Land Mobile Service; Radio equipment using constant or non-constant envelope modulation operating in a channel bandwidth of 25 kHz, 50 kHz, 100 kHz or 150 kHz; Harmonised Standard covering the essential requirements of article 3.2 of the Directive 2014/53/EU
|Publication Date:||1 March 2016|
The present document covers the technical requirements for radio transmitters and receivers used in stations and technical requirements for TMO repeater 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 channel separations of 25 kHz, 50 kHz, 100 kHz and 150 kHz.
It applies to equipment for continuous and/or discontinuous transmission of data and/or digital speech.
The equipment (base station and mobile station) comprises a transmitter and associated encoder and modulator and/or a receiver and associated demodulator and decoder.
The types of equipment covered by the present document are as follows:
• base station (equipment fitted with an antenna connector, intended for use in a fixed location);
• mobile station (equipment fitted with an antenna connector, normally used in a vehicle or as a transportable);
• TMO Repeater; and
• those hand portable stations:
a) fitted with an antenna connector; or
b) without an external antenna connector (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.
Hand portable 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.
These specifications do not necessarily include all the characteristics which may be required by a user of equipment, nor do they necessarily represent the optimum performance achievable.
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.7] and ETSI EN 301 489-5 [i.8]) 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.
