In this paper, we analyze energy-efficient communications based on an advanced energy consumption model for wireless devices. The developed model captures relationships between transmission power, transceiver distance, modulation order, channel fading, power amplifier (PA) effects, as well as other circuit components in the radio frequency transceiver. Based the developed model, we are able to identify the optimal modulation order in terms of energy-efficiency under different situations (e.g., different transceiver distance, different PA classes and efficiencies, different pulse shape, etc). This provides an important framework for analyzing energy-efficient communications for different wireless systems ranging from cellular networks to wireless Internet of Things.
