  • Publication number: 20170142728
    Abstract: Multiple detector coordination for monitoring of multiple channels in the dynamic frequency selection band is provided herein. A method includes performing a channel availability check on a first 5 GHz radio channel selected from a plurality of 5 GHz radio channels. The method can also include communicating to an access point device servicing a client that the first 5 GHz radio channel is available for use based on a first determination that the first 5 GHz radio channel does not comprise the first radar signal. The method can also include performing a soft handover of dynamic frequency selection functionalities to the access point device. The DFS functionalities comprise continuous in-service monitoring of the first 5 GHz radio channel. The radar detector, the beacon generator, and the 5 GHz radio transceiver discontinue continuous in-service monitoring of the first 5 GHz radio channel after the soft handover.
