ABSTRACT:
A low power packet detector (LPPD) can significantly reduce the average power consumption of WLAN devices. The LPPD takes advantages of 802.11 protocols to turn on and off selected modules of an 802.11 receiver based on the packets on the medium and the decoding stages. The LPPD can be implemented mostly in firmware with minor hardware modifications to existing chips or be implemented in ASIC technology that takes full advantages of the power saving made possible by it.
