Satellite Earth Stations and Systems (SES); Harmonized EN for Mobile Earth Stations (MES) providing Low Bit Rate Data Communications (LBRDC) using Low Earth Orbiting (LEO) satellites operating below 1 GHz covering essential requirements under Article 3.2 of the R&TTE directive
This Harmonised Standard will specify the technical requirements that apply to Mobile Earth Stations (MESs) for compliance with article 3.2 of the R&TTE Directive 1999/5/EC. The Mobile Earth Stations (MESs) have the following characteristics: The MESs will operate in frequency ranges below 1 GHz, which are expected to be allocated to Mobile Satellite Data Services operating in bands below 1 GHz, the use of which is expected to be harmonised through implementation of ERC Decisions accordance with the ITU Radio Regulations to the Mobile Satellite Services; The MESs could be either 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; The MESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope of this Harmonised Standard. The requirements of this Harmonised Standard shall be selected to ensure an adequate level of compatibility with other radio services. This Harmonised Standard does not contain any requirement, recommendation or information about the installation of the MESs Compliance of a MES to the requirements of this Harmonised Standard does not imply that the MES may be used. In conformity with Article 3.2 of Directive 1999/5/EC, the use of such equipment may be subject to licensing terms in conformity with Community law.
