S-PCN terminals working with Geostationnary Satellites This EN is intended to define the minimum performance requirements and technical characteristics of Mobile Earth Stations (MES) with both transmit and receive capabilities for operation in a Geostationnary Satellite Personal Communication Network (S-PCN). An S-PCN MES may be handheld, portable, vehicle-mounted, host connected, semi-fixed or fixed equipment, or may be an element in a multi-mode terminal; it may consist of a number of modules with associated connections and user interface, or may be a self contained single unit. This EN will specify the requirements of the S-PCN MES element of the terminal operating in one or more of the MSS frequency bands dedicated to geostationnary S-PCNs in the 1,5/1,6 GHz band. The requirements to be defined may cover following two major categories: unwanted emission limits: to protect other radio services from harmful interference generated by the MES in normal use; MES Control and Monitoring Functions (CMF): to protect other radio services from unwanted transmissions from the MES. The CMF in each MES is capable of answering to commands from the Network Control Facilities (NCF) for the operating S-PCN.
