scope:

The present document sets out the minimum performance requirements and technical characteristics of Mobile Earth Stations (MESs) with both transmit and receive capabilities for operation in a 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. If the MES is an element in a multi-mode terminal, unless otherwise stated in the present document, its requirements apply only to the S-PCN MES element of the terminal operating in one or more of the Mobile Satellite Service (MSS) frequency bands given in table 1.
