They were already rolling out their own LTE network so it's no big deal. Lightsquared needed Sprint more than Sprint needed them. Also, let's not forget Sprint will never have a top end network like Verizon or AT&T. I would not ever expect too much from them, I tried Sprint for a month and a half and it was so bad they waived my ETF and ported my number back to AT&T for me. I was really disappointed, I wanted to see them do well and succeed. I see they have this plan called "Network Vision" but it has been a year since they were talking about this and nothing has come to fruition yet. Sure let's celebrate them upgrading cell towers to increase capacity, things they should have done about 4 years or so ago.
Exactly what constitutional right did the FCC violate? To my knowledge, the constitution doesn't give Lightsquared free access to "airwaves" to establish a cellular network.... If those "airwaves" were reserved for satellite signals, Lightsquared had no reason to assume that the FCC would permit use for a cellular network.
