4. Achieving higher Energy Efficiency and Greener Green ICT
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.
