Last week at the NAB (National Association of Broadcasters) show, FCC head Tom Wheeler pushed broadcasters to loosen their grip on spectrum that the agency plans to auction off to give wireless internet room to grow. Now, hes laid out a draft of the rules for the auction before it takes places next year. The upcoming incentive auction will be a three stage process that, once completed, should open up more wireless spectrum for high-speed services like WiFi and LTE.
