Parts of the 5GHz band present a "terrific near-term opportunity" to add Wi-Fi spectrum, Rosenworcel said. "We should move beyond old dichotomies that pit licensed versus unlicensed spectrum," she said. "Because across the board we need to choose efficiency over inefficiency and speed over congestion. Because we can take steps that inspire innovation and meet the growing demand for wireless services -- or we will fall behind."
Rosenworcel also called on the FCC to consider opening up parts of lower bands to unlicensed Wi-Fi, including parts of the 600MHz band now controlled by U.S. television stations. That spectrum, eyed by carriers as some of the best available for mobile broadband service, is scheduled to be auctioned by the FCC in mid-2015.
