Worldwide, most of the 5-GHz band frequencies are used by radar systems. The same frequency bands (or subsets) were allocated to unlicensed WLAN devices. A requirement arising from this frequency band reuse is a method called dynamic frequency selection (DFS). A system that requires DFS must be capable of avoiding interference with radar systems, according to the regulatory requirements as described in each DFS standard.
WiLink8.0 possesses DFS master capabilities in all three regulatory domains: TELEC, FCC, and ETSI. The active domain is configured according to the Region parameter. WiLink8 AP can work on DFS channels according to these regulatory domains. AP has the capability to perform channel availability check prior to operating on a DFS channel. AP has the capability to detect radars during operation on a DFS channel. Upon radar detection the AP will move to a randomly selected channel. STA(s) that were connected to the AP on a DFS channel will receive a CSA in the AP beacons.
