Dynamic Power Save Techniques for Next Generation WLAN Systems

The next generation 802.11 systems (802.11n) are geared towards high performance. Higher performance usually means higher dynamic power consumption. In this paper we describe techniques to reduce the dynamic power consumption in WLAN systems to help increase the battery life in mobile systems. Techniques that can be employed at the baseband based on the protocol knowledge, based on the dataflow implementation and microarchitecture techniques are explored. Techniques for the analog/RF portion of the WLAN system are also explored
