Since the Federal Communications Commission switched off analog television signals six years ago, there has been much debate and discussion about the best uses of the frequencies, and when and how auctions should take place. Now there's a proposal to use vacant UHF TV channels for unlicensed TV white space devices and wireless microphones. The CommLaw Blog reports a Notice of Proposed Rulemaking has been filed, with comments on the proposal taken through August 3, 2015; with reply comments due by August 31. Both comments and replies may be filed through the FCC’s ECFS online filing system; refer to Proceeding Nos. 15-146 and 12-268.
