Summary

Recommendation ITU-T L.1350 contains basic definitions of energy efficiency metrics, to evaluate the energy efficiency of a base station site including 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, generator and cable losses.

The following energy factors will be considered for the evaluation:

•            electric energy from a public grid;

•            electric energy generated by generators such as diesel generators for emergency or normal operation purposes;

•            renewable energy.

Measurement methodologies for the parameters considered in the metrics proposed are contained in other ITU-T Recommendations of the same series.
