Kevin Werbach points to a troubling factor of the FCC's recent decision to add more spectrum to the unlicensed 5 MHz band: The spectrum was freed up due to a compromise with military users, and the deal was done behind closed doors with private interests represented by a few large companies, Werbach says. He's concerned that rules around use of that band, which aren't clear yet, might hamper potential innovation there.
Werbach also notes that this new spectrum won't do much to help out last-mile access because the high frequency impedes running signals quite as far as the 2.4 GHz and other lower frequencies.
