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.
