Unlicensed

On June 21, 2017, Senate Commerce Committee Chairman John Thune (R-SD) wrote to Federal Communications Commission Chairman Ajit Pai regarding wireless spectrum, writing, "I am pleased to hear that the Commission may be considering a new proceeding to identify new spectrum uses in a range of bands. As you look for ways to better utilize spectrum, I urge you to explore possible new allocations in the mid-band frequencies, perhaps including the 3.7 GHz and 6 GHz bands, and to begin a rulemaking proceeding focused on opening mid-band spectrum for both licensed and unlicensed networks."

On July 18, Chairman Pai responded by saying, "I have asked my colleagues at the Commission's August Open Meeting to initiate a new inquiry into opportunities for next-generation services--particularly wire less broadband services- in the spectrum range of 3. 7 GHz to 24 GHz. This inquiry will be conducted in close coordination with the National Telecommunications and Information Administration, and will focus on exploring opportunities in the mid-band frequencies for expanded flexible use. This inquiry will also explore long-term strategies the Commission can pursue to promote expanded spectrum access to meet the growing demand."

[Commentary] Microsoft recently made a Very Serious Announcement about deploying unused television airwaves to solve the digital divide in America. News outlets ate it up. Here's what's really going on: Microsoft is aiming to be the soup-to-nuts provider of Internet of Things devices, software, and consulting services to zillions of local and national governments around the world.

Microsoft doesn't want to have to rely on existing mobile data carriers to execute those plans. Why? Because the carriers will want a pound of flesh—a percentage—in exchange for shipping data generated by Microsoft devices from Point A to Point B. These costs can become very substantial over zillions of devices in zillions of cities. The carriers have power because, in many places, they are the only ones allowed to use airwave frequencies—spectrum—under licenses from local governments for which they have paid hundreds of millions of dollars. To eliminate that bottleneck, it will be good to have
unlicensed spectrum available everywhere, and cheap chipsets and devices available that can opportunistically take advantage of that spectrum.

Anyone who has spent half a minute working on wireless communications issues knows that America’s wireless providers need additional spectrum to expand existing network capacity and/or deploy new technologies (e.g., 5G). Such constraints apply to both licensed and unlicensed spectrum users. While spectrum isn’t necessarily finite, current technical limitations make it so. This means that there is constant and appropriate pressure on the Federal Communications Commission to identify underutilized spectrum bands and reallocate them for new commercial purposes. Next generation wireless networks will require high, mid and low band spectrum.

While the Commission has taken steps to provide high and low band resources, more attention needs to be paid to the mid bands. So, when presented with a viable proposal that would free spectrum for licensed and unlicensed purposes while protecting or accommodating incumbent licensees, the Commission should grab it with both hands and rejoice. That exact scenario presents itself in the 3.7 to 4.2 GHz and 6 GHz bands. The Commission has the chance to reallocate key bands in a way that would provide needed spectrum for both licensed and unlicensed networks without harming incumbent users. Accordingly, we should tee up the private sector idea outlined above in a quick manner -- whether as part of a longer Notice of Inquiry or a separate, more targeted proceeding -- in the very near future. I, for one, believe doing otherwise would put U.S. spectrum leadership in question and threaten the longevity and viability of America’s broad wireless community.

Microsoft will harness the unused channels between television broadcasts, known as white spaces, to help get more of rural America online.

In an event at the Willard Hotel in Washington, where Alexander Graham Bell demonstrated a coast-to-coast telephone call a century ago, Microsoft plans to say that it will soon start a white-spaces broadband service in 12 states including Arizona, Kansas, New York and Virginia to connect two million rural Americans in the next five years who have limited or no access to high-speed internet. Microsoft’s president, Brad Smith, said white spaces were “the best solution for reaching over 80 percent of people in rural America who lack broadband today.” To support the white-spaces plan, Microsoft is appealing to federal and state regulators to guarantee the use of unused television channels and investments in promoting the technology in rural areas. But the company faces many hurdles with the technology.

Microsoft said its goal was not to become a telecom provider. It will work with local internet service providers like Mid-Atlantic Broadband Communities in Virginia and Axiom Technologies in Maine by investing in some of the capital costs and then sharing in revenue. It has also opened its patents on the technology and teamed with chip makers to make devices that work with white spaces cheaper.

As you may have heard, within the United States we've been working actively to build upon the experience of WRC-15 and towards the decisions to be made at WRC-19. We've recently completed the world's first voluntary incentive auction, making the 600 MHz frequency band available for mobile broadband use, while still ensuring a vibrant broadcasting community.

Together with our neighbors in Canada and Mexico, we have worked to facilitate the success of both the TV and wireless bands and ensured a seamless transition at our shared borders. We applaud the leadership of our counterparts in Mexico and Canada at the ITU and encourage other administrations to consider 600 MHz as they seek additional spectrum for wide-area mobile broadband deployments.

Members of the new Broadband Access Coalition called on the Federal Communications Commission to authorize a new, licensed, point-to-multipoint (P2MP) fixed wireless service in the underutilized 3700 - 4200 MHz spectrum band used primarily by fixed satellite services. The proposed licensing scheme and operating rules enable gigabit and near-gigabit broadband service in rural and underserved areas, and promote competition for broadband delivery among various technologies and licensees.

A broad-based coalition of nonprofit groups [including the Benton Foundation] filed a letter calling on the Federal Communications Commission to reject a proposal from the cellular industry, filed by CTIA on June 16, to re-open and revise the rules finalized more than a year ago for a new Citizens Broadband Radio Service (CBRS) that opens a large frequency band of unused Navy spectrum for small area, high-capacity broadband innovation. The coalition represents consumers, public institutions and small business users of broadband, and includes the Schools, Health & Libraries Broadband Coalition, Next Century Cities, Engine, the R Street Institute, the American Library Association and the National Hispanic Media Coalition. The coalition asks the FCC to instead move rapidly to complete implementation of this historic innovation in spectrum policy, which opens unused military spectrum for sharing with Priority Access Licenses that are available for small areas (census tracts) and short terms, thereby making them more useful and affordable to smaller operators and to venues for indoor use.

What’s the next Wi-Fi frontier? And how can we tap into it for public good? A key band of airwaves that companies are seeking is the unused spectrum in lower frequencies that sit between TV channels. The spectrum in the gaps between bands of airwaves reserved for broadcast television offers prime real estate for companies seeking to bolster connectivity. Those unused bands of airwaves, known as “TV white spaces” (TVWS), are a target for Microsoft in particular. The company recently introduced a program to bring free Internet access to rural families to help bridge the “homework gap” in Charlotte and Halifax counties in southern Virginia.

In 2016, New America’s Open Technology Institute also urged the Federal Communications Commission to allow schools to leverage TVWS to give students lacking broadband at home remote access to the school’s high-capacity broadband, which would be subsidized by the federal E-Rate program.
