7.9.11 Spectrum Management Control with Radar Avoidance
When operating with Radar Avoidance enabled the following variances in operation apply:
The words “Radar Avoidance” are appended to the “Spectrum Management” title at the
top of the screen. See Figure 77 and Figure 78.
The only controls available to the master are the Interference Threshold attribute. This
has no effect on the operation of the wireless link and will only affect the generation of the
channel spectrum graphics. See Figure 77.
Extra color coding of the interference histogram is provided. See Table 16.
Whe
n operating with RTTT (Road transport and Traffic Telematics) Avoidance enabled or
other regulatory restrictions on channel usage the following variances apply:
All channels marked with a ‘no entry’ symbol with their associated statistics colored black
are the prohibited channels. See Figure 77 and Figure 78. These channels are never
used to
host the wireless link, but CAC measurements are still taken so that adjacent
channel biases can be calculated correctly and so the user can see if other equipment is
in use.
