Abstract
A wireless device (110) is provided for supporting peer to peer communications. A transceiver (132) is configured to receive and transmit data over a wireless link. A network activity sensor (136) is coupled to the transceiver and configured to sense peer to peer activity by the transceiver and generate a network activity sensor signal. A controller (140) is coupled to the network activity sensor (136) and the transceiver (132), and configured to selectively deactivate a portion of the wireless device based at least in part on the network activity sensor signal. Advantages of the invention include the ability to prolong battery life in wireless devices.
