Abstract
Methods and apparatus for an electronic device to perform a dynamic frequency selection (DFS) proxy function are described. An interface circuit of the electronic device receives, from an access point associated with the electronic device, a frame with DFS information that indicates a presence of interference associated with a higher priority user in a shared band of radio frequencies. The frame can include an action frame with a channel switch announcement (CSA) or a beacon with a CSA. In response to receiving the DFS information, the electronic device forwards, to a third electronic device, the DFS information, where the third electronic device is not associated with and does not have a connection to the access point. In this way, the electronic device functions as a DFS proxy for the third electronic device with respect to the shared band of radio frequencies used by the access point.
