Foreword This Technical Report

27、 (TR) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). A future ETSI Technical Specification on the recommended spectrum access technique in the present document is planned as well as tests on a demonstrator built to the specifications in

28、the TS. An ETSI Technical Report on the defined RF compliance tests carried out on the demonstrator for the selected spectrum access mechanism defined in the TS is planned to be prepared. Please note that although the technology demonstrator will concentrate on one particular application, the techno

29、logy will ultimately be transferable to other PMSE applications. Introduction Radio microphone devices use 100 % duty cycle to convey voice or music either for a live event such as concerts and theatres or for a recorded event such as the production of film and television programs. Interference duri

30、ng this process is not only commercially disastrous; it can be also harmful to the audience where a public address system is in use. The regulations governing the operation of PMSE (Program Making and Special Events) systems are currently in flux in Europe. During the process of changeover compressi

31、on of the television channels is taking place below 790 MHz. The spectrum between 790 MHz and 862 MHz has been considered a Digital Dividend and allocated for use by Electronic Communications Networks. This has resulted in a reduction of spectrum available for PSME. Protection PMSE devices use very

32、low radiated power levels (the maximum PWMS RF power level is 50 mW) in comparison to most other radio communication systems. In order for them to function properly, they are protected from interference. Up to now this has not been a problem since PMSE equipment operated in locally unused TV channel

33、s that presented a very predictable RF environment. In the future, many different kinds of new devices, the characteristics of which are difficult to fully anticipate at this time, may be sharing this space. Some of these devices will be used for broadband data, and will occupy any spectrum which is

34、 available to them, i.e. from a few MHz to a multiple of 10 MHz. Other uses of the Digital Dividend, which may eventually go down to 600 MHz, are use by the emergency services and other mobile services. The question of how to protect PMSE equipment from interference caused by new devices has been th

35、e subject of much discussion and debate. Traditionally, incompatible radio communications systems were assigned to operate in separate frequency bands, but this scheme is becoming impractical in todays world of intensive spectrum use. A more dynamic and robust solution is needed. ETSI ETSI TR 102 79
