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.

Abstract: The present invention relates to wireless networks and more specifically to systems and methods for selecting and implementing communication parameters used in a wireless network to optimize communication between access points and client devices while accounting for effects of adjacent networks. In one embodiment, the present invention includes a Wi-Fi coordinator device that receives packet information from devices within wireless range of the Wi-Fi coordinator. The Wi-Fi coordinator sends the packet information to a cloud intelligence engine which then time shifts the packet information and combines the packet information with other packet information. Using this integrated packet information, the cloud intelligence devices determines the access point settings to improve the operation of the network.
