A first look at 802.11n power consumption in smartphones

We report the first measurement study of 802.11n power consumption in smartphones. Using a popular 802.11n-enabled smartphone and an 802.11n wireless testbed, we evaluate the power and energy consumption on the phone for a variety of configurations including different MAC bitrates, frame sizes, and channel conditions. We contrast our results against recent studies using 802.11n wireless cards for desktop/laptop computers. Our findings have significant implications in the design of energy efficient rate adaptation algorithms for the next generation of 802.11n-enabled smartphones.
