Abstract
In a wireless network that uses some of the same channels as radars, an operationally separate radar detection device may be used to detect the presence of a radar signal, and notify at leas one network device of that detection so the wireless network devices may switch to a non-interfering channel. In some embodiments the detection device may be physically separate from other network devices, and may notify them via network communication messages. In other embodiments, the detection device may be physically and electrically attached to a network device, and may notify that device via an interrupt or other wired connection.
