Rural tribal communities in the U.S. struggle with some of the worst connectivity in the country. Decades of neglect have put them even farther behind other rural communities, many of which are moving toward community networks rather than depending on national Internet access providers. The most isolated tribal community in the continental United States has chosen to shrink their disadvantages by establishing a community network.

Within the Canyon

The Havasupai Indian Reservation, home to about 600, is surrounded by the Grand Canyon National Park in Arizona. Having populated the region for centuries, the federal government restricted them to the reservation, an area of about 518 acres in Havasu Canyon, in 1882. Non-Indian ranchers, settlers, and miners started takng over the area in the 1870s and Executive Order confiscated the Havasupai homelands for public use. After the establishment of the Grand Canyon National Park and generations of persistence, the tribe finally won back more than 188,000 areas of plateau and canyon lands in 1975 through an Act of Congress.

The community, on the floor of the Grand Canyon, can only be reached by helicopter, or an 8-mile hike that starts 67 miles away from the nearest town. Mail is still delivered by mule.

Seeking Spectrum

That persistence is paying off again as the Havasupai Tribal Council focuses their attention on broadband access. They're collaborating with nonprofit MuralNet to connect the main residential area in Supai, where about 450 tribal members live. The nonprofit's mission is to assist tribes like the Havasupai develop infrastructure to obtain high-speed Internet access. 

Protestors around the country have taken a stand against 5G ⁠— often based on myths of health effects from the new technology. But Doug Dawson at CCG Consulting argues that the protestors do have an element of truth. Dawson addresses these health concerns around 5G and small cells on his blog, POTs and PANs. The first item of business that Dawson takes care of is explaining in clear terms what 5G even is. Then he dives into what the actual health effects are and how concerned we should be.

5G Basics

5G is confusing because it actually refers to three types of technologies: mobile cellular, gigabit radio, or high-speed wireless connections. Protestors have conflated these types of 5G together. Dawson explains the differences among these technologies and whether there are actual health risks to any of them. He also notes that 5G is not going to be here any time soon:

"It might be a decade until we see a full 5G cellular installation. There are 13 major specifications for improvements between 4G and 5G and those will get implemented over the next decade. This won’t stop the marketing departments of the cellular carriers to loudly claim 5G networks after one or two of these improvements have been partially implemented."

Health Concerns

Most of the 5G technologies should not pose a problem; the concern is with the particular technology that uses millimeter wave spectrum. Some research suggests that this can have ill effects on the environment. Other studies have shown few health effects, such as this article about millimeter wave spectrum and lab rats, but more research is needed. Dawson points out that most countries, including the U.S., have agreed to explore millimeter wave spectrum deployment except for Belgium, which has banned it until there is more research on the health effects. He describes the potential problem here:

This is the transcript for Community Broadband Bits Episode 262. Harold Feld and Christopher Mitchell discuss Microsoft's announcement on TV White Spaces and what it means for rural areas. Listen to this episode here.

Harold Feld: It's the openest public airwaves, because we actually let the public use it.

Lisa Gonzalez: This is Episode 262 of the Community Broadband Bits podcast from the Institute for Local Self-Reliance. I'm Lisa Gonzalez. TV White Spaces and White Space Technology has been in the news lately. Microsoft recently announced a plan to use White Spaces to bring high-speed internet access to rural areas across the country. This week, Harold Feld, from Public Knowledge, takes some time to talk with Christopher about the announcement and White Space Spectrum. Microsoft has raised a stir with their proposal, and Harold explains why. Before we start the interview, we want to remind you that this is a commercial-free podcast, but it isn't free to produce. Please take a minute to contribute at ILSR.org. If you're already a contributor, thank you for playing a part in keeping our podcast going. Now, here's Christopher with Harold Feld from Public Knowledge.

Christopher Mitchell: Welcome to another edition of the Community Broadband Bits podcast. I'm Chris Mitchell with the Institute for Local Self-Reliance, and I'm talking today with Harold Feld, the senior vice president for Public Knowledge. Welcome back to the show, Harold.

Harold Feld: Thank you.

Christopher Mitchell: One of the things that you've been working on for a very long time is something called TV White Spaces. Why don't you tell us a little bit about what they are?

San Jose State University’s School of Information (iSchool) and the Gigabit Libraries Network are accepting proposals for projects under a National Leadership Grant from the Institute of Museum and Library Services (IMLS) to expand the Libraries WhiteSpace Project. According to the announcement, five projects will be funded.

The “Beyond the Walls” Awards will provide $15,000 grants “to libraries for the most innovative proposals to use TV WhiteSpace (TVWS) technologies to enable new library hotspots in the service of their communities.”

Co-director Kristen Reman of SJSU said:

"This initiative will further explore the role of libraries as leading community anchors promoting access and inclusion through strategic technology integration. There's a nice intersection between what we're implementing and the concept of community anchors, which has been used by IMLS to describe the role of libraries in providing civic engagement, cultural opportunities, and economic vitality to communities,"

The first round of applications will be accepted until March 6th winners will be announced near the end of April. Libraries interested in applying for an award can watch a quick 2-minute video to help them determine if they meet qualification criteria. You can also contact info(at)giglibraries.net with questions; they will even help you put together a project plan.

White Space Technology

"White spaces" or "TVWS" are the unlicensed low-frequency spectrum that was reserved for television signals prior to digitization of television. Now that the spectrum is not being used for TV, it's been freed up for fixed wireless Internet accesss.

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.

You can view the full text of the PISC comment through the link below.

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.
