2.4.6 Air Interface DFS Tab (AU only)
The DFS tab enables defining the Dynamic Frequency Selection parameters. The
DFS tab is available only when managing an AU that uses a Country Code (Sub-
Band) with DFS supported.
Figure 2-17: DFS Tab
The DFS tab includes the following components:
 DFS Required by Regulations: This parameters define whether DFS is
required for compliance with applicable local regulations. When set to Yes, the
radar detection and dynamic frequency selection mechanism is activated.
 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 trying to move to a new frequency upon detecting radar activity on the
previously used frequency. During this time the AU does not transmit.
The range is 1 to 3600 seconds.
 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. Once this time has elapsed, the
unit frequency’s marking will change to Radar Free.
The range is from 1 to 60 minutes.
