Radio Equipment and Systems (RES); ElectroMagnetic Compatibility (EMC) for Mobile Earth Stations (MES) Used Within Satellite Personal Communications Networks (S-PCN) Operating in the 1@6/2@5 GHz and 2 GHz Frequency Bands
This European Telecommunication Standard (ETS) covers the assessment of Mobile Earth Stations (MES) used within Satellite Personal Communications Networks (S-PCN)@ and ancillary equipment in respect of ElectroMagnetic Compatibility (EMC). Technical specifications related to the antenna port and emissions from the enclosure port of the equipment are not included in this ETS. Such specific technical specifications are found in the relevant product ETS. This ETS specifies the applicable EMC tests the test methods@ the limits@ and the minimum performance criteria for digital radio equipment as defined in ETS 300 733 ?I ETS 300 734 ?I@operating in the frequency ranges 1.6/2.5 GHz and for the associated ancillary equipment. In addition to the technical specification of this ETS@ there may be published in the Official Journal of the European Communities (OJEC) reference to Harmonized EMC standards that apply to the products covered by this ETS their own right@ for example EN 61000-3-3 (power frequency harmonics and voltage fluctuation). This environment classification used in this ETS refers to the environment classification used in the Generic Standards EN 50081-1 [1] and EN 50082-1 [2]@ except the vehicular environment class which refers to ISO 7637-1 [5]. The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus at residential@ commerical@ light industrial and vehicular environments. The levels@ however@ do not cover oxterme cases which may ocur in any location but with a low probability of occurrence. This ETS may not cover those cases where a potential source of interference@ which is producing individually repeated transient phenomena@ or a continuous phenomenon@ is permanently present@ e.g. a radar or broadcast site in the near vicinity. In such a case it may be necessary to use special protection applied to either the source of interference@ or the interfered part@ or both. For a multimode radio station@ this ETS only applies to the radio station when operated in the S-PCN mode. Compliance of S-PCN Mobile Earth Station (MES) radio equipment to the requirements of this ETS does not signify compliance to any requirements related to the use of the equipment (i.e licensing requirements). This ETS is based on the considerations and guidance given in ETR 238 [15].
