Abstract

Self-directed movement of radio devices can enable large amounts of power gain since the sources of fluctuations in received signal power due to multipath-induced small-scale fading have highly localized effects. We call the gain achieved by finding a better location the mobility gain. University of Pennsylvania Experimental data for indoor as well as outdoor measurement studies are used to illustrate the potential of this RF-Mobility Gain concept over a wide range of frequencies. An analysis of the RF data reveals that a small amount of energy spent on searching for a better location can pay large dividends in long-term power expenditures for RF transmission. Challenges in building such a system for peer-to-peer links and network applications are discussed along with potential coordination algorithms.
