Spectrum management in radar avoidance mode
When the link is operating in radar avoidance mode, the Spectrum Management page
(
Figure 7-12
and
Figure 7-13
) contains the following additional information:
•
The main page title has the ‘Radar Avoidance’ suffix.
•
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.
•
Extra color coding of the interference histogram is provided (
Table 7-9
).
When operating with RTTT (Road transport and Traffic Telematics) Avoidance enabled
or other regulatory restrictions on channel usage, the page contains the following
additional information:
•
All channels marked with a ‘no entry’ symbol with their associated statistics
colored black are the prohibited channels. 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.
