Method and apparatus for directed adaptive control of dynamic channel selection in wireless networks
First Claim
1. A system, comprising:
- a radio detector configured to scan for radar in each of a plurality of 5 GHz communication channels associated with an access point, wherein the radio detector comprises a first radio configured to monitor for intermittent radar for a first range of dynamic frequency selection (DFS) frequencies, and wherein the radio detector comprises a second radio configured to monitor for intermittent radar for a second range of DFS frequencies; and
a DFS master device configured to perform a channel availability check (CAC) associated with the plurality of 5 GHz communication channels.

Abstract
The present invention relates to wireless networks and more specifically to systems and methods for selecting available channels free of radar signals from a plurality of radio frequency channels. In one embodiment, the present invention provides a standalone multi-channel DFS master device and a cloud intelligence device. The standalone multi-channel DFS master device generates spectral information associated with a plurality of communication channels for a device in communication with the standalone multi-channel DFS master device. The cloud intelligence device receives the spectral information via a network device, integrates the spectral information with other spectral information to generate integrated spectral information, and determines a communication channel for the device that is selected from the plurality of communication channels based at least on the integrated spectral information.
