3. PTP 250 User Guide
Safety and regulatory information
This section describes important safety and regulatory guidelines that must be observed by
personnel installing or operating PTP 250 equipment.
Important safety information
To prevent loss of life or physical injury, observe the safety guidelines in this
section.
Power lines
Exercise extreme care when working near power lines.
Working at heights
Exercise extreme care when working at heights.
Grounding and protective earth
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 Section 810 of the National Electric Code, ANSI/NFPA No.70-1984 (USA).
In Canada, follow Section 54 of the Canadian Electrical Code. These codes describe
correct installation procedures for grounding the outdoor unit, mast, lead-in wire and
discharge unit, size of grounding conductors and connection requirements for grounding
electrodes. Other regulations may apply in different countries and therefore it is
recommended that installation of the outdoor unit be contracted to a professional installer.
Using the correct power supply
Always use the Cambium Power over Ethernet injector unit (PoE power supply) or
Powered Indoor Unit (PIDU Plus) to power the ODU. Failure to use the correct power
supply could result in equipment damage and will invalidate the safety certification and
may cause a safety hazard.
phn-2510_003v000 (May 2012) I
4. Safety and regulatory information
Alternative DC supply
If the PTP 250 is to be powered from a DC supply (either as the primary power source or
as a backup to the AC supply), the DC supply must be input to the ODU via a PIDU (not a
PoE power supply). The DC supply must be connected to the PIDU DC IN terminals. The
DC supply must comply with the following requirements:
• The voltage and polarity is correct and is applied to the correct terminals in the PIDU.
• The power source is rated as Safety Extra Low Voltage (SELV).
• The power source is rated to supply at least 1 A continuously.
• The power source cannot provide more than the Energy Hazard Limit as defined by
IEC/EN/UL60950-1, Clause 2.5, Limited Power (The Energy Hazard Limit is 240VA).
Powering down before servicing
Always power down and unplug the equipment before servicing.
Lightning protection unit (LPU)
Do not remove the LPU printed circuit board when the LPU is connected to the power
supply, as high voltages are present.
Drop cable tester
The drop cable tester must NEVER be used at the ODU end connected to power from the
PoE power supply or PIDU. It must only be used (with a multimeter) to test a cable with
an ODU attached, not a cable with a PoE power supply or PIDU attached. This is because
the PoE power supply voltage exceeds the limit allowed in some countries for safe
handling in wet conditions and therefore may create a safety hazard.
Primary disconnect device
The main 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.
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.
II phn-2510_003v000 (May 2012)
5. PTP 250 User Guide
Minimum separation distances
Install the ODUs so as to provide and maintain the minimum separation distances from all
persons.
The minimum separation distances for each frequency variant are specified in Calculated
distances and power compliance margins on page 4-10.
Important regulatory information
The PTP 250 product is certified as an unlicensed device in frequency bands where it is not
allowed to cause interference to licensed services (called primary users of the bands).
Radar avoidance
In countries where radar systems are the primary band users, the regulators have
mandated special requirements to protect these systems from interference caused by
unlicensed devices. Unlicensed devices must detect and avoid co-channel operation with
radar systems.
The PTP 250 provides detect and avoid functionality for countries and frequency bands
requiring protection for radar systems.
Installers and users must meet all local regulatory requirements for radar detection. To
meet these requirements, users must set the correct country code during commissioning of
the the PTP 250. If this is not done, installers and users may be liable to civil and criminal
penalties.
Contact the Cambium helpdesk if more guidance is required.
phn-2510_003v000 (May 2012) III
6. Safety and regulatory information
USA and Canada specific information
The USA Federal Communications Commission (FCC) has asked 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.
In order to comply with these FCC requirements, Cambium supplies variants of the
PTP 250 for operation in the USA or Canada. These variants are only allowed to operate
in accordance with FCC/IC rules. In particular, operation of radio channels overlapping the
band 5600-5650 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.
To ensure compliance with FCC rules (KDB 443999: Interim Plans to Approve UNII
Devices Operating in the 5470 - 5725 MHz Band with Radar Detection and DFS
Capabilities), follow the instructions in Avoidance of weather radars (USA only) on page
2-5.
Other variants of the PTP 250 are available for use in the rest of the world, but these
variants are not supplied to the USA or Canada except under strict controls, when they
are needed for export and deployment outside the USA or Canada.
Specific expertise and training required for professional installers
To ensure that the PTP 250 is installed and configured in compliance with the
requirements of Industry Canada and the FCC, installers must have the radio engineering
skills and training described in this section. This is particularly important when installing
and configuring a PTP 250 system for operation in the 5.4 GHz UNII band.
Avoidance of weather radars
The installer must be familiar with the requirements in FCC KDB 443999. Essentially, the
installer must be able to:
• Access the FCC data base of weather radar location and channel frequencies.
• Use this information to correctly configure the product (using the GUI) to avoid
operation on channels that should be barred according to the guidelines that are
contained in the KDB and explained in detail in this user guide.
IV phn-2510_003v000 (May 2012)
7. PTP 250 User Guide
External antennas
When using a connectorized version of the product (as compared to the version with an
integrated antenna), the conducted transmit power must 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 the 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.
Ethernet networking skills
The installer must have the ability to configure IP addressing on a PC and to set up and
control products using a web browser interface.
Lightning protection
To protect outdoor radio installations from the impact of lightning strikes, the installer
must be familiar with the normal procedures for site selection, bonding and grounding.
Installation guidelines for the PTP 250 can be found in Chapter 2: Planning considerations
and Chapter 5: Installation.
Training
The installer needs to have basic competence in radio and IP network installation. The
specific requirements applicable to the PTP 250 should be gained by reading Chapter 5:
Installation and Chapter 6: Configuration and alignment and by performing sample set ups
at base workshop before live deployments.

30. Overview of the PTP 250 Chapter 1: Product description
Overview of the PTP 250
This section introduces the key features, typical uses, product variants and components of
the PTP 250.
Purpose
Cambium PTP 250 products are designed for Ethernet bridging over point-to-point
microwave links in the 5.4 GHz and 5.8 GHz unlicensed bands. Users must ensure that the
links comply with local operating regulations.
The PTP 250 is used to create a transparent bridge between two segments of the
operator’s network. This bridge can be treated as a virtual wired connection between two
points.
Key features
The key features of the PTP 250 include:
• Orthogonal Frequency Division Multiplexing (OFDM) modulation and Multiple-Input
Multiple-Output (MIMO) techniques.
• Wireless connections of up to 54 km (34 miles) in near line-of-sight conditions.
• High link availability, through the use of adaptive modulation techniques that
dynamically reduce the data rate in severe or adverse conditions.
• High-sensitivity antennas for improved signal recovery.
• A built-in web server for advanced management capabilities including detailed radio
signal diagnosis.
• Password control and encryption.
• Avoidance of interference from other devices: at initialization, the PTP 250 monitors
the available frequency channels to find a channel that is clear of interference.

31. PTP 250 User Guide Overview of the PTP 250
Radio bands
The PTP 250 operates in bands that offer the dual benefits of high data throughput and
good radio propagation characteristics. All PTP 250 product variants may operate in both
of the following bands:
• ETSI/RoW: 5.4 GHz (ETSI Band B) or 5.8 GHz (ETSI Band C).
• FCC/IC: 5.4 GHz or 5.8 GHz (FCC ISM band).
Some earlier product variants only operated in the 5.8 GHz band.
The wide band of spectrum available is subdivided into several channels such that multiple
systems can operate in the vicinity without causing interference to one another.
Typical deployment
The PTP 250 bridge consists of a pair of identical units, one deployed at each end of the
link. The radio link operates on a single frequency channel. One unit is configured as a
master and the other as a slave. The master unit takes responsibility for controlling the
link in both directions.
The bridge is aimed at a wide range of applications. One example is an enterprise that
needs to connect together the Local Area Network (LAN) of two or more buildings as
shown in Figure 1.

Connectorized ODU antenna interfaces
The connectorized ODU also has interfaces to connect to an external antenna (Figure 5)
via an N type connector with RF cable of type LMR100, LMR200, LMR300, LMR400 or
LMR600. The ‘V’ interface is for vertical polarization and the ‘H interface is for horizontal
polarization.
Figure 5 Connectorized ODU antenna interfaces
Mounting brackets
The ODU is supplied with a bracket for mounting it to a pole of 50mm (2”) to 75mm (3”) in
diameter.
The bracket allows for adjustment in both azimuth and elevation. The bracket may be split
to allow the pole mount section of the bracket to be mounted to the pole first. This allows
the installer to take the weight of the unit and secure it, one handed, with a single
mounting bolt.
Network connection
The network connection to the ODU is made via a 1000BaseT (Gigabit) Ethernet
connection. Power is provided to the ODU over the 1000BaseT Ethernet connection using
a standard IEEE 802.3at power supply.

40. Cabling and lightning protection Chapter 1: Product description
Cabling and lightning protection
This section describes the cabling and lightning protection components of PTP 250
installations.
The amount of surge protection required for a particular installation is dependent on
regulatory and end user requirements. The Cambium Networks system components
described below are designed to minimize the effect of lightning surges.
PTP and lightning protection
The standard ODU is fitted with surge limiting circuits and other features to minimize the
risk of damage due to nearby lightning strikes. To be fully effective, these standard
features require some additional equipment to be configured as part of the system
installation.
The PoE power supply meets the discharge specifications identified in Electromagnetic
compatibility (EMC) compliance on page 4-8 but does not provide lightning suppression.
The units are not designed to survive direct lightning strike. For this reason they
must not be installed in ‘Zone A’, as defined in Lightning protection zones on
page 2-16. Mounting in Zone A may put equipment, structures and life at risk.
Outdoor connections
The term ‘drop cable’ refers to the cable that is used for all connections that terminate
outside the building, for example, connections between the ODU, LPU and PoE power
supply.
For outdoor connections, always use Cat5e cable that is gel-filled and shielded with
copper-plated steel. This is the only type of outdoor drop cable supported in this
application.

Indoor connections
The CAT5e cable that connects the PoE power supply to the network equipment must meet
the following requirements:
• Screening: Must be either foil screen (FTP) or braided screen (STP) cable.
• Connectors: Must use screened RJ45 connectors with metal shells at both ends.
• Electrical connection: There must be a continuous electrical connection between
both screened connectors.
The connected network equipment must feature screened RJ45 connectors and must be
connected to ground, otherwise the PoE power supply will not be grounded, and this may
increase the levels of unwanted radiation from the ODU - PoE power supply cables.
Cable grounding kits
Drop cables must be grounded at the points specified in Grounding and lightning
protection on page 2-15. One cable grounding kit (Figure 8) is required for each drop cable
grounding point.

44. Wireless operation Chapter 1: Product description
Wireless operation
This section describes how PTP 250 wireless links are operated, including modulation
modes, power control and security.
Wireless Transmissions
The PTP 250 uses Time Division Duplexing (TDD) transmission, which means that a single
frequency channel is used for both Transmit and Receive. This is handled automatically by
the radio.
The PTP 250 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 all the sub-carriers is high.
The channel width of the OFDM signal is configurable to one of two values: 20 MHz or
40 MHz. The higher channel width provides greater link capacity at the expense of using
more spectrum. The lower channel width provides better receiver sensitivity and can also
be appropriate where the amount of free spectrum is limited.
Each channel is offset in center frequency from its neighboring channel by 20 MHz.
Spectrum management
At system start-up, the spectrum management feature of the PTP 250 monitors the
available wireless spectrum and directs both ends of the wireless link to operate on a
channel with a minimum level of co-channel and adjacent channel interference.
Alternatively, the user can configure the master unit to use a single channel or a sub-set of
channels.
Adaptive modulation
The PTP 250 can transport data over the wireless link using different modulation modes.
For a given channel width, each modulation mode transports data at a fixed rate. Although
the high order modulations will transport data at a much higher rate than the lower order
modulation modes, the receiver requires a much higher signal to noise ratio.
The system provides an adaptive modulation scheme where the receiver constantly
monitors the quality of the received signal and notifies the far end of the link of the
optimum modulation mode with which to transmit. In this way, optimum capacity is
achieved at all times.

45. PTP 250 User Guide Wireless operation
PTP LINKPlanner includes an estimate of mean data rate, the data rate provided by each
modulation and the percentage of time spent in each modulation mode.
MIMO
Multiple-Input Multiple-Output (MIMO) techniques provide protection against fading and
increase the probability that the receiver will decode a usable signal. When the effects of
MIMO are combined with those of OFDM techniques and a high link budget, there is a
high probability of a robust connection.
The PTP 250 transmits two signals on the same radio frequency, one of which is vertically
polarized and the other horizontally polarized. The system also has the ability to adapt
between two modes of operation:
• Dual Payload: When the radio channel conditions allow, the system will transmit two
different and parallel data streams, one on the vertical channel and one on the
horizontal channel. This doubles the capacity of the system.
• Single Payload: As the radio channel becomes more challenging, the system has the
ability to detect this and switch to a mode which transmits the same data stream on
both vertical and horizontal channels. This provides polar diversity and is another key
feature which allows the system to operate in challenging radio channels.
The switching between modes is automatically controlled by the adaptive modulation
feature described in Adaptive modulation on page 1-16.
