1、 AMERICAN NATIONAL STANDARD FOR TELECOMMUNICATIONS ATIS-0600015.09.2015 Energy Efficiency for Telecommunication Equipment: Methodology for Measurement and Reporting of Base Station Metrics As a leading technology and solutions development organization, the Alliance for Telecommunications Industry So
2、lutions (ATIS) brings together the top global ICT companies to advance the industrys most pressing business priorities. ATIS nearly 200 member companies are currently working to address the All-IP transition, network functions virtualization, big data analytics, cloud services, device solutions, eme
3、rgency services, M2M, cyber security, network evolution, quality of service, billing support, operations, and much more. These priorities follow a fast-track development lifecycle from design and innovation through standards, specifications, requirements, business use cases, software toolkits, open
4、source solutions, and interoperability testing. ATIS is accredited by the American National Standards Institute (ANSI). The organization is the North American Organizational Partner for the 3rd Generation Partnership Project (3GPP), a founding Partner of the oneM2M global initiative, a member of and
5、 major U.S. contributor to the International Telecommunication Union (ITU), as well as a member of the Inter-American Telecommunication Commission (CITEL). For more information, visit www.atis.org. AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the
6、requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial a
7、greement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in an
8、y respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an i
9、nterpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute.

12、Purpose The purpose of this standard is to define a consistent method of measuring and reporting base station input power and energy efficiency metrics. 1.3 Application This standard is intended to compare the input power and the energy efficiency of functionally similar base stations. Comparisons s
13、hould occur between base stations of the same rated output power class as per 3GPP TS 36.104 3 (e.g., Macro-to-Macro, Micro-to-Micro). Compared base stations should also serve the same number of sectors and have identical rated RF output powers and antenna configurations. For example, a three-sector
14、 base station configured for 2x2 MIMO and 40 Watt RF output power should be compared to another three-sector 2x2 MIMO 40 Watt base station. This standard is not intended to compare the input power and/or the energy efficiency of base stations serving different radio access technologies (e.g., a UMTS
15、 base station should not be compared with an LTE base station). ATIS-0600015.09.2015 2 The defined measurement methods and reported results: Enable fair evaluation of functionally similar base stations from different vendors. Enable base station evaluation under simulated network conditions. Allow v
16、endors to characterize energy improvements as their base station products evolve. Capture the impact of base station energy-saving features. Drive base stations toward sustainable energy-efficient solutions. This document provides a common baseline to compare base station products, and the results s
17、hould not be used for site engineering (e.g., cable sizing, power estimation). End users may request testing to configurations other than those defined within this standard. Customized measurements cannot be reported as an ATIS Base Station Input Power or Energy Efficiency Metric. 2 Normative Refere

27、s a weighted average of five base station input power measurements. Each measurement is made with the base station transmitting at a specific RF load and is evenly weighted based on the standard daily usage model shown in Table 5.1.

ATIS-0600015.09.2015 8 Equation 5.1-1 applies to both integrated and dis
33、tributed base stations. For an integrated base station, the base station input power is the average input power drawn by the base station equipment at the single main location (i.e., location 1).

The environmental conditions under which the base station is tested are defined in
44、 ATIS-0600015 1. However the service provider has the option to request additional base station testing at temperatures other than those specified. For all radio access technologies, testing shall be performed at the center frequency of the applicable downlink bands. The center frequency shall be id
45、entified in the test report. All measured values shall be recorded in the accompanying test report to the accuracy stated in ATIS-0600015 1. A total of 300 continuous samples (taken over 1 second intervals) shall be recorded over the 5 minute measurement period. The recorded base station input power
46、 is the total average input power of the entire base station, and it is based on the measured samples. For an integrated base station, the total input power is the summation of the average power measured at all input voltage ports of the single main location (i.e., location 1). For a distributed bas
47、e station, the total input power is the summation of the average power measured at all input voltage ports of the main location (i.e., location 1) plus the average power measured at all input voltage ports of all remote locations (i.e., location 2, , location N). The recorded base station RF output
48、power is the total average RF output power of the entire base station, and it is based on the measured samples. The total RF output power is the summation of the measured average RF output power at all transmitter antenna connectors at all locations of the base station. The RF output power at each a
49、ntenna connector must be individually measured and recorded. It is not permissible to measure the RF outputs of only one radio unit and assume that all other RF outputs of all other radio units are the same. Once started, the following measurement procedure shall be completed as written without interruption. The procedure shall be conducted simultaneously on all sectors and at all equipment locations.
