scope:

The present document covers the minimum characteristics considered necessary in order to make the best use of the available frequencies. 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 wideband cordless audio and in-ear monitoring equipment operating in the CEPT recommended band 863 MHz to 865 MHz using analogue frequency modulation. In some countries this equipment may be used in other frequency bands as specified in their national regulations. The present document does not apply to wideband cordless audio or in-ear monitoring systems employing digital modulation, Time Division Multiple Access (TDMA), frequency hopping and spread spectrum or similar forms of modulation.
