Advocates of 12 GHz for 5G and Broadcasters surprised by FCC notice of inquiry on 12.7-13.25 GHz
FCC Chairwoman Jessica Rosenworcel’s announcement on Monday that the FCC will launch a notice of inquiry on 12.7-13.25 GHz was a surprise to advocates of using 12.2-12.7 for 5G, but doesn’t necessarily have negative implications for a long-awaited order on the lower part of the spectrum range. Supporters of 5G in 12-2-12.7 GHz see it as a positive that Rosenworcel acknowledged that 12 GHz is mid-band spectrum, which the administration identified as critical to 5G. Some refer to the upper section as 13 GHz to avoid confusion with work on the ongoing 12 GHz band.
Rosenworcel said the country needs more mid-band spectrum in the pipeline. “We need to keep up our efforts to find more airwaves to fuel the mid-band spectrum pipeline, following our successful auctions of the 3.45 and 2.5 GHz bands … these are the airwaves that are essential for 5G services to reach everyone, everywhere.”
The most substantial objections are likely to come from broadcasters, though fixed service, satellite and other links are in the band.
NAB (National Association of Broadcasters) was surprised by Rosenworcel’s announcement and hadn’t received any indications from the agency before the speech that it was looking to the 13GHz band, said Robert Weller, Vice President-Spectrum Policy in an interview.
“We’re awaiting the NOI,” he said. TV stations use the band for fixed length transmissions from studio to transmitter, and for relays and electronic newsgathering, he said. “Records at the @FCC show 1,989 broadcast auxiliary authorizations in this band, including 400 ENG authorizations,” Weller tweeted Tuesday.
“The NOI (Notice of Inquiry), if adopted, would provide an opportunity for all stakeholders to provide information and views well in advance of any policy proposal,” said an FCC spokesperson.
“The FCC, on a bipartisan basis, recognizes we need more mid-band spectrum freed up for 5G,” said an industry expert active in the proceeding.
A top DOD official noted the difficulty of clearing the 3.1-3.45 GHz band, the top candidate band for 5G, experts said. They predicted analysis of the 13 GHz band would likely take several years.
“While certainly giving credit for recognizing the need to act on new commercial mid-band spectrum, the focus on the upper 12 GHz is a bit puzzling because an NOI could take years and lower 12 GHz is essentially ready to go,” former Commissioner Mike O’Rielly told us. “I have to hope yesterday’s announcement is part of a multipronged band identification and reallocation effort to be released soon, coupled with definitive action on lower 12 and lower 3 GHz,” he said. “The only mid-band spectrum that is available to be put to use quickly is 12.2 to 12.7,” said Jeff Blum, Dish Network executive vice president-external and legislative affairs. “We continue to urge the FCC to unleash that band for 5G to help Dish compete in the wireless market while protecting incumbent operations from harmful interference,” he told us. “It’s very encouraging for us in the 12 GHz band to see the commission recognizing the value of bringing mid-band spectrum in the 7-16 GHz range to the U.S.’s spectrum pipeline,” said RS Access CEO Noah Campbell. The lower 12 GHz band “is very unique, and it’s very important for continued U.S. 5G leadership,” he said. “The opportunity to create a 1,000 MHz block between 12.2 and 13.2 is extremely compelling,” he said.
The Rosenworcel comments show the FCC won’t act before it’s ready on 12 GHz, said Digital Progress Institute President Joel Thayer. “The chairwoman is standing with the FCC’s engineers and not bending to political pressure,” he said. “This proceeding has been unnecessarily politicized and this move sends a clear message that the engineering and FCC procedure will be the determining factor here, not corporate lobbying.” In a white paper last year, IEEE said the 13 GHz band “could be considered as a future candidate for unlicensed use due to its allocation to the same types of incumbents as the recently opened 6 GHz band.” IEEE found little interference risk. “The demand for unlicensed spectrum will continue to increase in the next years, it is necessary to study potential new bands to accommodate new technologies and services in the mid-band spectrum,” the report said.
Author’s Comment:
We’ve posted two articles on the battle for 12 GHz spectrum policy (see References below). It’s important that the FCC is proposing 12GHz for 5G despite that frequency band NOT included in revision 6 of ITU M.1036 Frequency Arrangements for IMT (and in particular for 5G).

It will be interesting to see how this spectrum will be used. Given the high-frequency, it will most likely have to be for line-of-sight applications, unless the power is cranked way up. If it is for unlicensed application, will it primarily be used in Wi-Fi access points? Will it be used as a wire replacement in the home? One would think that the Studio-to-Transmitter use-cases are becoming less important, as cellular data solutions have become an alternative for electronic news gathering and will just keep getting better.
Regarding the comment about the ITU, it seems like the FCC views its work as irrelevant to the needs of the U.S. marketplace.
