ETSI EN 300 422-1:2008 Electromagnetic compatibility and Radio spectrum Matters (ERM); Wireless microphones in the 25 MHz to 3 GHz frequency range; Part 1: Technical characteristics and methods of measurement (V1.3.2)
The present document covers the minimum characteristics considered necessary in order to make the best use of the available frequency spectrum for wireless microphones. The present document specifies the minimum performance requirements and the methods of measurement of Assistive Listening Devices@ radio microphones and in-ear monitoring systems. It does not necessarily include all the characteristics that may be required by a user@ nor does it necessarily represent the optimum performance achievable. The present document applies to equipment operating on radio frequencies between 25 MHz and 3 GHz (as shown in table 1) using analogue@ digital and hybrid (using both analogue and digital) modulation. The present document does not apply to radio microphones or in ear monitoring equipment employing Time Division Multiple Access (TDMA) modulation. The maximum power recommended for equipment covered by the present document is 250 mW (erp below 1 GHz and eirp above 1 GHz). Equipment above 250 mW should be tested to EN 300 454-1 [6]. The present document also covers radio microphones used in the 863 MHz to 865 MHz band@ with a maximum power of 10 mW. Electromagnetic Compatibility (EMC) requirements are covered by EN 301 489-9 [7]. National regulations on maximum power output will apply or those detailed in the latest version of CEPT/ERC/REC 70-03 [11]. The classes of equipment given in the present document are as follows: - class 1 equipment would normally be considered as a category requiring an operator licence; - class 2 equipment would be considered in some countries as not requiring an operator licence. The types of equipment covered by the present document are as follows: ? professional hand held radio microphones; ? professional body worn radio microphones; ? in ear monitoring systems; ? consumer radio microphones; ? tour guide systems; ? and Assistive Listening Devices (Aids for the handicapped).
