This is not good news for someone. Perhaps the interference issue is overblown? I believe this is a US-only system.
Link to LightSquared: http://www.lightsquared.com/The problem stems from a recent government decision to let a Virginia company called LightSquared build a nationwide broadband network using airwaves next to those used for GPS.
LightSquared and the FCC both insist the new network can co-exist with GPS systems. But device makers fear GPS signals will suffer the way a radio station can get drowned out by a stronger broadcast in a nearby channel.
