At the Washington Post, Hayley Tsukayama reports that Sprint, which is currently in the process of being purchased by the Japanese wireless company Softbank, is looking to make an acquisition of its own:

Sprint is moving to buy an addition stake in Clearwire, giving it control of the broadband firm.

Sprint already owns 48 percent of Clearwire — a partnership that has allowed Sprint to build out the 4G network it needs to compete with AT&T and Verizon.

If the deal goes through, Sprint’s spectrum holdings would increase dramatically. Yet another example of secondary market transactions being one of the fastest ways to get spectrum to market.
