Environmental Engineering (EE) - Metrics and measurement method for energy efficiency of wireless access network equipment - Part 1: Power consumption - static measurement method

The present document version covers base stations with the following radio access technologies:
• GSM.
• WCDMA.
• LTE.
• NR.
The methodology described in the present document is to measure base station static power consumption and RF output
power. Within the present document it is referred to as static measurements.
The results based on "static" measurements provide power and energy consumption figures for BS under static load.
Energy consumption of terminal (end-user) equipment is outside the scope of the present document.
The scope of the present document is not to define target values for the BS power and energy consumption.
The results should only be used to assess and compare the power and energy consumption of complete base stations.

Foreword

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

The present document is part 1 of a multi-part deliverable covering the metrics and measurement method for energy

efficiency of wireless access network equipment, as identified below:
ETSI ES 202 706-1: "Power consumption - static measurement method";
ETSI TS 102 706-2: "Energy Efficiency - dynamic measurement method".
Modal verbs terminology

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

Introduction

Energy efficiency is one of the critical factors of the modern telecommunication systems. The energy consumption of

the access network is the dominating part of the wireless telecom network energy consumption. Therefore the core

network and the service network are not considered in the present document. In the radio access network, the energy

consumption of the Base Station is dominating (depending on technology often also referred to as BTS, NodeB,

eNodeB, gNodeB etc. and in the present document denoted as BS).

The present document, ETSI ES 202 706-1, defines the measurement method for the evaluation of base station power

consumption and energy consumption with static load:

• Average power consumption of BS equipment under static test conditions: the BS average power consumption

is based on measured BS power consumption data under static condition when the BS is loaded artificially in a

lab for three different loads, low, medium and busy hour under given reference configuration.

• Daily average energy consumption.

1 Scope

The present document version covers base stations with the following radio access technologies:

• GSM.
• WCDMA.
• LTE.
• NR.

The methodology described in the present document is to measure base station static power consumption and RF output

power. Within the present document it is referred to as static measurements.

The results based on "static" measurements provide power and energy consumption figures for BS under static load.

Energy consumption of terminal (end-user) equipment is outside the scope of the present document.

The scope of the present document is not to define target values for the BS power and energy consumption.

The results should only be used to assess and compare the power and energy consumption of complete base stations.

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 is part 1 of a multi-part deliverable covering the metrics and measurement method for energy

efficiency of wireless access network equipment, as identified below:
ETSI ES 202 706-1: "Power consumption - static measurement method";
ETSI TS 102 706-2: "Energy Efficiency - dynamic measurement method".
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

Energy efficiency is one of the critical factors of the modern telecommunication systems. The energy consumption of

the access network is the dominating part of the wireless telecom network energy consumption. Therefore the core

network and the service network are not considered in the present document. In the radio access network, the energy

consumption of the Base Station is dominating (depending on technology often also referred to as BTS, NodeB,

eNodeB, gNodeB etc. and in the present document denoted as BS).

The present document, ETSI ES 202 706-1, defines the measurement method for the evaluation of base station power

consumption and energy consumption with static load:

• Average power consumption of BS equipment under static test conditions: the BS average power consumption

is based on measured BS power consumption data under static condition when the BS is loaded artificially in a

lab for three different loads, low, medium and busy hour under given reference configuration.

ETSI
---------------------- Page: 5 ----------------------
6 Final draft ETSI ES 202 706-1 V1.6.0 (2020-11)
• Daily average energy consumption.

ETSI TS 102 706-2 [i.8] defines energy efficiency measurement of the base station with dynamic load.

1 Scope

The present document version covers base stations with the following radio access technologies:

• GSM.
• WCDMA.
• LTE.
• NR.

The methodology described in the present document is to measure base station static power consumption and RF output

power. Within the present document it is referred to as static measurements.

The results based on "static" measurements provide power and energy consumption figures for BS under static load.

Energy consumption of terminal (end-user) equipment is outside the scope of the present document.

The scope of the present document is not to define target values for the BS power and energy consumption.

The results should only be used to assess and compare the power and energy consumption of complete base stations.

Wide Area Base Stations and Medium Range Base Stations (as defined in ETSI TS 125 104 [2], ETSI TS 136 104 [12],

and ETSI TS 138 104 [15]) are covered in the present document.

ETSI TS 102 706-2: "Energy Efficiency - dynamic measurement method".

Introduction

Energy efficiency is one of the critical factors of the modern telecommunication systems. The energy consumption of

the access network is the dominating part of the wireless telecom network energy consumption. Therefore the core

network and the service network are not considered in the present document. In the radio access network, the energy

consumption of the Base Station is dominating (depending on technology often also referred to as BTS, NodeB,

eNodeB, gNodeB etc. and in the present document denoted as BS).

The present document, ETSI ES 202 706-1, defines the measurement method for the evaluation of base station power

consumption and energy consumption with static load:

• Average power consumption of BS equipment under static test conditions: the BS average power consumption

is based on measured BS power consumption data under static condition when the BS is loaded artificially in a

lab for three different loads, low, medium and busy hour under given reference configuration.

• Daily average energy consumption.

1 Scope

The present document version covers base stations with the following radio access technologies:

• GSM.
• WCDMA.
• LTE.
• NR.

The methodology described in the present document is to measure base station static power consumption and RF output

power. Within the present document it is referred to as static measurements.

The results based on "static" measurements provide power and energy consumption figures for BS under static load.

Energy consumption of terminal (end-user) equipment is outside the scope of the present document.

The scope of the present document is not to define target values for the BS power and energy consumption.

The results should only be used to assess and compare the power and energy consumption of complete base stations.

Wide Area Base Stations and Medium Range Base Stations (as defined in ETSI TS 125 104 [2], ETSI TS 136 104 [12],

and ETSI TS 138 104 [15]) are covered in the present document.
