| Description | A preference priority for changing the frequency,
modulation, or channel width supporting the automatic
switching of the modulation scheme when the channel
becomes noisy.
The default priority is frequency, modulation, and
channel width. With the default preference, the
frequency is changed if there is a clean band
available. If there's no clean band available,
the modulation is changed. And if the
clean band is still not available, the bandwidth is
reduced until an acceptable band is found or a minimum
bandwidth of 200KHz. |
