SummaryRecommendation 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. |
