DEVICE, SYSTEM AND METHOD OF POWER MANAGEMENT IN A WIRELESS AREA NETWORK

摘要

A first wireless communication device includes a wireless communication unit to transmit to a control point of a wireless network an information request frame identifying a second wireless communication device in the wireless network; wherein the wireless communication unit is to receive from the control point a response including wakeup information indicating a wakeup schedule of the second wireless communication device; and wherein, based on the wakeup information, the wireless communication unit is to transmit a wireless transmission to the second wireless communication device during a wakeup period indicated in the wakeup schedule. The wireless communication unit transmits a wireless transmission directly to the latter device during the wakeup period based on the wakeup information. The device facilitates power consumption by switching a station from an active mode of operation to a power save mode of operation, thus prolonging service life of a battery.
