The three-year project is part of NSF\u0026rsquo;s Smart and Connected Communities initiative.\u003C\/p\u003E\r\n\r\n\u003Cp\u003ESchool of Computer Science Professor \u003Ca href=\u0022https:\/\/www.cc.gatech.edu\/fac\/Ellen.Zegura\/Welcome.html\u0022\u003E\u003Cstrong\u003EEllen Zegura\u003C\/strong\u003E\u003C\/a\u003E is co-principal investigator along with University of California Santa Barbara Professor \u003Cstrong\u003EElizabeth Belding\u003C\/strong\u003E, Arizona State University Professor \u003Cstrong\u003EMarisa Duarte\u003C\/strong\u003E, and Northern Arizona University Assistant Professor \u003Cstrong\u003EMorgan Vigil-Hayes\u003C\/strong\u003E.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EThe disconnect\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003EWhile the rest of the country continues moving toward optical fiber and 5G connectivity in 2019, tribal lands can be a networking dead zone. Network research often operates under the assumption that a region has some pre-existing network, whether it\u0026rsquo;s an internet service provider or cellular data. Then researchers build a stronger network off of what is already available. Yet many tribal lands have no coverage because of difficult geography and low population density, creating little economic incentive for traditional providers to offer an affordable option.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;This lack of connectivity does exist in other parts of the U.S., but it\u0026rsquo;s especially acute in Native American lands,\u0026rdquo; Zegura said.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn 2018, the Federal Communications Commission (FCC) released a report stating that 1.2 million Native Americans don\u0026rsquo;t have mobile broadband connectivity. Worse yet, a later Government Accountability Office report countered saying the FCC overestimated their coverage. This is because the FCC considers an area to be broadband accessible even if just one house has connectivity.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThis lack of network connectivity is detrimental to the health of Native American communities, who rely on the internet for online commerce, improving education, and tribal communications.\u003C\/p\u003E\r\n\r\n\u003Cp\u003ENetworking researchers have been aware of the problem for years. Zegura and Belding have been working with collaborators on creating stronger networks for tribal lands since 2016 when NSF awarded $700,000 for a project called TribalNet that included Penn State, Georgia Tech, and UCSB. That project supported connectivity on Southern Californian tribal lands by expanding unused television broadcasting frequencies.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003ECreating a network\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003EWith the new NSF funding, the team will work to expand network access for Native American communities in Northern New Mexico. While the prior research focused on supporting downloadable content with underused networks, the new initiative emphasizes a network that can support new content creation and interaction where one doesn\u0026rsquo;t already exist.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe group is using LoRa to help create this network. Its long transmission range makes it low cost enough to cover an entire area, even if that area has no pre-existing network. Devices can start as low as $15 and need very little maintenance, making them ideal for low-income areas.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EYet the way the researchers are using LoRa is also novel. Traditionally networks operate with two planes over the same network infrastructure: the data plane and control plane. The data plane carries user traffic and is what enables information to be downloaded. The control plane carries signal traffic and routing information for networks. The researchers will be decoupling the two planes and using LoRa for control traffic to optimize use of traditional networks.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EWorking with a community\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003EOne of the other goals of the project is to ensure the community gets value from the work.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;There\u0026rsquo;s a long history of researchers doing research in communities but not leaving behind anything of long-lasting value,\u0026rdquo; Zegura said.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EHowever, this project will be building networks on-site and offering technical training short courses for community members.
