The title and reference to the present document are intended to be included in the publication in the Official Journal of the European Union of titles and references of Harmonized Standard under the Directive 1999/5/EC 1. See article 5.1 of Directive 1999/5/EC 1 for information on pres

8、t of standards developed by ETSI and is designed to fit in a modular structure to cover all radio and telecommunications terminal equipment within the scope of the R MES Control and Monitoring Functions (CMF): to protect other radio services from unwanted transmissions from the MES. The CMF in each
9、MES is capable of answering to commands from the Network Control Facilities (NCF) for its S-PCN. NOTE: The requirements for Network Control Facilities (NCF) for S-PCN are contained in EN 301 682 i.2. The determination of the parameters of the user earth stations using a given satellite for the prote
10、ction of the spectrum allocated to that satellite, is considered to be under the responsibility of the satellite operator or the satellite network operators. Figure 1: Void ETSI ETSI EN 301 681 V1.4.1 (2011-11) 81 Scope The present document applies to S-PCN MES for Geostationary mobile satellite sys
11、tems with an EIRP less than or equal to 15 dBW. The present document sets out the minimum performance requirements and technical characteristics of Mobile Earth Stations (MES) with both transmit and receive capabilities for operation in a Satellite Personal Communication Network (S-PCN) in any combi
