Okoljski inženiring (EE) - Ocenjevanje energijske učinkovitosti mobilnega omrežja
Cilj tega dokumenta je opredelitev topologije in ravni analize za ocenjevanje energijske učinkovitosti mobilnih omrežij. Na področje uporabe tega dokumenta spada del radijskega dostopa v povezavi z mobilnimi omrežji, tj. radijske bazne postaje, vmesni povezovalni sistemi, radijski krmilniki in druga infrastrukturna oprema radijskih mest. Zajete so tehnologije GSM, UMTS in LTE (vključno z LTE-A). Ta dokument določa zlasti metrike za energijsko učinkovitost mobilnih omrežij ter metode za ocenjevanje (in merjenje) energijske učinkovitosti v operativnih omrežjih. Namen tega dokumenta je zagotavljanje boljšega razumevanja energijske učinkovitosti omrežij.
Ta dokument obravnava tako homogeno kot heterogeno »omrežje« na podlagi omrežja, katerega velikost in obseg je mogoče določiti v okviru topoloških, geografskih ali demografskih omejitev. Za omrežja, določena v okviru topoloških omejitev, možen primer omrežja, ki ga zajema ta dokument, vključuje nadzorno vozlišče (če je na voljo), njegova podprta vozlišča za dostop in povezane elemente omrežja. Omrežja so lahko določena v okviru geografskih omejitev (npr. mestna, državna ali kontinentalna omrežja) in demografskih omejitev (npr. mestna ali podeželska omrežja).
Ta dokument obravnava tako imenovana »delna« omrežja, katerih energijska učinkovitost se meri na standardiziran način. Specifikacija razširi meritve v delnih omrežjih na ocene energijske učinkovitosti širših, tako imenovanih »celotnih« omrežij (tj. omrežje v geografskem območju, omrežje v celotni državi, omrežje operaterja mobilnega omrežja itd.).
Terminalska oprema (oprema končnih uporabnikov) ne spada na področje uporabe tega dokumenta in ni obravnavana v okviru meritve energijske učinkovitosti.

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.

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.
The size and scale of the sub-networks are defined by topologic, geographic or demographic boundaries. For networks
defined by topologic boundaries, a possible example of a network c

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.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
backhaul equipment: equipment used to connect base stations to the core network, or to other BSs (like X2 in LTE)
Base Station (BS): generic term used for network component which serves one cell or more cells and interfaces the
user terminal (through air interface) and a radio access network infrastructure
distributed RBS: BS architecture which contains radio heads (RRH) close to the antenna element and a central element
connecting BS to network infrastructure
Energy Efficiency (EE): relation between the useful output and energy/power consumption
energy saving feature: feature which contributes to decreasing the energy consumption compared to the case when the
feature is not implemented
integrated BS: BS architecture in which all BS elements are located close to each other for example in one or two
cabinets
NOTE: The integrated BS architecture may include TMA close to antenna.
Mobile Network (MN): set of equipment from the radio access network or sub-network that are relevant for the
assessment of energy efficiency
mobile network coverage energy efficiency: ratio between the area covered by the network in the Mobile Network
under investigation and the energy consumption
mobile network data energy efficiency: ratio between the performance indicator based on Data Volume and the
energy consumption when assessed during the same time frame
mobile network energy consumption: overall energy consumption of equipment included in the MN under
investigation
mobile network energy efficiency: Energy Efficiency of a Mobile Network
Mobile Network Operator (MNO): operator that manages one or more Mobile Networks
mobile network operator penetration ratio: percentage of traffic served by an MNO in the area where it is active
mobile network performance delivered: performance indicator of the MN under investigation, defined as the data
volume delivered by the mobile network under investigation during the time frame of the energy consumption
assessment
power consumption: power consumed by a device to achieve an intended application performance
radio access network: telecommunications network in which the access to the network (connection between user
terminal and network) is implemented without the use of wires and that is part of GERAN, UTRAN or E-UTRA
networks defined by 3GPP
Site Energy Efficiency (SEE): metric used to determine the energy efficiency of a telecom site
NOTE: SEE is defined by the ratio of "IT equipment energy" and "Total site energy", which generally includes
rectifiers, cooling, storage, security and IT equipment. For datacentres, the "Total site energy" more
globally includes building load, powering equipment (e.g. switchgear, uninterruptible power supply
(UPS), battery backup), cooling equipment (e.g. chillers, computer room air conditioning unit (CRAC))
and IT equipment energy.
telecommunication network: network operated under a license granted by a national telecommunications authority,
which provides telecommunications between Network Termination Points (NTPs)
Virtualized Network Function (VNF): See ETSI GS NFV 003 [i.3].
