The present document covers the minimum characteristics considered necessary in order to avoid harmful interference
and to make the best use of the available frequencies. It does not necessarily include all the characteristics which may
be required by a user, nor does it necessarily represent the optimum performance achievable.
The present document applies to constant envelope angle modulation systems for use in the land mobile service, using
the available bandwidth, operating on radio frequencies between 30 MHz and 1 GHz, with channel separations of
12,5 kHz, 20 kHz and 25 kHz intended for transmission and/or reception of signals used to initiate a specific response
in the receiver.
The present document applies to non-speech and to the non-speech part of combined speech/non-speech analogue
equipment. In the present document, non-speech radio equipment is defined as a radio equipment transmitting a signal
to initiate a specific response in the receiver. The equipment shall comprise a transmitter and associated encoder and/or
a receiver and associated decoder. The encoder and/or decoder may be a separate piece of equipment, in which case
compliance to the present document covers the encoder and/or decoder in connection with the transmitter and/or
receiver equipment.
In the present document different requirements are given for the different radio frequency bands, channel separations,
environmental conditions and types of equipment, where appropriate.
The types of equipment covered by the present document are as follows:
Base Station: equipment fitted with an antenna socket;
Mobile Station: equipment fitted with an antenna socket;
Handportable stations:
a) fitted with an antenna socket; or
b) without an external antenna socket (integral antenna equipment) but fitted with a permanent internal or a
temporary internal 50 Radio Frequency (RF) connector which allows access to the transmitter ou (... (...abbreviated)
