2、EMC requirements for telecommunication network equipment (1 GHz-6 GHz) Summary Recommendation ITU-T K.80 presents electromagnetic compatibility (EMC) requirements for telecommunication equipment in the frequency range between 1 GHz and 6 GHz. Source Recommendation ITU-T K.80 was approved on 14 July

3、2009 by ITU-T Study Group 5 (2009-2012) under Recommendation ITU-T A.8 procedures. Keywords EMC, protection. ii Rec. ITU-T K.80 (07/2009) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communicatio

4、n technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World

5、 Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In s

6、ome areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recogni

7、zed operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The word

8、s “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that

9、the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendatio

10、n development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are

11、 therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2010 All rights reserved.

13、n equipment contained in Recommendations ITU-T K.48 and ITU-T K.76, specifying requirements for phenomena at frequencies between 1 GHz and 6 GHz. Telecommunication equipment can be influenced or can influence the electromagnetic environment at frequencies between 1 GHz and 6 GHz. The need to analyse

14、 this frequency range was highlighted due to the use of radio devices in this frequency range, including mobile phone IMT-2000, wireless LAN and broadband access radio equipment. The requirements given in specific product family Recommendations supersede those given in this Recommendation. Rec. ITU-

15、T K.80 (07/2009) 1 Recommendation ITU-T K.80 EMC requirements for telecommunication network equipment (1 GHz-6 GHz) 1 Scope This Recommendation is applicable to telecommunication equipment and considers electromagnetic emission and immunity phenomena at frequencies between 1 GHz and 6 GHz. EMC emiss

16、ion phenomena below 1 GHz are covered by ITU-T K.48 and ITU-T K.76. EMC immunity phenomena below 2 GHz are covered by ITU-T K.48 and ITU-T K.76. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of th

All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendations and othe
