4.7.2.2.2.1.2.3 Channel Non Occupancy Period (min)
If radar was detected on a certain frequency, this frequency will be considered as
Unavailable for a period defined by the Channel Non Occupancy Period
parameter. During this period this frequency will not be used by the DFS
mechanism.
The range is from 0 to 60 minutes.
The default is 30 minutes.
4.7.2.2.2.1.2.4 Startup Test Valid Period (hours)
After deciding that a frequency is Available (no radar was detected by the Channel
Availability Check algorithm), it is considered as an Available frequency for a
period defined by the Startup Test Valid Period parameter. During this period the
unit may start transmitting on this frequency without performing a Channel
Availability Check.
The range is from 0 to 48 hours.
The default is 6 hours.
4.7.2.2.2.1.2.5 Radar Detection Threshold (dBm)
The Radar Detection Threshold is the minimum level of received radar signal that
must be detected by the algorithm assuming an Rx Antenna gain of 0 dBi. The
higher the EIRP, the higher should be the Radar Detection Threshold.
The range is from -70 to -36 dBm.
The default depends on the EIRP (Tx Power + Antenna Gain) of the Sector:
