An Energy Efficiency Figure of Merit for Radio Transceivers

Selection of an energy efficient wireless transceiver is an important step in the design of any low power wireless system, specifically wireless sensor networks or IoT devices. In this paper, a figure of merit (FoM) for evaluating the energy efficiency of wireless radio transceivers is proposed. Using this FoM, it is possible to easily compare the performance of transceivers built with completely different technologies, in term of energy efficiency. This FoM can be used as a practical tool for researchers and engineers to evaluate wireless transceivers and determine the state-of-the-art or select a desired transceiver.
