Mobile-Satellite Service at 1610-1626.5 and 2483.5-2500 Mhz

This Memorandum Opinion and Order (MO&O) affirms the decision in the Report and Order (R&O) in this proceeding to allocate the 1610- 1626.5 MHz (1.6 GHz) and 2483.5-2500 MHz (2.4 GHz) bands for geostationary orbit (GSO) and non-geostationary orbit (low-Earth orbit or LEO) mobile-satellite service (MSS) use, and clarifies that the Commission made no finding in that decision as to whether both types of systems would be authorized. We also clarify the meaning of international footnotes RR753F and RR731E, but defer to the International Telecommunication Union (ITU) 1995 World Radiocommunications Conference (WRC-95) action on modification of these footnotes. Finally, we note that we will explore with the National Telecommunications and Information Administration (NTIA) the possibility of Government or shared Government/non-Government bands being made available to assist in satisfying MSS/radiodetermination satellite service (RDSS) feeder link requirements.
