is upgraded from a SW version lower than 5.2, the feature will not be
automatically applicable. If the user wants to use the DFS feature, he must
re-apply the Country Code values (see section “Re-apply Country Code Values” on
page 179). Note also that for these units, if the user changes the working
sub-band the DFS Option will be automatically set to No. For other Country
Codes that support DFS when sub-band is changed the DFS Option is forced to
Yes.
The DFS Parameters submenu includes the following parameters:
4.2.6.2.5.3.1 DFS Required by Regulations
The DFS Required by Regulations option enables defining whether DFS should be
used for compliance with applicable local regulations. The options are Yes or No.
Selection of the No option will disable the radar detection and dynamic frequency
selection mechanism.
The default depends on the Country Code (No for Universal Country Codes in the
5.4 and 5.8 GHz bands, Yes for all other Country Codes that support DFS as
required by applicable regulations).
4.2.6.2.5.3.2 Channel Check Time
The Channel Check Time defines the time allocated for checking whether there is
a radar activity on a new frequency after power up or after attempting to move to a
new frequency upon detecting radar activity on the previously used frequency.
During this time the unit does not transmit.
The range is 1 to 3600 seconds.
The default is 60 seconds.
4.2.6.2.5.3.3 Channel Avoidance Period
The Channel Avoidance Period defines the time that the frequency will remain
marked in the database as Radar Detected or Adjacent to Radar after detecting
radar activity. These frequencies will not be used when searching for a new
frequency. When this time has elapsed, the unit frequency's marking will change
to Radar Free.
The range is 1 to 60 minutes.
The default is 30 minutes.
NOTE
When ETSI country codes are applied, on operating channels overlappling partially or totally with
frequency range 5600 - 5650 MHz, the Channel Check Time is forced to minimum 600 seconds (10
minutes).
