• Manufacturer Part Number: a2500r24c
• Description: Anaren Integrated Radio
• Manufacturer: Anaren Microwave

The user is encouraged to have packet transmission durations less than half the AC mains
period and implement an acknowledge/retransmit method.
Systems similar to the user’s system may also exist within range and may also be a source of
interference; some typical applications to consider are:
If the user requires specific time critical data throughput that cannot tolerate the delays of
potentially many re-transmissions, the user is encouraged to implement an environment-aware
algorithm that periodically monitors/scans the frequency band and maintain a list of “best
available” channels.
The radio modules can be used in a variety of physical layer configurations, the following
restricts the use to maintain compliance with the above referenced certification bodies.
The user is encouraged to use minimum power required to establish a link, thus minimizing
interference.
Changes or modifications to the module and/or operation outside the limits set forth below are
prohibited and could void the user’s authority to operate the modules.
Uses of these radio modules are limited to the following frequency ranges and modulation
settings. Using the radio modules outside of these limitations are prohibited and could void the
user’s authority to operate the modules. The user should use one of the register configurations
listed below.
Anaren provides register setting files for optimal performance and compliance for each of the
data rates given in the following at www.anaren.com.
Within the USA and Canada, the modules have been approved for use as digitally modulated
transmitters, for which they must have a minimum occupied bandwidth (6dB) of 500kHz. In
addition the spectral density may not exceed 8dBm/3kHz and the total output power including

o These typically use low duty cycles and are therefore easy to avoid using
o These are typically operated on a fixed channel, determined at installation time
acknowledge/retransmit methods
and can be avoided by using clear channel assessment. It may be useful to
change the channel used by the video surveillance equipment also, if possible.
