Ultra-High Frequency (UHF) on-board vessels communications systems and equipment - Harmonised Standard covering the essential requirements of article 3.2 of the Directive 2014/53/EU

The present document specifies the minimum technical characteristics required for UHF on board vessels radio
equipment and systems operating on frequencies allocated to the maritime mobile services by the ITU Radio
Regulations [i.1].
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" [i.3].
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of article 3 of the Directive 2014/53/EU [i.3] may apply to equipment within the scope of the present
document.

Ultra visokofrekvenčni (UHF) komunikacijski sistemi in oprema za uporabo na krovu plovil - Harmonizirani standard, ki zajema bistvene zahteve člena 3.2 direktive 2014/53/EU

Ta dokument določa minimalne tehnične lastnosti za ultra visokofrekvenčno (UHF) radijsko opremo in sisteme za uporabo na krovu plovil, ki delujejo prek frekvenc, ki so na podlagi ITU pravilnika o radiokomunikacijah [i.1] dodeljene pomorskim mobilnim storitvam.
Ta dokument vključuje zahteve, s katerimi se dokazuje, da »... mora biti radijska oprema sestavljena tako, da učinkovito uporablja in tudi podpira učinkovito rabo radijskega spektra z namenom preprečevanja škodljivih motenj« [i.3].
Poleg tega dokumenta se lahko za opremo na področju uporabe tega dokumenta uporabljajo tudi drugi standardi EN, ki določajo tehnične zahteve v zvezi z bistvenimi zahtevami iz drugih delov člena 3 Direktive 2014/53/EU [i.3].
