Abstract: In an example embodiment, there is disclosed herein an apparatus comprising a wireless transceiver and a controller coupled to the wireless transceiver and configured to receive data via the wireless transceiver. The controller operates the wireless transceiver at a first power save state where the wireless transceiver can receive a frame but other circuits are de-energized. The controller is responsive to the wireless transceiver receiving a frame while the wireless transceiver is in a first power state to determine whether the frame is a predefined wakeup frame. The controller provides additional power to the wireless transceiver responsive to determining the frame is a predefined wakeup frame.

Abstract translation: 在示例性实施例中，这里公开了一种装置，其包括无线收发器和耦合到无线收发器的配置成经由无线收发器接收数据的控制器。 控制器在第一省电状态下操作无线收发器，其中无线收发器可以接收帧，但是其他电路被断电。 当无线收发器处于第一功率状态以确定帧是否是预定义的唤醒帧时，控制器响应于无线收发器接收帧。 响应于确定帧是预定义的唤醒帧，控制器向无线收发器提供额外的电力。
