4.2.6.2.5.3.4 Minimum Pulses to Detect
The Minimum Pulses to Detect parameter defines the minimum number of radar
pulses that should be detected before reaching a decision that radar is active on
the channel.
The range is from 1 to 100 pulses.
The default is 4 pulses.
4.2.6.2.5.3.5 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, provided these conditions are met.
The Channel Reuse Parameters submenu includes the following options:
Channel Reuse Option: Enabling/disabling the Channel Reuse algorithm.

The default is Disable.
Radar Activity Assessment Period: The period in hours used for assessment

of radar activity in the original channel.
The range is 1 to 12 hours.
The default is 5 hours.
Maximum Number of Detections in Assessment Period: The maximum

number of radar detections in the original channel during the Radar Activity
Assessment Period that is required for reaching a decision to try again the
original channel.
The range is 1 to 10 radar detections.
The default is 5 radar detections.
4.2.6.2.5.3.6 DFS Detection Algorithm
The DFS Detection Algorithm option is applicable only to units using a Universal
Country Code in either the 5.4 GHz or the 5.8 GHz band (Country Codes 1060
