Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Environmental Engineering (EE). Introduction Energ
19、y efficiency is one of the critical factor of the modern telecommunication systems. The energy consumption of the access network is the dominating part of the wireless telecom network energy consumption. Hence the core network and the service network are not considered in the present document. In th
20、e access network, the power consumption of the Radio Base Station node sites (later referred as RBS sites) is dominating and the power consumption of Radio Network Control nodes (RNC or BSC) are not considered in the present document. The present document defines harmonized methods to evaluate the e
21、nergy efficiency of wireless access networks. In order to do that, the present document provides definitions for the following indicators: Average power consumption of RBS equipment in clause 5.1: The RBS average power consumption is based on measured RBS power consumption under reference configurat
22、ion, reference environment and under reference load levels. Average power consumption of RBS site in clause 5.2: The RBS site level power consumption is calculated based on RBS equipment power consumption for reference RBS site configuration using correction factors for different power supply, cooli
23、ng and site solutions. Performance indicators for network level energy efficiency for wireless systems in clause 5.3: The network level performance indicators are calculated based on RBS site level reference power consumption as well as based on RBS coverage area for rural area and RBS capacity for
24、urban area. ETSI ETSI TS 102 706 V1.3.1 (2013-07)61 Scope The present document defines a method to analyse the energy efficiency of wireless access network equipment. The present document version covers the following radio access technologies: GSM. LTE. WCDMA. WiMAXTM. As the RBS power consumption i
25、s the dominant part of total power consumption of wireless access network, the present document covers methods which take into account only the RBS site power consumption when defining the total power consumption of wireless access networks. In the dynamic measurement, functionalities located in RNC
26、 or BSC node, which may have a significant impact on power consumption of base station nodes, are also considered. The methodology described in the present document to measure energy efficiency consists of two parts. Within the present document they are referred to as static and dynamic measurements
27、. The results based on “static“ measurements of the RBS power consumption provide a power consumption figure for RBS under static load and without radio network features activated. The results based on “dynamic“ measurements of the RBS power consumption provide a power consumption figure for RBS wit
28、h dynamic load and with radio network features activated, i.e. including the functionalities located in the radio network controller e.g. BSC/RNC. 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 targ
29、et values for the energy efficiency of equipment or networks. The results should only be used to assess and compare the efficiency of mobile radio network equipment from different vendors featuring the same mobile radio standard and frequency band. The present document does not cover multi RAT. Only
30、 Wide Area Base Stations are covered in this version. Other type of RBS will be considered in a future version of the present document. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
