Environmental Engineering (EE); Assessment of mobile network energy efficiency

Scope

The present document is aimed at defining the topology and level of analysis to assess the energy efficiency of mobile
networks. Within the scope of the present document there is the radio access part of the mobile networks, and namely
there are radio base stations, backhauling systems, radio controllers and other infrastructure radio site equipment. The
covered technologies are GSM, UMTS and LTE (including LTE-A). In particular the present document defines metrics
for mobile network energy efficiency and methods for assessing (and measuring) energy efficiency in operational
networks. The purpose of the present document is to allow better comprehension of networks energy efficiency.
The present document deals with both a homogeneous and heterogeneous "network" considering a network whose size
and scale could be defined by topologic, geographic or demographic boundaries. For networks defined by topologic
boundaries, a possible example of a network covered by the present document consists of a control node (whenever
applicable), its supported access nodes as well as the related network elements. Networks could be defined by
geographic boundaries, such as city-wide, national or continental networks and could be defined by demographic
boundaries, such as urban or rural networks.
The present document applies to the so-called "partial" networks where energy efficiency is measured in standardized
way. The specification extends the measurements in partial networks to wider so-called "total" networks energy
efficiency estimations (i.e. the network in a geographic area, the network in a whole country, the network of a MNO,
etc.).
Terminal (end-user) equipment is outside the scope of the present document and is not considered in the energy
efficiency measurement.
