Abstract
An access point includes a beacon module and a control module. The access point transmits a beacon during a beacon interval. The beacon module determines a first portion of the beacon interval and a second portion of the beacon interval. The access point operates in a normal mode during the first portion of the beacon interval. The control module operates the access point in a power save mode during the second portion of the beacon interval. The control module operates the access point in the power save mode in response to a client station not communicating with the access point during the first portion of the beacon interval.
