Foreword
This final draft ETSI Standard (ES) has been produced by ETSI Technical Committee Environmental Engineering (EE),
and is now submitted for the ETSI standards Membership Approval Procedure.
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),
which are technically-equivalent.
Moreover the present document has been developed in collaboration with 3GPP SA5 and RAN3; GSMA has also given
valuable suggestions and contributions.
Modal verbs terminology
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
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Introduction
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
(clause 9) to help using the present document in the most convenient way.
The present document provides also an extrapolation method to extend the applicability of the assessment of energy
efficiency to wider networks (clause 7).
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
annex A.

1 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.

4.1 Introduction
The Mobile Radio Access Network (MN) under investigation shall include all the equipment that is necessary to run a
radio access network or sub-network. Equipment to be included in the Mobile Network under investigation:
• Base Stations (see ETSI TS 125 104 [1] and ETSI TS 136 104 [2]):
- Wide area BS.
- Medium range BS.
- Local Area BS.
- Home BS.
NOTE: Home BS (and Wi-Fi access points) are not dealt with in the present document, being possibly considered
for future versions.
• Site equipment (air conditioners, rectifiers/ batteries, fixed network equipment, etc.).
• Backhaul equipment required to interconnect the BS used in the assessment with the core network.
• Radio Controller (RC).
Power consumption and energy efficiency measurements of individual mobile network elements are described in
several standards (for example ETSI ES 202 706 [i.2] for radio base stations). The present document describes energy
consumption and MN energy efficiency measurements in operational networks.
As a complete and detailed energy consumption measurement of the complete network of a country or MNO is in most
cases impossible or economically not viable, the total network is split into a small number of networks with limited size
("sub-networks").
These sub-networks are defined to represent some specific characteristics, for example:
• capacity limited networks representing urban and dense urban networks;
• sub-urban networks with high requirements for coverage and capacity;
• rural networks, which are usually coverage limited.

Foreword
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),
which are technically-equivalent.
Moreover the present document has been developed in collaboration with 3GPP SA5 and RAN3; GSMA has also given
valuable suggestions and contributions.
Modal verbs terminology
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
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Introduction
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
(clause 9) to help using the present document in the most convenient way.
The present document provides also an extrapolation method to extend the applicability of the assessment of energy
efficiency to wider networks (clause 7).
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
annex A.

1 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.
