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, it is recommended to only use every 3
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.
For Europe, the maximum power is 100mW, with a maximum spectral density of 10mW per
MHz; but there is no minimum occupied bandwidth requirement. However, a product that will
ship to both US/Canada and Europe must use the settings for US/Canada.
For Europe a medium access protocol is required. The transceiver module provides the
following medium access services:
