ITU‐T L.1350 Energy efficiency metrics of a base station site

ITU‐T L.1331 Assessment of mobile network energy efficiency 

Mobile network data energy efficiency (EEMN,DV) is the ratio between the performance indicator (DVMN) and the energy consumption (ECMN) when assessed during the same time period. 

EEMN,DV = /

SEE=(ECT/ETS)×100% the ration between total energy consumption of telecommunication equipment and total energy consumption on site.
