Power Consumption Characteristic of low power Wireless Transceivers

Abstract

Wireless transceivers are typically the most power-hungry component in wireless sensor nodes. A closer investigation into the power consumption behavior of these components can lead to the optimization of wireless sensor networks or IoT systems. In this paper, we present an analytical method based on the energy efficiency Figure of Merit (FoM) to estimate the power consumption characteristics of a typical MOSFET-based wireless transceiver. We show that the best energy efficiency can be achieved in a radio transceiver when the energy consumed in the receiving mode is approximately equal to the energy consumed during transmission.
