Radar Avoidance and Bandwidth Operation

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 see the effect of the UK RTTT
channel restrictions in the 15 MHz bandwidth (Figure 11), where blocks in red indicate
channels that are barred. Barred channels are indicated by a "No Entry" symbol displayed on
the "Spectrum Management" web page, see Section 7.9.11 "Spectrum Management Control
with Radar Avoidance".

NOTE
Radar avoidance requirements in the 5.4 GHz band in the EU is detailed in
specification EN 301-893 version V1.4.1 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.
