This Recommendation aims to define the topology and level of analysis necessary to assess the energy efficiency (EE) of mobile networks. Within the scope of this Recommendation are the radio access parts of the mobile network, namely: radio base stations, backhauling systems, radio controllers and other infrastructure radio site equipment. The technologies covered are: global system for mobile communications (GSM), universal mobile telecommunications communications (UMTS) and longterm evolution (LTE) (including LTE advanced (LTE-A)). In particular, this Recommendation defines metrics for mobile network energy efficiency and methods for assessing (and measuring) energy efficiency in operational networks. The purpose of this specification is to allow better comprehension of network energy efficiency.

This Recommendation deals with both homogeneous and heterogeneous "networks" and considers networks 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 consists of a control node (whenever applicable), its supported access nodes, as well as its related network elements. Networks could also be defined by geographic boundaries, such as citywide, national or continental networks or by demographic boundaries, such as urban or rural networks.

This specification applies to the so-called "partial" networks where energy efficiency is measured in a standardized way. This specification extends the measurements in partial networks to wider so-called "total" network energy efficiency estimations (e.g., the network in a geographic area, the network in an entire country, the network of a mobile network operator (MNO)).

Terminal (end-user) equipment is outside the scope of this Recommendation and thus, is not considered in the energy efficiency measurement.
