PPT-Enfold: Downclocking OFDM in

WiFi Feng Lu Patrick Ling Geoffrey M Voelker and Alex C Snoeren UC San Diego Researchers report active WiFi radio can consume up to 70 of a smartphones energy Rozner . Voelker and Alex C Snoeren University of California San Diego Abstract Dynamic voltage and frequency scaling DVFS has long been used as a technique to save power in a variety of computing domains but typically not in communications devices A fundame There are different “flavors” of OFDM according what we put in the Prefix:. data.
