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. In one embodiment, the present invention includes a Wi-Fi coordinator device that receives client device information from client devices connected to an access point in a network. The Wi-Fi coordinator sends the client device information to a cloud intelligence engine which then combines the client device information with other client device information to identify the client devices in the network and their Wi-Fi capabilities and limitations. Using this information, the cloud intelligence devices determines the access point settings that would optimize the operation of the network.
