Enables or disables the "Dynamic Frequency Selection (DFS)" function.
– Enabled
if you have enabled this function, additional DFS channels from the 5 GHz band are
available to you. These channels are country-specific and are subject to certain DFS
regulations.
If the access point discovers a disturbance on the current channel, it changes
automatically to an alternative channel and the current channel is blocked for 30
minutes. The disturbance can originate from a primary user or radar interference.
Before the access point starts the communication on a channel it searches 60
seconds for primary users on the channel. During this time the access point does not
send beacons. If signals are found on the channel, the access point changes channel
and repeats the check. Only when no signals from primary users are detected after 60
seconds does the access point send on a channel.
The access point also searches for primary users during operation.
– Disabled
The DFS function is not used.
Note
RCoax 5 GHz and DFS
In the USA and in countries that follow the FCC (Federal Communication Commission)
when operating with DFS (Dynamic Frequency Selection), the IWLAN RCoax Cab
le 5
