Abstract
A receiver of a mobile device is deactivated and reactivated between frames of a data transmission system. In one example, a radio receiver of a mobile device is activated. The radio receiver listens for preambles of frames transmitted by radio transmitters and receives a frame preamble. The receiver is deactivated upon receiving a frame preamble. The receiver is then reactivated after a time determined based on the received frame preamble to receive a subsequent frame preamble. The receiver receives the subsequent frame preamble, determines an address for the subsequent frame, and receives the subsequent frame, if the address corresponds to the mobile device.
