ES 202 706-2 Metrics and measurement method for energy efficiency of wireless access network equipment; Part 2: energy efficiency

This standard starts with the assumption that the energy consumption of the access network dominates the energy consumption of other subsystems of the wireless telecom networks. It also defines the measurement method for evaluating base station power and energy consumption. ETSI ES 202 706-2 focuses on scenarios with dynamic loads and all radio technologies but 5G. ETSI TS 103 786 fills in the missing part, namely 5G, under dynamic load. Various (dynamic) data traffic models are used to describe the loads. Under a specific data traffic model, a set of UEs download files of various sizes while roaming around a base station at three locations (near, middle, and far range). Three levels of load, low, medium and busy hour (named just as in the static case), are determined by an appropriate combination of parameters in the traffic model (e.g. waiting time between two consecutive downloads, total number of UEs, etc.).
