Abstract

A wireless device (110) is provided for supporting extended battery life. A transceiver (132) is configured to receive and transmit data over a wireless link. A frame detection sensor (140) is coupled to the transceiver and configured to sense an incoming frame and generate an incoming frame sensor signal. A controller (142) is coupled to the frame detection sensor and transceiver, and configured to selectively deactivate a portion of the transceiver device based at least in part on the frame sensor signal. Advantages of the invention include the ability to extend battery life in mobile wireless devices.

Description

technical field [0001] The present invention relates to the general field of wireless local area networks (WLANs), and more particularly to improving the lifespan of batteries in mobile devices. Background technique [0002] Currently, wireless local area networks (WLANs) are evolving, and communication speeds are increasing day by day. However, mobile wireless devices use a significant portion of the power to operate the transceiver portion of the device. Therefore, when the mobile device is actively using WLAN communications, the battery life will be reduced. [0003] Currently, one of the most popular wireless protocols is 802.11, which represents an IEEE standard. The 802.11 protocol has various types, such as 802.11a, 802.11b, and so on. The IEEE 802.11b WLAN standard provides a protocol standard that includes receivers configured to detect WLAN frames. The receiver continuously performs a detection algorithm on any received signal in order to find the synchronous p...
