Abstract

To avoid interference with radar systems in the 5GHz, wireless devices detect radar and vacate any channels currently used by the radar system. In a channel switching technique, if the new channel is radar-exempt, then normal operation commences on the new channel. If the new channel is non-radar-exempt, then normal operation commences on a temporary radar-exempt channel and an aggregate background scan can be performed on the new channel. If no radars are detected using the aggregate background scan, then operation is switched from the temporary channel to the new channel.
