Re: bent pipe satellites don't work that way
Think I've figured out my confusion. So thinking of Inmarsat's I-series birds where BGAN's L-band but F3 also supplies WAAS using a C-band upllink & L down. Dunno if WAAS is shifting frequencies given I-birds are nearing EOL & moving to Boing's 702SP K+/- broadband sats.
From skimming the C-band alliance's docs, seems like it's mostly TV that'll be affected, and fixable with some guard filters. So bun fighting moves from who can flog spectrum to who pays for those I guess.
