4.2.6.2.4.4 Channel Reuse Parameters (DFS+)
The Channel Reuse algorithm enables returning to the original channel under
certain conditions that indicate low radar activity on the original channel. The
conditions are that radar was detected in this channel not more than N times
(Maximum Number of Detections in Assessment Period) during the last T hours
(Radar Activity Assessment Period). When the Channel Reuse Option is enabled,
then by the end of the Channel Avoidance Period the unit will attempt returning
to the original frequency, provide these conditions are met.
The Channel Reuse Parameters submenu includes the following options:
Channel Reuse Option: Enabling/disabling the Channel Reuse algorithm.
