Sprint CEO Dan Hesse isn't so narrowly focused as to think that the proposed Clearwire acqusition represents the end of the road for spectrum. Far from it: he tells Bloomberg Businessweek that the company is investigating future airwave deals involving companies and government auctions. The Clearwire deal mostly bought time, according to Hesse. Naturally, these ambitions are partly contingent on both SoftBank's purchase of Sprint and the absence of any Dish-sized hurdles to the Clearwire pact. As long as the path stays clear, though, we wouldn't assume that Hesse's shopping spree is over.
