Dish Network serves 14 million customers in the United States via a network of owned and leased satellites. The firm spun off its set-top box business, excess satellite capacity, and a handful of additional investments as EchoStar at the beginning of 2008. Dish has purchased wireless spectrum covering the U.S. through a series of transactions. The firm is now seeking ways to put that spectrum to use, potentially via a partnership with an existing carrier. Dish recently dropped a bid to buy additional spectrum from bankrupt LightSquared.
