIUS
server.
Filtering protocols and ports
Configure filters for specified protocols and ports from leaving the AP/BHM and SM/BHS and
entering the network. This protects the network from both intended and inadvertent packet loading
or probing by network users. By keeping the specified protocols or ports off the network, this
feature also provides a level of protection to users from each other.
Protocol and port filtering is set per AP/SM/BH. Except for filtering of SNMP ports, filtering occurs
as packets leave the AP/SM/BH.
For example, if SM is configured to filter SNMP, then SNMP packets are blocked from entering the
SM and, thereby, from interacting with the SNMP portion of the protocol stack on the SM.

Port Filtering with NAT Enabled
Where NAT is enabled on the SM/BHS, the filtering can be enabled for only the user-defined ports.
The following are examples for situations where the configure port can be filtered where NAT is
enabled:

To block a subscriber from using FTP, you can filter Ports 20 and 21 (the FTP ports) for both the
TCP and UDP protocols.

To block a subscriber from access to SNMP, you can filter Ports 161 and 162 (the SNMP ports)
for both the TCP and UDP protocols.
Note
In only the SNMP case, filtering occurs before the packet interacts with the protocol
stack.
Protocol and Port Filtering with NAT Disabled
Where NAT is disabled on the SM/BHS, the filtering can be enabled for both protocols and the
three user-defined ports. Using the check boxes on the interface, it can be either:

Allow all protocols except those that user wish to block.

Block all protocols except those that user wish to allow.
Allow or block any of the following protocols:

PPPoE (Point to Point Protocol over Ethernet)

Any or all of the following IPv4 (Internet Protocol version 4) protocols:

Any or all of the following IPv4 (Internet Protocol version 4) protocols:

other protocols and all ports.

If PPPoE, IPv4, and Uplink Broadcast are blocked, and also check the All others selection, then
only Address Resolution Protocol is not filtered.

Encrypting downlink broadcasts
An AP can be enabled to encrypt downlink broadcast packets such as the following:

ARP

NetBIOS

broadcast packets containing video data on UDP.
The encryption used is DES for a DES-configured module and AES for an AES-configured module.
Before the Encrypt Downlink Broadcast feature is enabled on the AP, air link security must be
enabled on the AP.
Isolating SMs in PMP
In an AP, SMs in the sector can be prevented from directly communicating with each other. In
CMM4, the connected APs can be prevented from directly communicating with each other, which
prevents SMs that are in different sectors of a cluster from communicating with each other.
In the AP, the SM Isolation parameter is available in the General tab of the Configuration web
page. Configure the SM Isolation feature by any of the following selections from drop-down menu:

Disable SM Isolation (the default selection). This allows full communication between SMs.

Enable Option 1 - Block SM destined packets from being forwarded. This prevents both
multicast/broadcast and unicast SM-to-SM communication.

Enable Option 2 - Forward SM destined packets upstream. This not only prevents
multicast/broadcast and unicast SM-to-SM communication but also sends the packets, which
otherwise may have been handled SM to SM, through the Ethernet port of the AP.
In the CMM and the CMM4, SM isolation treatment is the result of how to manage the port-based
VLAN feature of the embedded switch, where all traffic can be switched from any AP to a specified
uplink port. However, this is not packet level switching. It is not based on VLAN IDs.
Filtering management through Ethernet
Configure the SM to disallow any device that is connected to its Ethernet port from accessing the
IP address of the SM. If the Ethernet Access Control parameter is set to Enabled, then:

No attempt to access the SM management interface (by http, SNMP, ftp, or tftp) through
Ethernet is granted.

Any attempt to access the SM management interface over the air (by IP address, presuming
that LAN1 Network Interface Configuration, Network Accessibility is set to Public, or by link
from the Session Status or Remote Subscribers tab in the AP) is unaffected.
Page 3-43
Chapter 3: System planning
Security planning
Allowing management from only specified IP addresses
The Security sub-menu of the Configuration web page in the AP/BHM and SM/BHS includes the IP
Access Control parameter. Specify one, two, or three IP addresses that must be allowed to access
the management interface (by HTTP, SNMP, FTP or TFTP).
If the selection is:

IP Access Filtering Disabled, then management access is allowed from any IP address, even if
the Allowed Source IP 1 to 3 parameters are populated.

IP Access Filtering Enabled, and specify at least one address in the Allowed Source IP 1 to 3
parameter, then management access is limited to the specified address(es).
Configuring management IP by DHCP
The Configuration > IP web page of every radio contains a LAN1 Network Interface Configuration,
DHCP State parameter that, if enabled, causes the IP configuration (IP address, subnet mask, and
gateway IP address) to be obtained through DHCP instead of the values of those individual
parameters. The setting of this DHCP state parameter is also viewable, but is not settable, in the
Network Interface tab of the Home page.
In the SM/BHS, this parameter is settable

in the NAT tab of the Configuration web page, but only if NAT is enabled.

in the IP tab of the Configuration web page, but only if the Network Accessibility parameter in
the IP tab is set to Public.
DHCP option 81
The DHCP server can be used to register and update the pointer (PTR) and host (A) DNS resource
records on behalf of its DHCP-enabled clients.
The DHCP option 81 permits the client to provide its fully qualified domain name (FQDN) as well as
instructions to the DHCP server on how it would like the server to process DNS dynamic updates
(if any) on its behalf. The hostname is poplulated as SiteName.DomainName depending upon
following conditions:

If Sitename is default i.e. No Site Name , mac address will be used instead.

The SiteName should only be a-z | A-Z | 0-9 and period(.) and dash(-).

The domain name part should not start or end with dash (-).

The underscore or space in domain name part will be converted to dash(-), anything else apart
from valid characters will be skipped.

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

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 69 and Table 70 shows calculated minimum separation distances, recommended distances
and resulting margins for each frequency band and antenna combination for the USA and Canada.
These are conservative distances that include compliance margins. At these and greater separation
distances, the power density from the RF field is below generally accepted limits for the general
population.
450 Platform Family ODU adheres to all applicable EIRP limits for transmit power when operating
in MIMO mode. Separation distances and compliance margins include compensation for both
transmitters.
Explanation of terms used in Table 69 and Table 70:
P burst – maximum average transmit power during transmit burst (Watt)
P – maximum average transmit power of the radio (Watt)
G – total transmit gain as a factor, converted from dB
S – power density (Watt/m2)
d – minimum safe separation distance from point source (meters)

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

Brazil specific information
Brazil notification
For compliant operation in the 5.4 GHz band, the Equivalent Isotropic Radiated Power from the
integrated antenna or connectorized antenna shall not exceed 30 dBm (0.5 W).
The operator is responsible for enabling the DFS feature on any Canopy 5.4 GHz radio by setting
the Country Code to “Brazil”, including after the module is reset to factory defaults.
Important Note: This equipment operates as a secondary application, so it has no rights against
harmful interference, even if generated by similar equipment, and cannot cause harmful
interference on systems operating as primary applications.
Brazil certification numbers
The Anatel certification number for Brazil for the PMP/PTP 450i Series is 2426-15-7745.
Australia Notification
900 MHz modules must be set to transmit and receive only on center channels of 920, 922, or 923
MHz so as to stay within the ACMA approved band of 915 MHz to 928 MHz for the class license and
not interfere with other approved users.
After taking into account antenna gain (in dBi), 900 MHz modules’ transmitter output power (in
dBm) must be set to stay within the legal regulatory limit of 30 dBm (1 W) EIRP for this 900 MHz
frequency band.
Regulatory Requirements for CEPT Member States
(www.cept.org)
When operated in accordance with the instructions for use, Cambium Wireless equipment
operating in the 5.1 GHz and 5.4 GHz bands is compliant with CEPT Resolution 229 (REV. WRC-12).
Operating the 450 Platform Family in the bands 5150 to 5350 MHz and 5470 to 5725 MHz is granted
providing it is not causing interference to the existing primary services allocated to those bands.
For compliant operation in the 5250 to 5350 MHz band, the transmit power from the integrated
antenna or a connectorized antenna shall be limited to a maximum mean EIRP of 200 mW and a
maximum mean EIRP density of 10 mW/MHz in any 1 MHz band.
Page 4-33
Chapter 4: Legal and regulatory information
Compliance with radio regulations
For compliant operation in the 5470 to 5725 MHz band, the transmit power shall be restricted to a
maximum of 250 mW with a maximum mean EIRP of 1 W and a maximum mean EIRP density of
50 mW/MHz in any 1 MHz band.
For compliant operation in the bands 5 250-5 350 MHz and 5 470-5 725 MHz, the 450 Platform
Family employs transmitter power control.
For EU member states, RLAN equipment in the 5.4GHz bands is exempt from individual licensing
under Commission Recommendation 2003/203/EC. Contact the appropriate national
administrations for details on the conditions of use for the bands in question and any exceptions
that might apply. Also see www.ero.dk for further information.
Cambium Radio equipment operating in the 5470 to 5725 MHz band are categorized as “Class 1”
devices within the EU in accordance with ECC DEC(04)08 and are “CE” marked
to show compliance with the European Radio & Telecommunications Terminal Equipment
(R&TTE) directive 1999/5/EC. The relevant Declaration of Conformity can be found at
http://www.cambiumnetworks.com/support/ec_doc/ .
A European Commission decision, implemented by Member States on 31 October 2005, makes the
frequency band 5470-5725 MHz available in all EU Member States for wireless access systems.
Under this decision, the designation of Canopy 5.4GHz products become “Class 1 devices” and
these do not require notification under article 6, section 4 of the R&TTE Directive. Consequently,
these 5.4GHz products are only marked with the
any member state.

Grounding and protective earth
The Outdoor Unit (ODU) must be properly grounded to protect against lightning. It is the user’s
responsibility to install the equipment in accordance with national regulations. In the USA follow
the requirements of the National Electrical code NFPA 70-2005 and 780-2004 Installation of
Lightning Protection Systems. In Canada, follow Section 54 of the Canadian Electrical Code. These
codes describe correct installation procedures for grounding the outdoor unit, mast, lead-in wire
and discharge unit, size of grounding conductors and connection requirements for grounding
electrodes. Other regulations may apply in different countries and therefore it is recommended
that installation of the outdoor unit be contracted to a professional installer.
Powering down before servicing
Always power down and unplug the equipment before servicing.

Safety
Primary disconnect device
The ODU power supply is the primary disconnect device.
External cables
Safety may be compromised if outdoor rated cables are not used for connections that will be
exposed to the outdoor environment. For outdoor copper Cat5e Ethernet interfaces, always use
Cat5e cable that is gel-filled and shielded with copper-plated steel.
RF exposure near the antenna
Strong radio frequency (RF) fields will be present close to the antenna when the transmitter is on.
Always turn off the power to the ODU before undertaking maintenance activities in front of the
antenna.
Minimum separation distances
Ensure that personnel are not exposed to unsafe levels of RF energy. The units start to radiate RF
energy as soon as they are powered up. Never work in front of the antenna when the ODU is
powered. Install the ODUs so as to provide and maintain the minimum separation distances from
all persons. For minimum separation distances, see Calculated distances and power compliance
margins on page 4-24.
Grounding and lightning protection requirements
Ensure that the installation meets the requirements defined in Grounding and lightning protection
on page 3-8.
Grounding cable installation methods
To provide effective protection against lightning induced surges, observe these requirements:

Grounding conductor runs are as short, straight and smooth as possible, with bends and
curves kept to a minimum.

Grounding cables must not be installed with drip loops.

All bends must have a minimum radius of 200 mm (8 in) and a minimum angle of 90°. A
diagonal run is preferable to a bend, even though it does not follow the contour or run parallel
to the supporting structure.

All bends, curves and connections must be routed towards the grounding electrode system,
ground rod, or ground bar.
Page 5-3
Chapter 5: Preparing for installation
Safety

Grounding conductors must be securely fastened.

Braided grounding conductors must not be used.

Approved bonding techniques must be used for the connection of dissimilar metals.
Siting ODUs and antennas
ODUs, external antennas and GPS receivers are not designed to survive direct lightning strikes. For
this reason they must be installed in Zone B as defined in Lightning protection zones on page 3-9.
Mounting in Zone A may put equipment, structures and life at risk.
Thermal Safety
The ODU enclosure may be hot to the touch when in operation. The ODU must not be operated in
ambient temperatures exceeding 40°C unless mounted in a Restricted Access Location. For more
information, see ODU ambient temperature limits on page 3-10.
Warning
Do not install the ODU in a location where the ambient temperature could exceed 40°C
unless this is a Restricted Access Location as defined by EN 60950-1.
Alerte
L’unité externe ne doit pas être installée dans un endroit où la température ambiante
est supérieure à 40C à moins que l’accès soit limité au personnel autorisé.

Testing system components
Testing system components
The best practice is to connect all components—AP/BHM, SMs/BHS, GPS antenna (if applicable)
and CMM (if applicable)—in a test setting and initially configure and verify them before deploying
them to an installation. In this way, any configuration issues are worked out before going on-site,
on a tower, in the weather, where the discovery of configuration issues or marginal hardware is
more problematic and work-flow affecting.
Unpacking Components
When a delivery arrives, inspect all packages immediately for damages.
Carefully unpack the equipment, verify that all the components have arrived as per order and are
in good condition. Save all packaging materials for equipment transportation to the installation
site.
Preparing the ODU
After the equipment is unpacked, the units may be configured for staging tests.
Use either of two methods to configure an AP/BHM:

Use the Quick Start feature of the product (via GUI menu Quick Start)

Manually set each parameter
After changing configuration parameters on a GUI web page:

Before you leave a web page, click the Save button to save the change(s)

After making change(s) on multiple web pages, click the Reboot button to reboot the module
and implement the change(s)
Configuring the Computing Device for Test
If the computer is configured for Dynamic Host Configuration Protocol (DHCP), disconnect the
computer from the network. If the computer is instead configured for static IP addressing

Set the static address in the 169.254 network

Set the subnet mask to 255.255.0.0.
For detailed instructions, see section Configuring the management PC on page 5-15.

Factory default Configuration
From the factory, the APs/BHMs and SMs/BHSs are all configured to not transmit on any
frequency. This configuration ensures that equipment operators do not accidentally turn on an
unsynchronized module. Site synchronization of modules is required because

use TDD (Time Division Duplexing) to distribute signal access of the downlink and uplink
frames.
when one module transmits while an unintended module nearby receives signal, the
transmitting module may interfere with or desense the receiving module. In this context,
interference is self-interference (within the same network).

Standards for Wiring
Modules automatically sense whether the Ethernet cable in a connection is wired as straightthrough or crossover. Operators may use either straight-through or crossover cable to connect a
network interface card (NIC), hub, router, or switch to these modules. For a straight-through cable,
use the EIA/TIA-568B wire color-code standard on both ends. For a crossover cable, use the
EIA/TIA-568B wire color-code standard on one end, and the EIA/TIA-568A wire color-code standard
on the other end.

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

Configuring Link for Test
Configuring Link for Test
It is important to stage the AP/BHM and SM/BHS units first to verify proper registration before
deploying the modules to the site. To begin configuring the modules for test, see the sections
below:
Configuring the management PC
To configure the local management PC to communicate with the AP, SM, BHM or BHS, proceed as
follows:
Powering the AP/SM/BH for test configuration
Perform the following steps to power on the ODU.
Procedure 2 Powering the ODU
Plug one end of a CAT 5 Ethernet cable into the ODU.
Plug the Ethernet cable connector labeled To Radio into the jack in the pig tail that
hangs from the power supply.
Plug the other connector of the pig tail (this connector labeled To Computer) into
the Ethernet jack of the computing device.
Plug the power supply into an electrical outlet.
Warning
From this point until you remove power from the ODU, stay at least as
far from the AP as the minimum separation distance specified in
Minimum separation distances on page 5-3.
Power up the computing device
Start the browser in the computing device
The AP/BHM interface provides a series of web pages to configure and monitor the unit. Access
web-based interface through a computing device that is either directly connected or connected
through a network to the AP/BHM. If the computing device is not connected to a network when it is
being configured for test environment, and if the computer has used a proxy server address and
port to configure a module, then the operator may need to first disable the proxy setting in the
computer.
Page 5-15
Chapter 5: Preparing for installation
Configuring Link for Test
Perform the following procedure to toggle the computer to not use the proxy setting.
Procedure 3 Bypassing browser proxy settings to access module web pages
Launch Microsoft Internet Explorer
Select Tools, Internet Options, Connections, LAN Settings. Alternate web browser
menu selections may differ.
Uncheck the Use a proxy server box.
In the address bar of your browser, enter the IP address of the AP/BHM. (For example, enter
http://169.254.1.1 to access the AP/BHM through its default IP address). The AP/BHM
responds by opening the General Status tab of its Home page.
Logging into the web interface – AP/SM/BH
Procedure 4 Logging into the web interface
Plug one end of a CAT 5 Ethernet cable into the AP/BHM
