18、r the Commissions standardisation request C(2015) 5376 final i.1 to provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation of the laws of the Member States relating to the making available on the market of radio equipment and repealing Di
19、rective 1999/5/EC i.2. Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with the normative clauses of the present document given in table C.1 confers, within the limits of the scope of the present document, a presumption of conformity

23、irective 2014/53/EU i.2 (RE Directive) article 3.2 which states 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“. Recital 10 of Directive 2014/53/EU i.2 states that “in order to ensur
24、e that radio equipment uses the radio spectrum effectively and supports the efficient use of radio spectrum, radio equipment should be constructed so that: in the case of a transmitter, when the transmitter is properly installed, maintained and used for its intended purpose it generates radio waves
25、emissions that do not create harmful interference, while unwanted radio waves emissions generated by the transmitter (e.g. in adjacent channels) with a potential negative impact on the goals of radio spectrum policy should be limited to such a level that, according to the state of the art, harmful i
26、nterference is avoided; and, in the case of a receiver, it has a level of performance that allows it to operate as intended and protects it against the risk of harmful interference, in particular from shared or adjacent channels, and, in so doing, supports improvements in the efficient use of shared
27、 or adjacent channel“. Recital 11 of Directive 2014/53/EU i.2 states that “although receivers do not themselves cause harmful interference, reception capabilities are an increasingly important factor in ensuring the efficient use of radio spectrum by way of an increased resilience of receivers again
28、st harmful interference and unwanted signals on the basis of the relevant essential requirements of Union harmonisation legislation“. As a consequence, the present document includes both transmitting and receiving parameters aiming to maximize the efficient use of radio spectrum. ETSI ETSI EN 300 48
29、7 V2.1.2 (2016-11) 7 1 Scope The present document applies to the Receive-Only Mobile Earth Stations (ROMES) radio equipment operating under the Land Mobile Satellite Service (LMSS), in the frequency band 1 518 MHz to 1 559 MHz (space-to-earth bands). The ROMESs operate as part of a satellite system
30、providing one-way data communications. ROMESs could have several configurations, including: either Portable Equipment (PE) or vehicle Installed Equipment (IE); a number of modules including a display/control interface to the user. The present document is intended to cover the provisions of Directive
31、 2014/53/EU i.2 (RE Directive) article 3.2 which states 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“. In addition to the present document, other ENs that specify technical requirem
32、ents in respect of essential requirements under other parts of article 3 of the Directive 2014/53/EU i.2 may apply to equipment within the scope of the present document. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or v
