Globalstar (MSS, ATC, & TLPS)
|
The Globalstar mobile-satellite service (MSS) system uses spectrum in the L and S bands for uplink and downlink transmissions, respectively. Globalstar has been granted authority to utilize portions of its bands for Ancillary Terrestrial Component (ATC) transmissions.
Globalstar's downlink spectrum includes the upper half of Wi-Fi channel 14. In the U.S., use of channel 14 is therefore not allowed. Globalstar had petitioned the FCC to allow it access to channel 14 (including the half outside of its licensed spectrum) to provide its own proprietary "Terrestrial Low Power Service" (TLPS), but it settled for providing this service within its own assignment.
