This ETSI Standard (ES) has been produced by ETSI Technical Committee Environmental Engineering (EE).

The present document was developed jointly by ETSI TC EE and ITU-T Study Group 5. It will be published

respectively by ITU and ETSI as Recommendation ITU-T L.1330 [i.4] and ETSI ES 203 228 (the present document),

Moreover the present document has been developed in collaboration with 3GPP SA5 and RAN3; GSMA has also given

In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and

"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of

"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.

The present document deals with the definition of metrics and methods to measure energy efficiency performance of

Mobile Radio Access Networks and adopts an approach based on the measurement of such performance on small

networks, for feasibility and simplicity purposes. Such simplified approach is proposed for approximate energy

efficiency evaluations and cannot be considered as a reference for planning evaluation purposes throughout the network

operation process. The same approach was introduced also in ETSI TR 103 117 [i.1]; the measurements in testing

laboratories of the efficiency of the Base Stations is the topic treated in ETSI ES 202 706 [i.2].

The measurement of this performance is useful for many reasons, and an implementation guidelines clause is given

The present document provides also an extrapolation method to extend the applicability of the assessment of energy

The general outcome of the application of the method specified in the present document is based on the "Assessment

report" introduced in clause 8. An example of application of the method is given for better readability and ease of use in

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

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,
