Coding and Diversity Gains of Low Power Radio Communications: BLE and ZigBee

Abstract

This paper is dedicated to compare energy efficiencies of ZigBee and Bluetooth radios studying their coding performances. The issue has been a hidden underneath bit energy and power consumptions of the devices. First, recent advances have changed energy consumption of the devices and secondly, in terms of power efficiency, the coding gain of the systems have been suppressed by Signal to Noise Ratio (SNR) definition where the bit energy to noise ratio (Eb/No) value of the reception is more meaningful providing direct comparative value for the systems. In the end, the paper has concluded that the diversity gains of the systems are more effective, whatever the technique can provide a diversity gain over statistical average.
