FCC OKs Sweeping Spectrum Frontiers Rules To Open Up Nearly 11 GHz Of Spectrum (fiercewireless.com)

Monica Alleven, reporting for FierceWirelessTech: In one fell swoop, the FCC today put the U.S. in a 5G leadership position, voting 5-0 to approve its Spectrum Frontiers proceeding and make spectrum bands above 24 GHz available for 5G. FCC Chairman Tom Wheeler, noting his previous remarks on the proceeding, kept his remarks brief to avoid repeating himself. But he summed it up this way before the final vote: "This is a big day for our nation. This is a big day for this agency," he said. "I do believe this is one of the, if not the most, important decision this agency will make this year. By becoming the first nation to identify high-band spectrum, the United States is ushering in the 5G era of high capacity, high-speed, low-latency wireless networks. By not getting involved in the technologies that will use the spectrum, we're turning loose the incredible innovators of this country," he said. The new rules open up nearly 11 GHz of high-frequency spectrum for mobile and fixed wireless broadband -- 3.85 GHz of licensed spectrum and 7 GHz of unlicensed spectrum. The rules create a new Upper Microwave Flexible Use service in the 28 GHz (27.5-28.35 GHz), 37 GHz (37-38.6 GHz) and 39 GHz (38.6-40 GHz) bands, and a new unlicensed band at 64-71 GHz. The FCC will continue to seek comment on bands above 95 GHz.
