Energy-efficiency vs. performance optimization in low-power wireless transmission

In this paper we analyze energy-efficiency vs. performance trade-off in low power wireless communications at component level and check hypothesis that the trade-off can be improved by introducing power supply voltage as design variable compared to the case when power supply voltage is fixed. We set two testing formulations and analysis based on SI4455 transceiver show that the hypothesis holds true for both. Moreover, we show that almost 130% less power can be consumed when optimal setting is used in SI4455 transceiver, compared to the case when very low output power is produced under the high power supply voltage.
