The radar detection algorithm will always scan the active channel for 60 seconds for radar
interference before using the channel. This compulsory channel scan will mean that there is a
60 seconds service outage every time radar is detected and that the installation time is
extended by 60 seconds even if there is found to be no radar on the channel.
NOTE:
On system installation or start-up this extends the initial scan time of the Master unit
by 60 seconds.
To address the “provide aggregate uniform loading of the spectrum across all devices”
requirement, the channel selection algorithm will choose a channel at random from a list of
available channels. The channel selection algorithm is initiated at link initialization and when
radar interference is detected.
5.3.2
RTTT Avoidance and Other Channel Use Restrictions
Where regulatory restrictions apply to certain channels these channels are barred. The user
should note that the number of channels barred is dependant on the channel raster selected.
For example see the effect of the UK RTTT channel restrictions in Figure 13. Barred channels
are indicated by a “No Entry” symbol displayed on the “Spectrum Management” web page,
see section 8.3.9 “Spectrum Management Control - With Operational Restrictions”.
