Sistemet dhe Stacionet Satelitore në Tokë (SES); Standard i harmonizuar për Stacionet Tokësore të Lëvizshëm (MES) që sigurojnë Komunikim të të Dhënave me Vlerë të Ulët të Biteve (LBRDC) duke përdorur satelitë me Orbitë Tokësore të Ulët (LEO) që punojnë në bandat e frekuencave nën 1 GHz që mbulon kërkesat thelbësore të artikullit 3.2 të Direktivës 2014/53/EU

Satellite Earth Stations and Systems (SES); Harmonised Standard for Mobile Earth Stations (MES) providing Low Bit Rate Data Communications (LBRDC) using Low Earth Orbiting (LEO) satellites operating below 1 GHz frequency band covering the essential requirements of article 3.2 of the Directive 2014/53/EU

Scope

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 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.

The 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 addition 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: The MESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the
scope of the present document.
