Foreword This Technical Report (TR) has been produced by ETSI Technic

22、al Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). Introduction The purpose of producing the present document is to lay a foundation for industry to quickly bring innovative and useful products to the market while avoiding any harmful interference with other services and eq

23、uipment. PWMS are intended for use in the entertainment and installed sound industry by Professional Users involved in stage productions, public events, TV programme production, public and private broadcasters installation in conference centres / rooms, city halls, musical and theatres, sport / even

24、t centres or other professional activities / installation. PWMS have traditionally been in use in broadcast bands III, IV and V, since 1957. The transition to digital TV has eroded the availability of spectrum. The growth of theatrical and musical productions along with the requirements of “wireless

25、“ microphones in all forms of media, plus the growth of independent television and film productions, has resulted in the plethora of uses outlined in annex A.1. The Chester conference of 1997 set the spectrum allocation for digital television and simulcasting. There is a danger that this will result

26、 in the displacement of wireless microphones from their traditional spectrum. Continued erosion of spectrum availability will result in the loss of programme, media and film production within Europe, contrary to the EU Recommendation of 50% of all programme making being within the EU. Previous CEPT

27、investigations 9 and 11 identified the frequency range 1 785 MHz to 1 800 MHz, however this designation has proved to have many drawbacks and is not suitable to replace the existing UHF spectrum due to propagation, lack of spectrum for multi-channel use, etc. This frequency range is also being consi

28、dered by ECC for flexible band usage which is incompatible with PWMS usage. ETSI ETSI TR 102 546 V1.1.1 (2007-02) 6 1 Scope The present document describes the requirements for radio frequency usage for PWMS in the frequency ranges up to approximately 1 800 MHz. These systems are constant-carrier dev

29、ices, with 100 % duty cycle, for use by Professional users and are, as a rule, high quality wireless audio transmission systems, including, but not limited to, wireless microphones, back-channel equipment (in-ear monitoring), wireless equipment for sound mixing panels, wireless equipment for news re

30、porting (e.g. news reporters and their teams) and audio link test, correction and optimization equipment. The professional nature of the intended system users differentiates these systems from “consumer“ systems. The present document includes necessary information to support the co-operation between

31、 ETSI and the Electronic Communications Committee (ECC) of the European Conference of Postal and Telecommunications Administrations (CEPT). Additional information is given in the following annexes: detailed market information (annex A); technical information (annex B); expected compatibility issues

32、(annex C); PWMS path loss model (attachment 1); receiver parameters below 1 GHz (attachment 2). 2 References For the purposes of the present document the following references apply: NOTE: While any hyperlinks included in this clause were valid at the time of publication ETSI cannot guarantee their l
