Last week, the FCC issued a spectrum-sharing plan that allows CDMA mobile satellite service (MSS) operators to share certain portions of the identified spectrum (1,610 MHz- 1,625.5 MHz and 2,483.5 MHz-2,500 MHz — collectively known as the Big LEO band) with TDMA MSS operators in the L band, and with fixed and mobile terrestrial operators in the S band.

In the same order, the FCC issued a further notice of proposed rulemaking to explore whether CDMA and TDMA MSS operators could share additional spectrum in the L band.
