Radar avoidance

Ensure that the link can operate without using any barred channels. Where regulatory
restrictions apply to certain channels, these channels are barred. RTTT avoidance may
be necessary in all channel bandwidths. The number of channels barred is dependant
on the channel raster selected.
For example, the effect of the UK RTTT channel restrictions in the 30 MHz bandwidth
is shown in
channels are indicated by a 'No Entry' symbol displayed on the Spectrum Management
web page, see

Figure 2-1 RTTT channel avoidance example (5.8 GHz UK)

NOTE
Radar avoidance requirements in the 5.4GHz band in the EU is detailed in
specification EN 301-893 version V1.5.1 plus additional requirements shown
in the OJ of the EC and in the US in the specification FCC part 15.407. Radar
avoidance at 5.8 GHz is applicable to EU operation and the requirements are
currently as defined in EN 302 502.
