In this episode of the Community Broadband Bits podcast, we get an introduction to what this week's guest calls "the most Southern of protocols" Wi-Fi. Here to guide us is Heather "Mo" Williams, Manager of Solutions Engineering at Ruckus Networks, Wi-Fi engineer for Black Hat conferences, and co-host on the podcast This Week in Enterprise Tech.

During her conversation with Christopher, Mo shares her background with Ruckus Networks and her family's personal experience with poor connectivity in rural Texas. Then, Mo and Christopher discuss the history of Wi-Fi, the basics of how it functions, and what it means to operate over unlicensed spectrum. Mo explains how network congestion and the proliferation of Wi-Fi-enabled devices challenge engineers.

Christopher and Mo talk about the overblown hype around 5G technologies. They also dig into the Federal Communications Commission's wireless policies, and Mo commends the agency for it's recent decision to open up more spectrum for Wi-Fi, calling it a "game changer."

This week on the Community Broadband Bits podcast, Christopher speaks with Steve Song, a fellow at Mozilla who works to connect unserved communities across the globe.

Steve shares his background starting out at a nonprofit Internet service provider in 1990s South Africa, and they discuss the negative but mostly positive effects of widespread Internet access. While acknowledging the limitations of mobile connectivity, Steve describes the essential role wireless technologies have played in connecting people worldwide. To get everyone online, Steve argues that we need a mixture of models, including wireless providers.

Christopher and Steve also talk about how the potential impact of 5G is being diluted by focusing on high speeds instead of affordable, rural Internet access. At the same time, Steve explains that the U.S. has been a global leader in terms of opening up wireless spectrum for many uses. For better rural connectivity, Steve points to cooperatives as an exemplary model to follow, and he speaks to the need to treat spectrum differently in rural areas.

On February 3rd, 2020, the FCC opened the 2.5 GHz Rural Tribal Priority Window, a six month period in which federally recognized Tribes or Alaska Native Villages have the opportunity to apply for licenses to unassigned spectrum over their Tribal lands. This week on the podcast, we have two guests from MuralNet — CEO Mariel Triggs and Edyael Casaperalta, Legal Advisor and Policy Strategist. MuralNet, a nonprofit that focuses on helping indigenous people build their own networks, has been working to spread the word about the Rural Tribal Priority Window.

Historically, national Internet access companies have fallen short in bringing their services to people living on tribal lands. A few Tribes have been able to develop their own community networks, but others have found roadblocks when competing with large ISPs for spectrum or for funding. As a result, Tribal communities are some of the least connected in the U.S. Mariel and Edyael discuss how fixed wireless, using the 2.5 Ghz band spectrum is well suited to help solve this persistent problem. They share some of the challenges they’ve faced and offer some tips with deployment and in working to develop policy.

We learn more about the criteria that tribes need to meet in order to apply and how, even if they don’t plan on building their own network, owning access to the spectrum is, nevertheless, empowering. Tribes may not wish to operate a community network, but owning the airwaves above their land gives them some control over how those airwaves are used.

To learn more about the claiming the airwaves over Tribal Land, check out MuralNet’s website here. They're always willing to answer questions and to help with the process.

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. 

orangewireless_2.jpg In the spring of 2018, the tribe obtained a temporary Educational Broadband Service (EBS) Spectrum license. MuralNet, local ISP Niles Radio, and Northern Arizona University have all contributed toward the effort to launch the community network. Niles Radio provided 30 Megabits per second (Mbps) backhaul at no charge in addition to volunteering to help with deployment. With MuralNet professionals and volunteers from the community, the LTE network was up and running within a day. Equipment costs for what MuralNet describes as the first phase of the network were $15,000. As a result, a few...

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:

"A deployment of millimeter wave loops means constantly bombarding residential neighborhoods with millimeter wave spectrum from poles on the curb. The other planned use of millimeter wave spectrum is for indoor routers that will transmit gigabit bandwidth inside of a room. People can clearly decide to not use millimeter wave...

Matt Rantanen, director of technology at the Southern California Tribal Chairmen’s Association and director of the Tribal Digital Village Network, has been working for years to get tribal communities connected to broadband. In his conversation with Christopher, he talks about his experience with creative wireless solutions, the potential of the Educational Broadband Service (EBS) to get folks connected, and shifting attitudes around the importance of broadband.

“We’re trying to help solve that rural connectivity problem. America’s got a lot of talented people that live outside the city centers, and they just don’t have access to the resources that they need — and a lot of those people are on reservations. So it’s really important to get those people connected.”

Matt’s newest venture, Arcadian InfraCom, is creating new, diverse fiber paths thanks to innovative partnerships with tribal communities. Phase 1 of their plan, scheduled to be completed in 2022, will connect Salt Lake City to Phoenix and Phoenix to Denver, with add/drop locations within the Navajo Nation and throughout Utah, Colorado, and Arizona.

We talked to Matt previously on Community Broadband Bits episode 76 and on an episode of our Community Connections series. Check out our other stories on tribal lands connectivity 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?

Harold Feld: Yeah, so this is always very confusing, because like a lot of things, the name doesn't actually make any sense if you're not immersed in this. In wireless spectrum talk, white spaces are frequency bands that haven't been assigned to anyone, because they appear -- Usually, if you have a chart of how spectrum is allocated, who's doing what in which frequency bands. Something that has not been assigned to anybody appears in white, so engineers call that a white space. So, television needs a lot of these because...

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.

We’ve covered how libraries are using white space technology to expand free Internet access in local communities. Garrett County, Maryland, plans to use TVWS to complement its fiber network and bring connectivity to some areas of the county were traditional fixed wireless can't serve....

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:

"Today's bipartisan FCC vote to create a Citizens Broadband Service is a historic...
