I really wish there is a similar tool for measuring energy consumption of a transceiver power amplifier (PA) inside any wireless device because the efficiency is abysmal (less than 50% in real life scenario due to impedance matching, skin effect, etc) not unlike the internal combustion engine (ICE) but at least the latter do not need to deal with mismatched and high frequency issues. In fact PA is increasingly becoming the main culprit of energy wasting in any connected devices especially the wireless ones, and about 50% of the power consumption of the entire device system by the PA are normal. With IoT and machine-to-machine (M2M) type of communications where data transmissions are regular and frequent unlike human type of communication where they sleep at night, machines mostly never sleep and this makes the PA inefficiency becomes even more notorious compared to human communications.
