The present document is part 2 of a multi-part deliverable covering the International Technical Characteristics and Test Methods, as id
25、entified below: Part 1: “Wireless/Radio Microphones in the 25 MHz to 3 GHz Frequency Range“; Part 2: “Cordless audio and Consumer radio microphones in the 25 MHz to 3 GHz Frequency Range“. The present document was submitted to GSC9 (Seoul, 9 to 13 May 2004) where interested PSOs were requested to ta
26、ke the necessary action to transpose it into their own deliverables for application as appropriate. ETSI ETSI TS 102 192-2 V1.1.1 (2004-08) 7 1 Scope The present document covers the minimum characteristics considered necessary in order to make the best use of the available frequencies. It does not n
27、ecessarily 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 cordless audio and in ear monitoring equipment using either 300 kHz bandwidth analogue modulation or 300 kHz, 600 kHz or 1
28、200 kHz digital modulation. The frequency bands for this equipment may differ from country to country as specified in their national regulations. All equipment is intended to be used with integral antennas. The present document does not apply to broadband modulation such as spread spectrum technique
29、s. Consumer audio equipment intended for audio and voice operating below 50 MHz and using narrow band modulation are excluded from the present document. Electromagnetic Compatibility (EMC) requirements are covered by the present document in annex A. The types of equipment covered by the present docu
30、ment are examples as follows: - cordless headphones; - cordless loudspeakers; - consumer radio microphones; - in-ear monitoring; - in-vehicle cordless; - personal cordless; - broadband multi channel audio systems. 2 References The following documents contain provisions which, through reference in th
31、is text, constitute provisions of the present document. References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
