Latency will only be an issue where service would otherwise be 
unavailable. Satellite latency is better than no connection at all. The 
bulk of their coverage is with terrestrial stations, but they also have 
a satellite to fill the gaps:

"The nationwide LightSquared network, consisting of approximately 
40,000 cellular base stations, will cover 92 percent of the U.S. 
population by 2015...LightSquared is using terrestrial and satellite 
technology to ensure constant connectivity, regardless of location. The 
LightSquared satellite, built by Boeing, was launched into 
geostationary orbit over North America in November 2010."

Does anyone know the timing synchronization requirements for LTE? This 
network may offer a supplement to current GPS/CDMA based time 
solutions. (says I, trying to get this thread back to time-nuts)
