2.4.4 Channel Reuse Parameters
Channel Reuse parameters are applicable only for AU/BU using a Country Code
that supports 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 section includes the following options:
2.4.5 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
and 1064), enabling to select the DFS detection algorithm if DFS should be
enabled.
The available options are ETSI and FCC.
2.4.6 Remote Radar Reports to Leave
This section is applicable only for AUs and BUs. If an AU/BU receives from the
SUs a particular number of DFS notifications (Remote Radar Reports) in a
specified period of time (Remote Radar Monitoring Period), it will initiate a channel
shutdown on that frequency, and tag it as Radar Detected. The Remote Radar
Reports to Leave section includes the following options:
Channel Reuse Option This parameter allows enabling/disabling the channel reuse
algorithm.
Assessment Period
(Hours)
The period in hours used for assessment of radar activity in the
original channel.
The range is 1 to 12 hours.
Max Detections In
Assessment Period
The maximum number of radar detections in the original channel
during the Assessment Period that is required for reaching a decision
to try again the original channel.
The range is 1 to 10 radar detections.
