The modular structure is shown in ETSI EG 201 399 i.1. Figure 1: Void The present document is based on ETSI EN 300 721 6. The requirements of the pres
35、ent document have been selected to ensure an adequate level of compatibility with other radio services. ETSI ETSI EN 301 721 V2.1.1 (2016-05) 7 The present document does not contain any requirement, recommendation, or information about the installation of the MESs. The determination of the parameter
36、s of the user earth stations using a given satellite constellation for the protection of the spectrum allocated to that satellite constellation, is considered to be under the responsibility of the satellite operator or the satellite network operators.

37、The present document applies to Mobile Earth Stations (MES) providing Low Bit Rate Data Communications (LBRDC) using Low Earth Orbiting (LEO) satellites and which have the following characteristics: - the MES could be a Based MES (BMES), a Vehicle mounted MES (VMES), or a Portable MES (PMES); - the
38、MESs operate through satellites in Low Earth Orbit (LEO) as part of a network providing Low Bit Rate Data Communications (LBRDC); - these radio equipment types are capable of operating in all or any part of the frequency bands given in table 1. Table 1: Frequency ranges MES Transmit frequencies and

40、 MSSThe present document is intended to cover the provisions of Directive 2014/53/EU 7 (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 add
41、ition to the present document, other ENs that specify technical requirements in respect of essential requirements under other parts of article 3 of the RE Directive 7 may apply to equipment within the scope of the present document. NOTE 1: A list of such ENs is included on the ETSI web site. NOTE 2:
