Future Public Land Mobile Telecommunication Systems (FPLMTS) will provide access, by means of one or more radio links, to a range of telecommunication services which are specific to mobile users and to telecommunication services supported by the fixed telecommunication network. FPLMTS are third generation mobile systems which may be terrestrial or satellite based and are scheduled to start service around the year 2000 subject to market considerations. They may be utilized as stand done mobile systems or as part of the fixed network. The frequency bands 1885-2025 and 21 10-2200 MHz have been identified by Radio Regulation WARC-92 (Footnote 746A) for use on a worldwide basis for implementation of FPLMTS. The high level description of FPLMTS and the framework of services are covered in ITU-R Recommendations M.687-1 and M.816 respectively.
