Abstract
A novel and useful apparatus for and method of Improving idle connection state power consumption in wireless local area network (WLAN) system. Beacon transmission delay information is determined by the access points and advertised to the stations via a Beacon Transmission Delay Information Element. In response, the stations adjust their Wake For Beacon Reception time accordingly to wake up at a time much closer to the actual receipt of the Beacon, thereby reducing power consumption due to the reduced time the receive circuits need to be powered on.
