  • Patent number: 9942800
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for load balancing network traffic in a wireless network. In one aspect, an access point may determine a plurality of client devices that are associated with an overloaded channel of the wireless network. The access point may identify a first client device of the plurality of client devices based, at least in part, on an airtime consumed on the overloaded channel. The access point may determine one or more alternate paths between the access point and the first client device. The access point may forecast airtime to be used by the first client device on channels of the one or more alternate paths, and steer wireless network traffic of the first client device to a first alternate path of the one or more alternate paths based, at least in part, on the forecasted airtime.
