From the National Journal: Sen. Mark Warner (D-Va.) introduced legislation Friday that would authorize the FCC to hold incentive auctions to free up wireless spectrum.
The auctions would allow license holders to return underused spectrum to the government, freeing the space for other wireless uses.

Federal officials have estimated that such auctions could generation more than $100 billion in revenue over the next five years. While the bill does not specify how the money would be used, Warner said the funds could go toward a combination of causes, including deficit reduction, expanding access to high-speed Internet, or establishing a nation-wide broadband network for emergency responders.
