scope:

This Recommendation specifies principles and concepts of energy efficiency metrics used to evaluate the energy efficiency of a base station site considering the energy consumption for:

• the telecom equipment inside the base station site e.g., backhaul and base station equipment;

• the entire infrastructure, including cooling systems, monitoring systems (for power consumption, equipment running status, environment parameters, etc.), fire protection and lighting systems for all the sites;

• energy losses due to AC/DC rectifiers, generators and cable losses.

This Recommendation shall not be used to evaluate the energy efficiency of equipment that are covered by other Recommendations such as [ITU-T L.1310] and [ITU-T L.1320].
