scope:

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 Ω Radio Frequency (RF) connector which allows access to the transmitter output and the receiver input.

Handportable equipment without an external or internal RF connector and without the possibility of having a temporary internal 50 Ω RF connector is not covered by the present document. Integral antenna equipment is covered by EN 300 341-1 [8] (see the corresponding scope).

For combined speech/non-speech equipment the present document is complementary to EN 300 086-1 [7], which covers radio equipment for use in the land mobile service intended primarily for analogue speech.

Radio equipment intended for the transmission of data is covered by EN 300 113-1, EN 300 390-1, and ETS 300 471.

This is a general EN which may be superseded or complemented by specific standards addressing specific applications. It applies to equipment designed to operate within the professional mobile radio service and to the associated frequency planning.

Channel separations, maximum transmitter output/effective radiated power, class of transmitter intermodulation attenuation, temperature ranges and the inclusion of an automatic transmitter shut off facility may be conditions to the issue of a licence by the appropriate Administration.

Additional standards or specifications may also be required for equipment such as that intended for connection to the Public Switched Telephone Network (PSTN).

Requirements to be fulfilled by equipment designed to meet several ETSs/ENs can be found in clause 4.
