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 .
2.4.1. USA & Canada
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
antenna gain may not exceed 1W. The following table shows configurations that are compliant
with this use and the expected performance.
In a frequency-agile implementation or an implementation with multiple systems sharing the
same location, using 2FSK or GFSK, the user is encouraged to only use even channel numbers
to avoid overlapping channels (127 channels would thus be available).
In a frequency-agile implementation or an implementation with multiple systems sharing the
same location, using MSK, the user is encouraged to only use every 3
rd
or 4
th
channel to avoid
overlapping channels (85 or 64 channels would thus be available).
It is encouraged to use a medium access technique which should include addressing of
individual transceiver nodes; and should include a combination of a clear channel assessment,
transmit and detect, or a frequency hopping method. This ensures that the un-licensed band
can be shared with other systems/applications.
