Spectrum Sharing among NGSO-MSS (Big LEO) Systems in 1.6/2.4 GHz bands
In June 2004, the Commission by a Report and Order and Further Notice of Proposed Rulemaking adopted a spectrum sharing plan for low earth orbit satellite systems in the 1.6 GHz and 2.4 GHz bands (Big LEOs). The spectrum sharing plan will further the Commission's goal of efficient spectrum utilization by increasing the number of providers offering services to consumers over the same spectrum, and will promote the deployment of more innovative services to consumers. Specifically, in the 1.6 GHz or "L-band," mobile-satellite service (MSS) operators with satellite systems that utilize code division multiple access (CDMA) and time division multiple access (TDMA) technologies will share 3.1 megahertz of spectrum at 1618.25-1621.35 MHz. In the 2.4 GHz or "S-band," the Commission allocated the 2495-2500 MHz band to fixed and mobile except aeronautical mobile services, in order to provide additional spectrum to the 2500-2650 MHz band to accommodate the relocation of MDS channels 1 and 2 under a band plan adopted in a companion item in WT Docket No. 03-66 (FCC 04-135). CDMA MSS will continue to be permitted to operate in the 2495-2500 MHz band on a shared basis.
