Abstract
The present disclosure is directed to systems, apparatuses, and methods for operating a wireless local area network (WLAN) modem to perform WLAN channel change in a WLAN environment that is inhabited by radar devices, and therefore subject to a Dynamic Frequency Selection (DFS) requirement defined by the appropriate WLAN governing standards. Specifically, the present disclosure is directed to an apparatus and method for reducing or eliminating the amount of time in which a WLAN transceiver cannot transmit/receive data traffic while listening for radar signals on a channel allocated to radar devices for the minimum listening time specified by DFS.
