The Federal Communications Commission denied to grant Dish Network a preliminary waiver which would have allowed it to move forward with plans to build its own wireless network. Instead, the FCC decided to conduct a formal investigation into Dish's request, a process which could take until the end of the year. Dish wants to do something similar to what LightSquared tried to do: Use traditional satellite spectrum to create a terrestrial wireless broadband network. The FCC granted Dish approval to purchase $3 billion worth of spectrum, but said that a "rulemaking process will best serve the public interest and maximize the long-term value of the spectrum for the American economy." Dish is still hopeful that it will eventually win FCC approval, though the delay is a significant one.
