Price from:
€ 19.50


Harmonized under:
  • Directive 2014/53/EU of the European Parliament and of the Council of 16 April 2014 on the harmonisation of the laws of the Member States relating to the making available on the market of radio equipment and repealing Directive 1999/5/EC Text with EEA relevance

Harmonized standards:


The present document covers the technical 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 National
Administrations for such systems, e.g. 6,25 kHz.
Table 1: Radiocommunications service frequency bands
Radiocommunications service frequency bands
Transmit 30 MHz to 3 000 MHz
Receive 30 MHz to 3 000 MHz
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 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 connector;
- mobile station: equipment fitted with antenna connector.
Handportable stations:
a) either fitted with an antenna connector; or
b) without an external antenna connector 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.
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.
The present document contains requirements to demonstrate that "... Radio equipment shall be so constructed that it
both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference" and that
"....radio equipment supports certain features ensuring access to emergency services" [i.3].
In addition to the present document, other ENs (e.g. ETSI EN 301 489-1 [i.4] and ETSI EN 301 489-5 [i.5]) that specify
technical requirements in respect of essential requirements under the Radio Equipment Directive [i.3], may apply to
equipment within the scope of the present document.
