ElectroMagnetic Compatibility and Radio spectrum Matters (ERM); Land mobile service; Technical characteristics and test conditions for radio equipment for analogue and/or digital communication (speech and/or data) and operating on narrowband channels and having an antenna connector

Scope

The present document covers the co-existence requirements for radio transmitters and receivers used in stations in the
Private Mobile Radio (PMR) service. It applies to use in the land mobile service, operating on radio frequencies
between 30 MHz and 3 GHz, with narrow channel separations (CSP) (less than 10 kHz) and intended for speech and/or
data. It is the intention of the present document to cover any Channel Bandwidths (CBW) permitted by CEPT for such
systems e.g. 6,25 kHz.
In the present document different requirements are given for the different radio frequency bands, environmental conditions
and types of equipment where appropriate.
In the present document, data transmission systems are defined as systems which transmit and/or receive data and/or
digitized voice. The equipment comprises a transmitter and associated encoder and modulator and/or a receiver and
associated demodulator and decoder.
The present document covers equipment which may use constant envelope or non-constant envelope modulation.
The types of equipment covered by the present document are as follows:
- base station: equipment fitted with antenna socket;
- mobile station: equipment fitted with antenna socket.
Handportable stations:
a) either 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 RF connector which allows access to the transmitter output and the receiver input.
For the type of equipment defined in b) the following additional measurements are made using the equipment antenna
connected to the station (and not using any connector):
- transmitter effective radiated power;
- transmitter radiated spurious emissions;
- receiver maximum usable sensitivity (field strength);
- receiver spurious radiations.
Handportable station equipment without an external or internal Radio Frequency (RF) connector and without the possibility
of having a temporary internal 50 Ω RF connector is not covered by the present document.
