As we mentioned in March, Harbinger Capital Partners owns a satellite subsidiary by the name of SkyTerra -- who just so happens to have the spectrum necessary to build a national LTE network. Harbinger wants to go wholesale, proposing conditions to the FCC that would prevent AT&T or Verizon from using the new company's spectrum without FCC approval, or consuming more than 25% of the new network's total traffic. GigaOM's Stacey Higginbotham, who is doing the best job covering this story of anyone we've seen, notes that Nokia has won the $7 billion contract to build the LTE network, now officially named "Lightsquared":As Higginbotham notes, there's a lot of moving parts necessary for success, and the project faces tight spectrum holdings, as well as reliance on (in part) satellite broadband connectivity -- a sector most of our readers know well is littered with failures on the broadband front. Lightquared sent us an e-mail this afternoon claiming the network will consist of approximately 40,000 cellular base stations and cover 92 percent of the U.S. population by 2015. There's more detail at the new Lightsquared website.
