This work item is complementary to the one dealing with S-PCN terminal requirements in the 1,5/1,6 GHz band. This work item is intended to define the minimum requirements and technical characteristics of Network Control Facilities of Satellite Personal Communication Network (S-PCN) operating in the 1,5/1,6 GHz band. NCFs are specified in order to protect other users of the frequency spectrum from unacceptable interference, by ensuring that the network operator is able to suppress and enable the transmissions from the MESs. In particular, these facilities will allow certain interference situations, resulting from the emissions from interfering MESs, to be terminated. This standard can extensively reuse the work already made under ETS 300 735.
