The financial and technological proposals are incredibly complicated, but they provide the kinds of details that broadcasters have wanted to see before they decide whether to let the federal government auction to broadband providers some of the airwaves now used for TV. The process being circulated by FCC Chairman Tom Wheeler includes a reverse auction, where station owners would indicate how much cash they want for their spectrum and can drop out if the bidding is too low. There’s also a forward auction, where wireless companies would raise their offers in successive rounds. When it’s all done, the FCC will repack the spectrum — making usage efficient by assigning new channels to the broadcasters who stay on the air. There’s also a plan to accommodate low-power TV, translators, and wireless microphones that will be affected by the changes. “Whether television broadcasters participate in the Incentive Auction will be purely voluntary, but participation in the Incentive Auction does not mean they have to leave the TV business,” Wheeler says in a blog post. “New channel-sharing technologies offer broadcasters a once-in-a-lifetime opportunity for an infusion of cash to expand their business model and explore new innovations, while continuing to provide their traditional services to consumers. We will ensure that broadcasters have all of the information they need to make informed business decisions about whether and how to participate.” The plan would make additional spectrum available for WiFi.
