5G power use per bit is supposedly going to be far lower than 3G/4G.
For shorter ranges because higher frequency.
For average per-bit cost, because more bits/sec in the higher frequency encoding.
But, for IoT there is the burden of turning the RF segment on, finding lock, sending. So, for small 'grams' of message it won't necessarily be as good as the per-bit cost for streaming data or long lived associations. And, shorter ranges: You will be deploying more base stations. Albiet with lower power budget too, but .. Nothing is free.
