This week we welcome Gigi Sohn, Counselor to Chairman Wheeler of the Federal Communications Commission, to Community Broadband Bits for episode 192. Before joining the FCC, Gigi was a founder of Public Knowledge.

Gigi discusses the pro-competition agenda that Chairman Wheeler has advanced, including the efforts to ensure communities can decide locally whether to build a municipal network or partner. We also discuss other elements of FCC action to encourage competition in the Internet access market, even how television set-top boxes fit in.

Echoing some of the comments I regularly hear from some thoughtful listeners, I asked if competition was the best approach given the argument that telecom, and particularly fiber, has the characteristics of a natural monopoly.

The transcript from this episode is available here.

After reading "Amtrak's Lessons for Access to the Airwaves," I knew we wanted to talk to Michael Calabrese and Patrick Lucey of the Open Technology Institute at the New America Foundation to discuss wireless policy. Unfortunately, scheduling challenges kept Patrick off the this show but we do have a great discussion for this week's Community Broadband Bits podcast with Michael Calabrese, who runs the Wireless Future program at OTI.

We discuss the wireless technology Amtrak has wanted to deploy and alternatives that would have been less costly and more quickly to implement. However, this is really just an opportunity to begin the larger discussion about where wireless is going.

We also talk about a recent FCC decision to create much more shared spectrum and how the new system will work, which was also described in a presentation by Milo Medin at the 2015 Freedom to Connect event.

If you enjoy this discussion, you may be interested in our previous discussions with Dewayne Hendricks.

On April 17th, FCC Commissioners voted unanimously to expand the use of spectrum previously reserved for U.S. Army and Navy radar systems. The FCC Report and Order creates the Citizens Broadband Radio Service (CBRS) which establishes rules for shared use by licensed and unlicensed users.

This is a step forward to ensuring we are getting the most use out of the spectrum - by allowing different entities to share the spectrum when it is not being used in some geographic areas for the purpose it was originally allocated for. Milo Medin of Google explained this plan at Freedom to Connect - watch his presentation here.

According to the FCC Press Release [PDF], sharing will be managed with a three-tiered approach:

In addition to the protected incumbent tier, the Report and Order authorizes two commercial tiers of use in the Citizens Broadband Radio Service. The General Authorized Access tier, which allows any user with a certified device to operate without seeking any further Commission approval, will permit low-cost entry into the band, similar to unlicensed uses. A Priority Access tier will make geographically targeted, short-term priority rights to a portion of the band available through future spectrum auctions. One or more Spectrum Access Systems, operated by private commercial entities, will facilitate coexistence among the different user tiers.

Public Knowledge applauded the decision. Senior Vice President Harold Feld:

Today’s FCC’s actions lay the groundwork for changes in the very way we use wireless, allowing different levels of interference protection and network architecture that will make the wireless world of the future as radically different as the smartphone and the WiFi hotspot are from touchtone phones and the CB radios.

New America's Michael Calabrese, Director of New America's Wireless Future Project commended the FCC and pushed for more action:

The Institute for Local Self Reliance has joined with Public Knowledge, Common Cause, and the Open Technology Institute, in submitting reply comments to the FCC last week as the Public Interest Spectrum Coalition (PISC). The issue at hand is the FCC’s proposal of new rules for how to govern the 3.5 GHz band, a range of the electromagnetic spectrum useful for many different types of communication. 

The PISC comment focused on the importance of getting away from the long-standing FCC policy of simply auctioning off big slices of spectrum for telecom companies to use exclusively, which inhibits innovation and enables a monopolization of the communications marketplace. Verizon and AT&T, who hold licenses to large swathes of the spectrum already, are lobbying to FCC to keep the status quo in place. PISC (and ILSR) support a more open arrangement, allowing multiple users to share the same underutilized spectrum segment, while still avoiding interference. The full text of the comment is available here. 

The language and policy of spectrum management can seem arcane to people unaccustomed to it, but how we regulate and use the electromagnetic spectrum has wide ranging consequences for almost all the technology we use in our daily lives. For a general primer on the importance and possibilities of a more open spectrum licensing policy, see the wireless commons articles we published earlier this summer.

In the first part of this series, we discussed how spectrum could be better managed to allow far greater communications capacity, but only if the FCC abandoned its traditional approach of auctioning spectrum to carriers for monopolistic use. In this part, we’ll discuss how devices could take advantage of a new approach to spectrum management and how it might help to circumvent gatekeepers, whether corporate or government.

With increased unlicensed use of the spectrum, an astonishing range of possibilities emerges. Mobile devices could communicate with each other directly, without reference to a central node controlled by a telecom company or monitored by a government. Access points could be strung together wirelessly to create decentralized ad hoc networks, with each device forwarding data from every other, creating a seamless network throughout an entire neighborhood or city. Commotion Wireless is already attempting this on a small scale with just the existing spectrum.

Such networks already exist in a few places, but access to more unlicensed spectrum and permission to use stronger signals would allow them to grow, potentially creating a more decentralized and democratic way to share information and access the internet; an end-run around data caps, future “fast lane” policies, and other drawbacks of relying on one or two telecom oligopolists as a network owner and gatekeeper.

Another exciting possibility for unlicensed spectrum use can be found in emerging Ultra-Wide Band technologies. These allow devices to use a large swath of spectrum at very low power to send information in bits and pieces over short distances, somewhat similar to bitTorrents, and could allow for nearly instantaneous exchange of gigabits of data. All of this is dependent, however, on access to spectrum with the right characteristics, such as low frequency TV bands that can penetrate physical obstacles like walls or trees especially well.

These technologies have political ramifications as well. Rather than having to make monthly payments to a national provider as you do with your cell phone, we would have different models to choose from. Some would be just a matter of buying the right device,... Read more

This is the first in two-part series on spectrum basics and how we could better manage the spectrum to encourage innovation and prevent either large corporations or government from interfering with our right to communicate. Part 2 is available here.

We often think of all our wireless communications as traveling separate on paths: television, radio, Wi-Fi, cell phone calls, etc. In fact, these signals are all part of the same continuous electromagnetic spectrum. Different parts of the spectrum have different properties, to be sure - you can see visible light, but not radio waves. But these differences are more a question of degree than a fundamental difference in makeup. 

As radio, TV, and other technologies were developed and popularized throughout the 20th century, interference became a major concern. Any two signals using the same band of the spectrum in the same broadcast range would prevent both from being received, which you have likely experienced on your car radio when driving between stations on close frequencies – news and music vying with each other, both alternating with static. 

To mitigate the problem, the federal government did what any Econ 101 textbook says you should when you have a “tragedy of the commons” situation in which more people using a resource degrades it for everyone: they assigned property rights. This is why radio stations tend not to interfere with each other now.

The Federal Communications Commission granted exclusive licenses to the spectrum in slices known as bands to radio, TV, and eventually telecom companies, ensuring that they were the only ones with the legal right to broadcast on a given frequency range within a certain geographic area. Large bands were reserved for military use as well.

Originally, these licenses came free of charge, on the condition that broadcasters meet certain public interest requirements. Beginning in 1993, the government began to run an auction process, allowing companies to bid on spectrum licenses. That practice continues today whenever any space on the spectrum is freed up. (For a more complete explanation of the evolution of licensing see this excellent Benton foundation blog post.)

Although there have been several redistributions over the decades, the basic architecture remains.... Read more

The FCC is now contemplating how much newly freed spectrum to retain for public use and how much to auction off to private companies for their exclusive use. Public Knowledge is leading the effort to ensure we retain enough shared spectrum to unleash more innovation and public benefits rather than simply padding the profits of a few massive firms that already control plenty of it.

In addition to the Gigabit Libraries Network's White Spaces Pilot Project, we have shared white space technology stories from North Carolina and New York

Public Knowledge recently created a video on the prevalence of spectrum in our lives, included below. Most of us take for granted the fact that shared (or unlicensed) spectrum permeates our culture. 

Instead of sitting by while the resource is auctioned off to the highest bidder, Public Knowledge has also created a petition to retain the spectrum needed for white space technology to spur more innovation. From the petition:

One of the most promising new technologies uses the empty spaces between television channels, the so-called "TV white spaces" (TVWS). The United States currently leads the world in this new technology. In the few short years since the FCC approved use of the TVWS, companies have built and shipped equipment to bring needed broadband to rural communities, creating jobs and expanding opportunities.

...

We call on the FCC to set aside 4 reclaimed TV channels, or 24 MHz, for TV white spaces. This will still leave the FCC more than enough to auction to wireless companies for their commercial needs. By reserving 24 MHz of "unlicensed" spectrum across the country for TV white spaces, the FCC will encourage further innovation in wireless services and foster the growth of next generation WiFi contributing billions of dollars in new products and consumer savings.

When it comes to building a community owned wireless network, few have more experience than Matthew Rantanen, our guest for the Community Broadband Bits podcast this week. Rantanen has an impressive list of titles, two of which are Director of Technology for the Southern California Tribal Chairmen's Association (SCTCA) and Director of the Tribal Digital Village Initiative.

We discuss the need for better network access on reservations generally and how several reservations in southern California were able to build their own wireless networks using unlicensed spectrum and the power of the sun. This success has inspired others, including in Idaho, to take similar approaches to ensure modern connectivity.

We also discuss the importance of unlicensed spectrum to ensure that underserved communities can build the networks they need without having to ask for permission and the role that Native Public Media plays in expanding access to media across North America.

Wireless networks have been incredibly successful, from home Wi-Fi networks to the billions of mobile devices in use across the planet. So successful, in fact, that some have come to believe we no longer need wires.

We developed this fact sheet to clarify some misconceptions about what wireless Internet networks are capable of and the importance of fiber optic cables in building better wireless networks as our bandwidth needs continue to increase.

This fact sheet defines important terms, offers some key points clarifying common misconceptions, compares 4G and 3G wireless to wired cable, and more. We also include references to additional resources for those who want to dig deeper.

Have you heard of the National Information Infrastructure, or the NII? Most of us either haven't, or have forgotten we once knew what it could be. Dewayne Hendricks joins us to remind us what it was and why we should care. It's "kind of a big thing." Since we conducted this interview, unlicensed spectrum issues became a hot topic; listen below to get a better sense of just how important this issue is.

In our discussion, Dewayne walks us through the original vision, one that now seems fanciful: a world of mobile devices that interconnect with each other on the wireless networks that surround us. While we do have wireless networks in most places, they are often controlled by a few companies, like Verizon and AT&T, that restrict how we can use them and how our devices can talk to each other.

But the NII was to be more decentralized, creating much more space for entreprenuers and innovators to create new business models. A few massive corporations were able to change that vision, creating a lucrative role for themselves as gatekeepers along the way.

Dewayne started this conversation by recommending a 1995 filing by Apple [pdf]. Whether you read it before or after our conversation, it is worth taking a look.

Dewayne has previously joined us to discuss wireless generally and then later to talk about the wired vs. wireless debate. A previous interview with Bruce Kushnick is also referenced over the course of this interview.
