Plus, just to add, the Tlps spectrum isn't anywhere near the Gps spectrum like Lightsquareds' is. Lightsquared is 1525-1559 and GPS is 1559-1610. TLPS is proposed at 2473-2495, and Gsat currently controlls 2483-2500Mhz.

However Gsat carefully crafted its request for nprm last year into two separate parts. One part for Tlps (2473-2495mhz) and a second part for Globalstars controlled "L-band" 1610-1618, which is next to GPS.

So the Fcc issued the "notice" of proposed rule making (NPRM) for Tlps 2483-2495 but not the other portion that Gsat requested. Mr Monroe mentions in the Q&A in the last conference call that they aren't going to pursue the Lband request at this time, which is next to GPS. Don't remember his exact wording but Seeking Alpha does have the transcripts.

The fact that the Fcc didn't shoot down the LBand portion of Gsats request immediately shows that they might be open to it. Perhaps the fcc might be open to gsats request for Lband after what they showed technically in Tlps and Gsats willingness to help technically with interference in the recent 5Ghz issue.

So lightsquared should be compared for the value of the spectrum but perhaps not on the approval of the terrestrial(ground) networks that are proposed,imo.

Spectrum[edit]

LightSquared controls a block of the United States spectrum (1525-1559 MHz) in the L-Band. It received FCC authorization in November 2004 to use this spectrum to build a nationwide 4G-LTE wireless broadband network integrated with satellite coverage.[citation needed] In January 2011, LightSquared received a conditional waiver allowing terrestrial-only use of this spectrum, which would result in a much larger number (40,000) of higher power base stations and present a greater GPS interference problem.[11] The spectrum allocated for the GPS "L1" signal by the FCC is 1559 to 1610 MHz.[14] GPS satellites orbit at an altitude of approximately 20,200 km (12,550 mi).[15]
