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,...

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....

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.

Remember that Washington Post story about bigger, free Wi-Fi networks? It went hugely viral with all manner of outlets picking the story up, unintentionally distorting it, and amplifying it.

Some good has come of it. For one thing, I was reminded that Ars Technica does a really good job of tech reporting, better than anyone else in my estimation. Cecilia Kang offered a follow-up story to clarify the original that should help more people to understand what is at stake.

But more importantly, we saw a lot of media coverage about something really important, whether we allocate future spectrum for everyone to use (much like Wi-Fi) or will we reserve it just for AT&T, Verizon, or another big corporation?

Harold Feld has a strong opinion on the matter:

This past week, we’ve had quite the discussion around Cecilia Kang’s WashPo piece describing a plan by the FCC to create a national WiFi network by making the right decisions about how to allocate spectrum between licenses for auction and what to leave available for the unlicensed TV white spaces (“TVWS” aka “Super WiFi” aka “Wifi on steroids”). As Kang describes, the FCC’s opening of sufficient spectrum for TVWS could lead to “super WiFi networks (emphasis added) around the nation so powerful and broad in reach that consumers could use them to make calls or surf the Internet without paying a cellphone bill every month.”

Needless to say, the article faced much pushback, despite a subsequent Washpo clarification to indicate the FCC was not, actually, planing to build a network. Amidst the various critics, there were some general defenders of the concept. My colleagues at EFF noted that increasing the availability of open spectrum for WiFi-type uses , and my friends at Free Press argued that such a free public wifi network (or, more accurately, series of...

One hundred years after Teddy Roosevelt and AT&T agreed to the Kingsbury Commitment, Harold Feld joins us on Community Broadband Bits podcast to explain what the Kingsbury Commitment was and why it matters. In short, AT&T wants to change the way telecommunications networks are regulated and Harold is one of our best allies on this subject.

AT&T is leaning on the FCC and passing laws in state after state that deregulate telecommunications. Whether we want to deal with it or not, these policies are being discussed and consumer protections thus far have taken a beating. This interview is the first of many that will help us to make sense of how things are changing and what we can do about it.

We also discuss the ways in which the Federal Communications Commission and Federal Trade Commission spurred investment in next-generation networks by blocking the AT&T-T-Mobile Merger on anti-trust grounds.

Harold is senior Vice President of Public Knowledge and writes the Tales of the Sausage Factory blog.

Dewayne Hendricks is a serial entreprenuer, innovator, and wireless expert. Wired magazine labeled him a broadband cowboy back in 2001. And he is our guest on the 18th episode of Community Broadband Bits.

Our discussion focuses on the promise of wireless technologies and how a few entrenched interests in DC (the big broadcasters and wireless telephone companies like AT&T) are preventing innovative approaches that would dramatically improve the capability of all our modern technologies.

Hendricks is a prolific tweeter that comes highly recommended from us. And he has kindly recommended two papers readers may want to read following our conversation: David Weinberger's "The myth of interference" and Paul Baran's "False Scarcity" [PDF].

We look forward to inviting Dewayne back soon to discuss the Fiber versus Wireless debate. Let us know if you have any other questions we should ask when he returns!

Once again, we are witnessing the federal government allowing a few massive telecommunications companies to collude rather than compete. Verizon is about to ally itself with major cable companies, to the detriment of smaller competitors in both wireless and wireline.

One of the reasons we so strongly support the right of communities to decide locally whether a community network is a smart investment is because the federal government does a terrible job of ensuring communities have fast, affordable, and reliable access to the Internet. By building their own networks, communities can avoid any dependence on the big cable or telephone companies that are more interested in consolidating and boosting shareholder dividends than they are in building the real infrastructure we need.

The Department of Justice released a statement on August 16th, that it will allow the controversial Verizon/SpectrumCo deal to move forward with changes. We have watched this deal, bringing you you detailed review and analysis by experts along with opinions from those affected. One week later, the slightly altered deal was also blessed by the FCC.

Many telecommunications policy and economic experts opposed the deal on the basis that it will further erode the already feeble competition in the market. In addition to a swap of spectrum between Verizon and T-Mobile, the agreement consists of side marketing arrangements wherein Verizon agrees not to impinge in the market now filled with SpectrumCo (Comcast, Time Warner Cable, Cox, and Bright House Communications).

Verizon has been accused of hoarding spectrum it doesn't need. The marketing arrangements constitute anti-competitive tools that the DOJ has decided need some adjusting. From the announcement:

The department said that, if left unaltered, the agreements would have harmed competition by diminishing the companies’ incentive...

In December, 2010, Verizon Wireless began operating its network via C-Block spectrum with licenses it acquired in the 2008 auction. In keeping with net neutrality rules unique to C-Block usage, Verizon agreed long ago that it would not block or limit consumers' ability to tether on their 4G LTE network.

Tethering allows a consumer to use a device, such as a smartphone, as a modem to funnel Internet access to an additional device. On July 31, the FCC agreed to end an investigation into whether or not Verizon Wireless had violated this rule. In exchange, Verizon Wireless would make a $1.25 million "voluntary contribution."  Verizon Wireless did not admit it broke the rules. The FCC's consent decree requires the practice cease and that Verizon Wireless implement policies to curtail the behavior.

The story began in 2011. Verizon Wireless began charging its customers an addition $20 per month to allow them to tether additional devices to their smartphones and called the feature "Mobile Broadband Connect."

The Free Press filed a complaint. The FCC began their investigation in October, 2011. From the Free Press website:

Free Press argued that by preventing customers from downloading these applications that allow customers to use their phones as mobile hotspots, Verizon violated conditions of its 700 MHz C Block licenses, the spectrum in which Verizon operates its LTE service. When Verizon purchased the licenses, it agreed to abide by conditions that it not “deny, limit or restrict” its customers’ ability to use the applications or devices of their choosing.

The company also asked the Google Play Store store to block Verizon Wireless customers from accessing software that would enable tethering. Google complied with the request, even though it has often advocated for net neutrality, but were not investigated because they are not an ISP.
