Microsoft Corporation co-founder Paul Allen founded another company called Vulcan Spectrum LLC. In an auction by the FCC in December 2007, Vulcan Spectrum bought 700MHz spectrum space. But now he decided to sell a large chunk of the spectrum to AT&T, more specifically in sections of Oregon and Washington. AT&T is not disclosing the financial details about the transaction, but AT&T spokesman Michael Coe revealed that the company is making the purchase to meet customer demand and support the transition to LTE.
