The federal government has recognized 573 Indian tribes as distinct, independent political communities with certain powers of sovereignty and self-government, including some power to manage the use of their territory and resources and control economic activity within their jurisdiction. Some tribal lands include reservations—land set aside by treaty or other agreement with the United States, executive order, or federal statute or administrative action for the residence or use of an Indian tribe. Some tribal lands include parcels with different ownership; for example, parcels may be held in trust by the federal government for the benefit of a tribe or an individual tribal citizen. Trust and restricted lands can affect a tribe’s ability to use their land as collateral to obtain a loan. Tribal lands vary in size, demographics, and location. For example, the smallest in size are less than one square mile, and the largest, the Navajo Nation, is more than 24,000 square miles (the size of West Virginia). Tribal land locations can range from extremely remote, rural locations to urban areas. Indian tribes may form governments and subsidiaries to help manage tribal affairs including schools, housing, health, and economic enterprises. Internet access in the United States is generally privately financed. Broadband providers build infrastructure and sell broadband services to individual consumers. We previously reported that tribal lands can have conditions that increase the cost of broadband deployment, such as remote areas with challenging terrain, which increases construction costs, as well as relatively low population densities and incomes that make it difficult to recoup deployment costs. These conditions may make it less likely that a service provider will build or maintain a network. Some tribal governments provide Internet access to their members, through an information-technology or utility department, and others have created their own telecommunications companies to provide services. FCC has reported that in many instances, tribal governments must build and pay for their own communications infrastructure to ensure Internet access will be “delivered across Indian Country.” The term “broadband” commonly refers to Internet access that is high speed and provides an “always-on” connection, so users do not have to reestablish a connection each time they access the Internet. Telecommunications providers use a range of technologies to provide broadband service, including cable, fiber, satellite, and wireless. Wireless broadband connects users to the Internet using spectrum to transmit data between the customer’s location and the service provider’s facility, and can be transmitted using fixed wireless and mobile technologies, as shown in figure 1. Fixed wireless broadband technologies establish an Internet connection between fixed points, such as from a radio or antenna that may be mounted on a tower, to a stationary wireless device located at a home. This technology generally requires a direct line of sight, and can be delivered two ways: (1) as a point-to-point transmission—between two fixed points—or (2) as a point-to-multipoint transmission—from one point to multiple users. Mobile wireless broadband technologies also establish a connection to the Internet that requires the installation of antennas, but this technology provides connectivity to customers wherever they are covered by service, including while on the move, such as with a cell phone. Spectrum is the resource that makes wireless broadband connections possible. Spectrum frequency bands each have different characteristics that result in different levels of ability to cover distances, penetrate physical objects, and carry large amounts of information. For example, lower frequency bands are able to transmit signals that travel greater distances, thus requiring the use of fewer antennas, and are able to penetrate solid objects. Higher frequency bands are able to transmit more data, but are more easily obstructed. FCC administers spectrum for nonfederal users—such as state, local government, and commercial entities—through a system of frequency allocation and assignment. Allocation involves segmenting the radio spectrum into bands of frequencies designated for use by particular types of radio services or classes of users, such as commercial and nonfederal broadband services. Examples of some of the frequency bands that can be used by commercial and nonfederal entities for broadband services are shown in figure 2. Appendix II presents a full list of the auctioned licensed frequency bands that FCC told us could be used to provide broadband services. The frequency bands that can be used for broadband services are either licensed or unlicensed. For licensed spectrum, FCC can assign licenses through auctions, in which prospective users bid for the exclusive rights to transmit on a specific frequency band within geographic areas, ensuring that interference does not occur. License holders may sell or lease their license, in whole or in part, to another provider, a process that is known as a secondary market transaction, with FCC’s approval. FCC requires license holders to meet specified buildout requirements within a specified amount of time or face penalties, typically termination of all or part of the license. These buildout requirements are designed to ensure that licensees put spectrum to use within a specific period rather than let it sit idle and vary based on the type of license. FCC has also assigned licenses administratively in two frequency bands that can be used for broadband services. Specifically, prior to 1996 FCC assigned geographic licenses for exclusive use in the Educational Broadband Service (2496-2690 megahertz (MHz)), and from 2005 to 2015, FCC assigned non-exclusive nationwide licenses in the 3650-3700 MHz band, where use of the band may be shared by other license holders. FCC also authorizes the use of some spectrum for broadband services without a license on a non-exclusive basis. With unlicensed spectrum, an unlimited number of users can share frequencies using wireless equipment certified by FCC, such as wireless microphones, baby monitors, and garage door openers. In contrast to users of licensed spectrum, unlicensed users have no regulatory protection from interference by other licensed or unlicensed users in the bands. If multiple users are operating simultaneously on the same frequency band, the transmissions may be susceptible to interference, which reduces the quality of service. FCC’s rulemaking process includes multiple steps as outlined by law with opportunities for the public to participate during each step. In general, FCC initiates a rulemaking in response to statutes, petitions for rulemaking, or its own initiative, and releases a Notice of Proposed Rulemaking (NPRM) to propose new rules or to change existing rules. Any interested person may submit comments as part of the public record through electronic filings and meetings with FCC officials. Following internal analysis of the public record, FCC staff may propose actions for consideration for a vote, such as adopting final rules, amending existing rules, or stating that there will be no changes. All of FCC’s sitting commissioners vote on these items. The American Recovery and Reinvestment Act of 2009 directed FCC to develop a plan to ensure every American had access to high-speed Internet. In March 2010, an FCC task force issued the National Broadband Plan that included a centralized vision for achieving affordability and maximizing use of high-speed Internet. The plan made many recommendations to FCC, including that FCC should take into account the unique spectrum needs of tribal communities when implementing spectrum policies and evaluate its policies and rules to address obstacles to spectrum access by tribal communities. With regard to tribal lands, the plan recommended that FCC increase its commitment to government-to-government consultation with tribal leaders and consider increasing tribal representation in telecommunications planning. FCC established the Office of Native Affairs and Policy (ONAP) in July 2010 to promote the deployment and adoption of communication services and technologies to all native communities, by, among other things, ensuring consultation with tribal governments pursuant to FCC policy. Through our analysis of FCC license data as of September 2018, we identified 18 tribal entities that held active spectrum licenses in bands that can be used to provide broadband services. Because tribal entities may hold licenses using entity names that do not include the search terms we identified in our review of the list of tribes in the Federal Register, there may be additional tribal entities that we have not identified. We found that most of the tribal entities obtained the licenses through FCC administrative assignment rather than through an FCC spectrum auction or secondary market transaction. Thirteen of the tribal entities we identified in FCC’s license data held administratively assigned licenses, and these licenses are subject to certain limitations and were only available to applicants for limited time periods. Eleven of these administratively assigned licenses are non- exclusive nationwide licenses in the 3.65 GHz frequency band (3550- 3700 MHz) and were available between 2005 and 2015, when FCC issued a new rule for this band and stopped accepting new applications for these licenses. Two of the tribal entities we identified held administratively assigned Educational Broadband Service licenses in the 2.5 GHz frequency band (2496-2690 MHz). These licenses allow for the transmission of educational materials by accredited educational institutions and government organizations, including tribes, engaged in formal education and require that licensees use the spectrum for educational purposes for a certain amount of time each week. Both of these tribal entities obtained these licenses after the last filing window closed in 1996 through a waiver and special temporary authority permit. Four tribal entities we identified in FCC’s license data held a total of 13 active licenses obtained through secondary market transactions, such as leases and sales of portions of partitioned licenses. Of these 13 secondary market transactions, 2 involved nationwide providers. Two of the tribal entities we identified held active licenses in bands available for broadband deployment that they obtained through an FCC spectrum auction. One of these tribal entities won with a winning bid of over $800,000 in a 2015 auction, and the other won two licenses with winning bids of under $50,000 in a 2002 auction. This second tribal entity also qualified for but did not win a 2003 auction. In addition to these two tribal entities, we identified the following four tribal entities that had applied to participate in auctions with varying results but did not hold active licenses in frequency bands available for broadband deployment as of September 2018: Two tribal entities each won a single spectrum license. The first won its license, which has since expired, in 2000, and the second won its license, which it has since been transferred to a nationwide provider through a secondary market transaction, in 2003. The first tribal entity also applied but did not qualify to participate in a 2001 auction. One tribal entity qualified to participate but did not win in a 2003 auction, and another tribal entity applied but did not qualify to participate in a 2008 auction. In addition, representatives from 2 of the 16 tribal entities we interviewed that were using wireless technologies told us that they use licensed spectrum that is owned by a private provider through a partnership relationship. We have previously reported that some tribes have formed partnership arrangements with other entities to increase broadband access on tribal lands. Most (14 of 16) of the tribal entities we contacted that were using wireless technologies told us that they are accessing various unlicensed bands, such as the 2.4 GHz and 5 GHz bands, to provide service. Representatives from eight of these tribal entities reported using only unlicensed spectrum for their fixed wireless networks. Representatives from 13 tribal entities told us that unlicensed spectrum had the advantage of being free, and representatives from one tribal entity told us that the equipment needed to access these spectrum bands is less expensive than equipment for accessing other spectrum bands. Representatives from some tribal entities reported success in using unlicensed spectrum in certain circumstances. For example, one tribal entity reported using unlicensed spectrum for homes in remote areas where the only potential signal degradation is from trees as well as to set up local hot spots that can serve 5 to 10 users at a time. Another tribal entity reported using primarily unlicensed spectrum to carry signals to end users together with non-exclusive licensed spectrum (3.65 GHz band) for locations where there is congestion in the unlicensed bands. However, representatives from the tribal entities we contacted that were using wireless technologies emphasized the advantages of licensed spectrum and discussed their experiences with the limitations of unlicensed spectrum. As described earlier, exclusive-use spectrum licenses protect license holders from interference from other users, whereas unlicensed spectrum provides no protection against interference. Representatives from 13 of 16 tribal entities identified the fact that unlicensed spectrum is available at no cost as an advantage of this type of spectrum. However, representatives from 15 of the 16 tribal entities identified limitations associated with unlicensed spectrum, such as interference, as described in table 1. Tribal associations, an academic group, a tribal consortium, and FCC have all highlighted the importance of exclusive-use licensed spectrum for tribal entities. Specifically, both a tribal association and an academic group we contacted discussed interference and other challenges of unlicensed spectrum. Representatives from one tribal association pointed out that unlicensed spectrum might not be available in the future if it is allocated for other purposes. Representatives from a tribal consortium we contacted told us that they are already using all of the available unlicensed spectrum for providing Internet access and that they cannot expand service without encountering interference and capacity limitations. Lastly, ONAP reported in 2012 that unlicensed spectrum is not an option across all tribal lands and that tribal access to robust licensed spectrum is a critical need. Representatives from the stakeholders we interviewed told us that there are also non-technological benefits for tribal entities to obtain greater access to licensed spectrum. For example: Enhanced ability to deliver additional Internet service. Representatives from one of the tribal associations, an academic group, and six of the tribal entities said that increased access to licensed spectrum would enable them to deliver their own Internet services and bridge service gaps, thus improving Internet access to their members. For example, representatives from three of these tribal entities said that such access would enable them to deploy in areas where providers that currently hold licenses were not willing to deliver services. In addition, representatives from another tribal entity said that having access to licensed spectrum is one factor that would enable the tribe to establish its own telecommunications company. Ability to sell or lease spectrum for profit. Representatives from one tribal association, an academic group, and two tribal entities told us that holding spectrum licenses would enable tribal governments to sell or lease their licenses. For example, we heard from one of these tribal entities that it was able to sell portions of its license that did not cover tribal lands and to use the profits from the sale to invest in its own network infrastructure. Opportunities for federal funding. Access to licensed spectrum may also provide tribal entities with more opportunity to obtain federal funding, specifically through two Universal Service Fund programs— the Mobility Fund and the Tribal Mobility Fund. These programs provide funding to broadband service providers to expand service in areas where it is not available, including tribal lands. However, service providers must hold, lease, or show they have access to licensed spectrum to participate in these programs, among other requirements. For example, the National Congress of American Indians stated that two tribal entities submitted applications to participate in the Mobility Fund program but were not eligible to participate in part because they did not hold a spectrum license. Moreover, representatives from two of the tribal entities we interviewed told us that they considered applying for one of these programs but realized they were ineligible because they did not have access to licensed spectrum. Furthermore, representatives from one of the tribal associations, an academic group, and seven of the tribal entities told us that having access to licensed spectrum would enable tribes to exercise their rights to sovereignty and self-determination. Representatives from three of the tribal entities we contacted said that they view spectrum as a natural resource that should be managed by the tribe. FCC officials, however, told us that spectrum is not considered a reserved right under treaties with Indian tribes, as it is not explicitly stated. In addition, representatives from four of the tribal entities told us that having access to licensed spectrum would ensure that spectrum is being used in a way that aligns with tribal goals and community needs, further supporting their rights to self-determination. Representatives from the tribal entities we contacted identified several barriers to accessing licensed spectrum through spectrum auctions and secondary market transactions. Regarding spectrum auctions, representatives from tribal entities that provide wireless Internet service most frequently (13 of 16) indicated that spectrum licenses are too expensive for tribal entities. For example, over 60 percent (983 of 1,611) of the winning bids from a 2015 spectrum auction, including bids for spectrum over non-tribal lands, were over $1 million. Representatives from one tribal entity explained that auction licenses are often too expensive for tribal entities because these licenses cover large geographic areas that may include non-tribal urban areas as well as rural tribal areas. Moreover, representatives from eight tribal entities stated that they are unable to obtain financing to participate in auctions because tribal governments cannot use tribal lands as collateral to obtain loans. In addition, representatives from eight tribal entities mentioned that participating in spectrum auctions requires auction-specific expertise that tribal entities may not have. Tribal entities also face barriers obtaining spectrum through secondary market transactions. Most of the spectrum allocated for commercial use has already been assigned through spectrum auctions and other mechanisms to private providers, including licensees that may not be providing service on tribal lands. In a single geographic area, several frequency bands could be used to deploy broadband services, as shown in figure 2, and licenses for these various frequency bands may be held by different providers. There may be tribal areas where providers hold licenses for bands but are not using the spectrum to provide Internet access. In other tribal areas, services may be offered using one or two of the spectrum licenses with the other licenses in the area remaining fallow and inaccessible to tribal entities. All three of the tribal associations we contacted confirmed that there are unused spectrum licenses over tribal lands, and representatives from a nationwide provider indicated that they only deploy services if there is a business case to support doing so. Accordingly, the secondary market is one of few avenues available to tribal entities that would like to access licensed spectrum. However, representatives from tribal entities we contacted identified the following challenges related to participating in the secondary market: Lack of willing sellers. Representatives from eight of the tribal entities, one of the tribal representative groups, and an industry association we contacted indicated that spectrum license holders are often unwilling to participate in secondary market transactions, citing a variety of reasons. For example, representatives from one tribal entity stated that large carriers have no business incentive to negotiate secondary market agreements with tribal entities and that tribal entities do not have the resources to make such transactions sufficiently lucrative for license holders. Representatives from another tribal entity stated that license holders may lack knowledge about the areas covered by their licenses, including tribal areas, and therefore may be unwilling to consider secondary market transactions. Representatives from a tribal representative group told us that license holders may be unwilling to consider secondary market transactions with tribal entities because spectrum is a valuable resource that may become even more valuable over time, and a representative from an industry association indicated that transaction costs such as legal fees outweigh any potential income from such transactions. None of the private providers we contacted reported entering into a secondary market transaction with tribal entities, but one of these providers stated that it had never been approached by a tribal entity interested in a secondary market transaction and was unaware of challenges that are unique to tribal entities. License holders unknown. Representatives from eight of the tribal entities we contacted stated that it is difficult to determine who holds spectrum licenses. For example, two tribal entities had to hire consultants to identify who held licenses for spectrum over the tribes’ lands, and another tribal entity relied on the expertise of its non-tribal partner to identify the license holders. Unaware of secondary market transactions. Representatives from six of the tribal entities we contacted were unaware of the possibility of accessing licensed spectrum through a secondary market transaction prior to our contacting them. Accordingly, secondary market transactions involving tribal entities are rare. As discussed above, our analysis of FCC license data identified four tribal entities that have successfully accessed licensed spectrum in this manner. Regarding one of these tribal entities’ experiences with the secondary market, the tribal representative we contacted stated that an Indian-owned telecommunications consulting company was pivotal in identifying the license holder and facilitating the transaction and that the transaction would not have happened without the consulting company. Representatives from this company told us that they conducted an analysis to identify unused spectrum licenses over the tribe’s land. The company identified three providers holding such licenses, but only one of those providers was willing to participate in a secondary market transaction. Representatives from another of the tribal entities that accessed licensed spectrum through the secondary market told us that they relied on the expertise of their non-tribal partner to facilitate these transactions. We found that FCC has taken the following actions to increase tribal access to and use of spectrum: (1) initiated proposed rulemakings on promoting tribal access to spectrum, (2) adopted rules to increase spectrum available for broadband use, and (3) conducted outreach and training for tribal entities on spectrum-related issues. FCC issued two NPRMs—one in March 2011 and one in May 2018—that included policy options intended to enhance tribal access to spectrum. At the time of our report, FCC had not adopted new rules or taken further action on the 2011 rulemaking, and FCC had not taken further actions since the comments period ended on September 7, 2018, on the May 2018 rulemaking. According to FCC officials, the 2011 NPRM addressed several recommendations made in the National Broadband Plan to promote the greater use of spectrum over tribal lands. Among other things, the 2011 NPRM sought comments on three proposals to create new spectrum access opportunities for tribal entities (see fig. 3). FCC officials told us that they have reviewed public comments to the proposed rulemaking, but have no current plans to take further actions. We reviewed the public comments FCC received that pertained to the three proposals, which included comments from tribal associations, tribal governments, rural and nationwide industry associations, and tribal and private providers. Based on our analysis of the comments that included positions on the proposal for a tribal licensing priority, eight stakeholders—including industry associations, private providers, and a tribal government—were supportive of this proposal. However, we found that stakeholder views differed on implementing good faith negotiations and on the build-or-divest processes. In general, the tribal stakeholders indicated that they were supportive of these proposals, while the industry associations and private providers were not. In addition to reviewing the public comments, we asked representatives from the tribal and industry associations and private providers that we interviewed about their views of these proposals. Representatives from the three tribal associations and two rural industry associations were generally supportive of all three of the proposals, while representatives from one of the private providers that we interviewed told us they did not support any of the three proposals, because, for example, they said that there are more effective ways to increase broadband service over tribal lands. Representatives from another private provider said that they supported the tribal priority process but did not indicate their views on the other two proposals. Representatives from six tribal entities and a representative from a tribal consortium told us that these types of proposals would help them obtain spectrum. In May 2018, FCC issued an NPRM that sought comments on establishing a tribal priority window for tribal nations located in rural areas as part of a process to re-license the Educational Broadband Service spectrum band. As described above, FCC originally allocated this band to qualifying educational institutions and government organizations for the transmission of educational materials. While FCC permitted licensees to lease their excess capacity to commercial providers, FCC reported that significant portions of this band were not being used, primarily in rural areas. In an effort to make additional spectrum available for broadband use, FCC issued this NPRM seeking comments on options to promote the use of this spectrum over tribal lands. One of the options included implementing a local priority filing window so that tribal entities could get access to unassigned spectrum prior to an FCC auction. In a June 2018 order, FCC extended the comment deadline for the NPRM to August 8, 2018, partly in response to a request for a deadline extension. As a result, FCC also extended the deadline to respond to those comments to September 7, 2018. Because FCC was in the process of responding to these comments at the time of our review, we did not analyze these comments. FCC has made additional unlicensed and licensed spectrum available for broadband use and has implemented rules that according to FCC, may make it easier for rural providers to obtain licenses. However, these efforts were not targeted to tribal entities, and according to ONAP’s 2012 report, allocating additional unlicensed spectrum may not be a technically feasible solution for all tribal entities, and such spectrum may not have the necessary capacity to handle an increase in users. In addition, representatives from the tribal associations and entities we contacted told us that there are limitations to the extent that these efforts can address the spectrum needs of tribal entities. In particular, they discussed the effect of FCC’s changes to the rules on the use of TV white space spectrum and the Citizens Broadband Radio Service spectrum: TV white space spectrum: In 2010, FCC made additional unlicensed spectrum available for broadband use by allowing providers to operate in the TV bands at locations where those frequencies were not in use, known as TV white space, but none of the tribal entities we interviewed was using this spectrum. A representative from a tribal consortium said that it used TV white space spectrum, and representatives from three of the tribal entities said that they were considering using it in the future because TV white space spectrum can better pass through some environmental barriers, such as trees, reaching more remote customers. However, representatives from five tribal entities, one tribal consortium, one academic group, and three companies that we interviewed told us about several limitations to the use of TV white space spectrum. For example: limited bandwidth capacity, which causes lower speeds, high latency, and limits the number of households that can be served; equipment needed to access TV whitespace spectrum is expensive and less available; the spectrum may not always be available; and similar to other unlicensed frequency bands, as described above, there is potential for interference and difficulty to pass through extreme terrain. Citizens Broadband Radio Service (CBRS) Spectrum: In 2015, FCC made additional licensed spectrum available for broadband use when it issued a new rule for the 3.65 GHz frequency band (3550-3700 MHz). However the tribal entities who held licenses in this band indicated there are limitations to their ability to use this band and their future use of this spectrum remains unknown. As described earlier, FCC had allocated non-exclusive nationwide licenses in this band. In the 2015 rule, FCC created the CBRS, increased the amount of spectrum allocated for commercial broadband use, and implemented a new licensing scheme. This three-tier priority licensing scheme for spectrum sharing included auctioning exclusive-use geographic licenses and allowing non-exclusive use of the band where a license holder is not operating, an approach that is intended to provide a low- cost entry point for users, but will have no protections from interference. Representatives from four of the five tribal entities that we contacted that held licenses in this band said that there were technical advantages to using it, such as the ability for a signal to pass through dense forests. However, representatives from two tribal entities said that the high cost of the equipment needed to access this spectrum prevented them from either using the frequency band extensively or at all. In addition, representatives from two tribal entities said that they were not sure about their ability to access this band in the future given the changes made in FCC’s 2015 rulemaking. FCC’s 2015 rule also created small-sized and shorter-termed licenses, which FCC stated would decrease the costs of obtaining a license and help rural providers access it. However, FCC issued an NPRM in 2017 that sought comments on suggested changes to CBRS, including increasing the geographic area covered by licenses and lengthening the license term. In October 2018, FCC adopted rules that, among other changes, increased the license area from census tracks to counties and extended the license term from 3 to 10 years, which FCC officials told us were modest changes made to accomplish FCC’s goals of creating incentives for investment, including in urban and rural areas, encouraging efficient spectrum use, and promoting robust network deployments. FCC’s ONAP conducts training, consultation, and outreach to tribal entities on spectrum-related issues. For example, ONAP officials told us that they have conducted 21 training and consultation workshops for tribal entities on broadband and telecom since 2012, where spectrum has been discussed in general in the introduction and has been addressed specifically in separate sessions in some of the workshops. These officials also told us that they communicate with tribal entities prior to when FCC holds auctions or when implementing regulatory actions or policies that will affect tribal governments and spectrum over their lands. While representatives from 9 of the 16 tribal entities using wireless technologies told us that they had received some outreach on spectrum- related issues from FCC, representatives from 2 of these entities said that they had not. In addition, ONAP issued a report in 2012 to provide FCC with a review of its work with tribal governments and organizations, including information on its tribal broadband efforts, priorities, and tribal consultations. Among other things, the report included case-study information on tribal entities’ efforts to access spectrum. Although the report stated that this would be the first of such annual reporting, this is the only report that ONAP has issued on tribal issues. According to ONAP officials, ONAP has not published subsequent reports because it provides FCC with information on its work with tribal governments and organizations, including spectrum-related matters, through more frequent informal briefings and regular updates. FCC has not consistently collected information related to tribal access to spectrum. For example, FCC does not collect data on whether holders of spectrum licenses or auction applicants are tribal entities even though it collects self-reported data on licensee type, such as corporation and government entity. To obtain this information, FCC could include an option for the licensee type, along with the other options, in applications for future licenses and auctions that allows an applicant to identify as a tribal government or tribally owned entity. FCC officials told us that they use information on licensee type to determine eligibility for a license. Because eligibility is not based on whether the applicant is a tribal entity, FCC officials said this information is not needed. However, without this information, FCC does not have a comprehensive understanding of the extent that tribal entities are attempting to obtain or access licensed spectrum or have been successful at obtaining and accessing it. Additionally, FCC does not analyze information on unused licensed spectrum that exists over tribal lands, even though FCC has information—broadband availability data from providers and information on geographic areas covered by spectrum licenses—that could be used for such analysis. As we described earlier, representatives from all three of the tribal associations we contacted reported that there are unused spectrum licenses over tribal lands that could present opportunities through the secondary market for tribal entities to obtain spectrum. When we asked FCC officials why they do not analyze the extent that unused spectrum licenses exists over tribal lands, they told us that the spectrum data noted above is not specific enough to allow for a license by license analysis of unused spectrum. For example, they said that broadband availability data from providers is aggregated across wide spectrum bands to minimize reporting burdens on the wireless industry, and the data are not sufficiently detailed to identify which spectrum blocks and licenses are being used in particular areas. However, FCC could use this data to conduct, at a minimum, high-level analysis that would result in useful information on the extent to which unused spectrum exists over tribal lands. In addition, FCC officials told us that they evaluate the effectiveness of FCC’s secondary markets policies, which FCC views as a mechanism to promote the increased use of unused spectrum licenses, but this approach does not include an analysis of unused spectrum licenses as part of these efforts. As a result, FCC’s evaluations of the secondary market may not accurately reflect how these policies affect tribal access to spectrum. Because the secondary market is one of few ways for tribal entities to access licensed spectrum, an analysis of unused licensed spectrum that exists over tribal lands would enable FCC to better promote a robust secondary market that provides additional opportunities for tribes to access spectrum. FCC’s 2010 National Broadband Plan stated that ongoing measurement of spectrum utilization should be developed to better understand how spectrum resources are being used because some studies indicated that spectrum goes unused in many places much of the time. The plan also stated that any spectrum utilization studies that FCC conducts should identify tribal lands as distinct entities. In FCC’s February 2018 strategic plan, FCC stated that it will implement ongoing initiatives that will assist in spectrum policy planning and decision making, promote a robust secondary market in spectrum, and improve communications services in all areas of the United States, including tribal areas. Additionally, Standards for Internal Control in the Federal Government state that agencies should use quality information, including information that is complete, to inform the decision-making processes. FCC also does not make information on spectrum-license holders available in an easy or accessible manner; such information could be beneficial to the tribes in their efforts to obtain spectrum in the secondary market. As described earlier, the secondary market is a significant mechanism for tribal entities to obtain spectrum licenses, but representatives from the tribal entities we interviewed reported challenges related to participating in the secondary market, such as not knowing whom to contact should they wish to engage in a secondary market transaction to obtain a spectrum license. In July 2014, FCC stopped updating its spectrum dashboard, which provided the public with a way to identify who holds licenses in what areas, including features that allowed users to identify spectrum allocated and assigned in tribal lands. ONAP stated in its 2012 report that this feature represented the first step for individual tribal entities to reach out to licensees and seek leasing, partnership, or other arrangements that could ultimately result in the provision of service over tribal lands. FCC officials told us that the public may view electronic records of all wireless spectrum licenses in FCC’s Universal Licensing System, using a wide range of license and geographic parameters, such as licensee names, radio services, spectrum bands, and geographic locations. However, we attempted to navigate the Universal Licensing System to determine spectrum-license holders for specific tribal lands using geographic parameters, but we were unable to successfully do so because the system is so difficult to use. Furthermore, as described above, representatives from eight of the tribal entities that we contacted stated that it is difficult to determine who holds spectrum licenses. When we asked FCC officials why they do not communicate information to tribes about spectrum-related transactions over tribal lands, FCC officials also told us that they issue public notices on applications for all proposed spectrum transactions and on the winning bidders of all auctions, but they have not made it a practice to reach out directly to tribes to make them aware of when providers have obtained spectrum licenses that cover tribal lands. The National Broadband Plan stated that FCC should make data available that would promote a robust secondary market for spectrum licenses, such as information on how and to whom spectrum is allocated on tribal lands. Additionally, Standards for Internal Control in the Federal Government state the need for federal agencies to communicate with external entities and to enable these entities to provide quality information to the agency that will help it achieve its objectives. Tribal governments are an example of such external entities. The ability of tribal governments to make informed spectrum planning decisions and to participate in secondary market transactions is diminished without information from FCC on the spectrum transactions that occur over tribal lands. Providing this information in a manner that is accessible and easy for tribal entities to obtain could enable them to enter into leasing, partnership, or other arrangements to obtain spectrum. Broadband service on tribal lands continues to lag behind the rest of the country, especially on rural tribal lands, which could hinder tribal efforts to promote self-governance, economic opportunity, education, public safety, and cultural preservation. FCC has reported that wireless technologies that access spectrum to deliver broadband services are cost-effective for remote and sparsely populated areas, such as tribal lands. However, FCC’s efforts to promote and support tribal entities’ access to spectrum have done little to increase tribal use of spectrum, as only very few tribes are accessing spectrum to be able to provide Internet service. Additionally, FCC lacks information that could help inform its decision- making processes related to spectrum policy planning, which is intended to improve communications services in all areas of the United States, including tribal lands. By collecting data on the extent that tribal entities are obtaining and accessing spectrum, FCC could better understand tribal spectrum issues and use this information as it implements ongoing spectrum initiatives. Furthermore, the secondary market is one of few ways for tribal entities to access licensed spectrum to be able to provide Internet service, and FCC has recognized the importance of promoting a robust secondary market. FCC could promote a more robust secondary market by analyzing data to better understand how much unused licensed spectrum exists over tribal lands and using that information to promulgate regulations and to evaluate how FCC policies affect tribal participation in the secondary market. Additionally, by making information on who holds spectrum licenses over tribal lands more accessible and easy to understand, FCC could remove a barrier tribes may face in attempting to obtain spectrum through the secondary market. We are making the following three recommendations to the Chairman of FCC. The Chairman of FCC should collect data on the extent that tribal entities are obtaining and accessing spectrum and use this information as FCC implements ongoing spectrum initiatives. (Recommendation 1) The Chairman of FCC should analyze data to better understand the extent that unused spectrum licenses exist over tribal lands, such as by analyzing the data for a sample of tribal lands, and as appropriate use this information to inform its oversight of the secondary market. (Recommendation 2) The Chairman of FCC should make information on spectrum-license holders more accessible and easy to understand for interested parties, including tribal entities, to promote their ability to purchase or lease spectrum licenses from other providers. (Recommendation 3) We provided a draft of this report to FCC for comment. In its comments, reproduced in appendix III, FCC agreed with the recommendations. FCC also provided technical comments, which we incorporated as appropriate. We are sending copies of this report to the appropriate congressional committees, the Chairman of FCC, and other interested parties. In addition, the report is available at no charge on the GAO website at http://www.gao.gov.

GAO staff who made key contributions to this report are listed in appendix IV. This report examines (1) what is known about the ability of tribal entities to obtain and access spectrum to provide broadband services on tribal lands and the reported barriers that may exist; and (2) the extent to which the Federal Communications Commission (FCC) promotes and supports tribal entities’ ability to obtain and access spectrum for broadband services. To address both objectives, we reviewed relevant statutes and regulations and FCC documents, including FCC’s Statement of Policy on Establishing a Government-to-Government Relationship with Indian Tribes, the National Broadband Plan, and FCC’s current strategic plan. We interviewed FCC officials and representatives from 3 tribal associations, 7 private providers that deliver Internet services over tribal lands, 3 industry associations that represent rural and urban telecommunications providers, 3 regional consortia, 3 companies that work with tribal entities, and 1 academic group. In addition, we selected 24 tribal entities—13 Indian tribes and nations and 11 tribally owned providers—to interview. To identify tribal entities that were using wireless technologies, we obtained recommendations from stakeholders, reviewed data on relevant federal grants, such as the Broadband Technology Opportunities Program, and conducted Internet research. We then selected 16 tribal entities considering (1) stakeholder suggestions, (2) population, (3) population density, and (4) urban or rural designation. We visited 7 of these tribes in Idaho, New Mexico, and Washington State. The views represented in our report are not generalizable to those of all stakeholders. See table 2 for a complete listing of the entities we interviewed. We also conducted a literature review to identify relevant academic, government, and media publications that were published between January 1, 2013, and January 11, 2018, that discuss the importance of and options to enhance tribal access to spectrum. To identify tribal entities that applied to participate in spectrum auctions or that held active spectrum licenses in bands that can be used to provide broadband service, we analyzed (1) FCC data on entities that applied to participate in auctions for spectrum in these bands and (2) FCC data on spectrum licenses in these bands that were active as of September 6, 2018. We also analyzed FCC license data, together with license information publicly available through FCC’s Universal Licensing System, to determine whether the tribal entities that held active licenses obtained those licenses through an FCC spectrum auction, administrative assignment, or the secondary market. We then reviewed the list of federally recognized tribes in the Federal Register and identified search terms related to these tribes. For example, we identified the following search terms based on the federally recognized tribe, Yurok Tribe of the Yurok Reservation, California, “Reservation, Tribe, and Yurok.” We then used the identified search terms to search for tribal entities in FCC’s data on auction participants and spectrum license holders. We manually reviewed these matches to identify tribal entities based on information from interviews, Internet research, and professional judgment. Because tribal entities may have applied to participate in spectrum auctions or may hold spectrum licenses under names not associated with their tribes, there may be additional tribal entities that we were unable to identify. Through interviews with FCC officials and review of related documentation, we determined that the license and auction participant data are sufficiently reliable for our purpose of identifying some tribal entities that have applied to participate in a spectrum auction or held active spectrum licenses as of September 2018. However, our analysis does not capture the extent that tribal entities may have obtained a license that is no longer active. To identify tribal entities that used unlicensed spectrum to deliver unlicensed service, we interviewed the tribal entities identified above. In addition, we obtained stakeholder views on the advantages and disadvantages of using unlicensed and licensed frequency bands and any barriers that tribal entities face in obtaining spectrum licenses by interviewing the selected stakeholders noted above. To determine the extent to which FCC promotes and supports tribal entities’ efforts to obtain and access spectrum, first, we reviewed FCC’s proposals in its ongoing 2011 Notice of Proposed Rulemaking In the Matter of Improving Communications Services for Native Nations by Promoting Greater Utilization of Spectrum over Tribal Lands and its ongoing 2018 Notice of Proposed Rulemaking In the Matter of Transforming the 2.5 GHz Band. We summarized public comments submitted, as of August 2018, by private and tribal providers, rural and nationwide industry associations, tribal associations, and tribal governments on FCC’s 2011 proposed rulemaking. We did not analyze comments on FCC’s 2018 Notice of Proposed Rulemaking because FCC was in the process of responding to these comments at the time of our review. Second, we reviewed rules that FCC officials identified that increased the availability of unlicensed and licensed frequency bands for broadband use and that may be particularly useful for tribal entities. These rules included FCC’s 2010 and 2012 rules related to TV white space spectrum and its 2015 rule and 2017 Notice of Proposed Rulemaking related to the Citizens Broadband Radio Services (CBRS) spectrum. We identified tribal entities that had been using CBRS frequency bands by reviewing FCC licensed data and TV white space frequency bands through interviews with tribal entities and regional consortia. Third, we identified FCC’s outreach activities to provide tribal entities with assistance on spectrum-related issues by interviewing FCC officials and reviewing documentation on the content of FCC-led trainings and workshops, e-mail correspondences, and related publications, such as public notices. Lastly, we interviewed FCC officials on the information that they collect, analyze, and report related to tribal use of spectrum and reviewed related documentation, including FCC’s Office of Native Affairs and Policy 2012 Annual Report and FCC’s license and auction data. We interviewed stakeholders, as noted above, and summarized their views of FCC efforts. We also compared FCC’s efforts against FCC’s 2018-2022 strategic plan, recommendations made in FCC’s National Broadband Plan, and Standards for Internal Control in the Federal Government related to using quality information. We conducted this performance audit from November 2017 to November 2018 in accordance with generally accepted government auditing standards. Those standards require that we plan and perform the audit to obtain sufficient, appropriate evidence to provide a reasonable basis for our findings and conclusions based on our audit objectives. We believe that the evidence obtained provides a reasonable basis for our findings and conclusions based on our audit objectives. We identified the spectrum frequency bands that the Federal Communications Commission (FCC) has made available for commercial broadband services and that FCC assigns licenses through auctions. Table 3 describes these licenses, including the number and date of related auctions. Mark L. Goldstein, (202) 512-2834 or goldsteinm@gao.gov.

Summary: In 2018, FCC estimated that 35 percent of Americans living on tribal lands lack broadband service compared to 8 percent of Americans overall. Broadband service can be delivered through wireless technologies using radio frequency spectrum. According to FCC, increasing tribal access to spectrum would help expand broadband service on tribal lands. GAO was asked to review spectrum use by tribal entities—tribal governments and tribally owned telecommunications providers. This report examines (1) tribal entities' ability to obtain and access spectrum to provide broadband services and the reported barriers that may exist, and (2) the extent to which FCC promotes and supports tribal efforts to obtain and access spectrum. GAO interviewed 16 tribal entities that were using wireless technologies. Selected entities varied geographically, among other characteristics. GAO analyzed FCC's license and auction data as of September 2018, reviewed FCC's rulemakings on spectrum for broadband services, and interviewed other tribal and industry stakeholders and FCC officials. The information presented is not generalizable to all tribes or industry participants. The tribal entities GAO contacted cited various barriers to obtaining spectrum licenses in bands that can be used to provide broadband services. According to its analysis of data from the Federal Communications Commission (FCC), GAO identified 18 tribal entities that held active spectrum licenses in such bands. For example, of these 18 tribal entities, 4 obtained licenses through secondary market transactions—that is, they bought or leased the license from another provider, and 2 obtained a license through an FCC spectrum auction. Licensed spectrum is generally preferred because it offers better quality of service compared to unlicensed spectrum; however, almost all of the tribal entities GAO contacted said that they are accessing unlicensed spectrum to provide Internet service. They identified barriers to obtaining licensed spectrum through auctions and secondary market transactions, barriers such as high costs and, in the case of secondary market transactions, a lack of information on who holds licenses over tribal lands. Because most spectrum allocated for commercial use has already been assigned, the secondary market is one of very few avenues available to tribal entities that would like to access licensed spectrum. FCC has taken steps to promote and support tribal access to spectrum. For example, FCC issued proposed rulemakings in 2011 and 2018 that sought comment on tribal-specific proposals, such as establishing tribal-licensing priorities and initiating processes to transfer unused spectrum licenses to tribal entities. However, FCC has not finalized these rules and is in the process of responding to comments to the 2018 rulemaking. Also, while FCC has made additional spectrum available for broadband use in recent years, tribal stakeholders cited limitations with the spectrum FCC has made available. For example, FCC allows broadband providers to operate in unused television broadcast bands on an unlicensed basis. While stakeholders GAO interviewed cited some advantages of these bands, such as being useful to reach remote customers, they also noted technical and cost limitations that reduced the potential to improve tribal access to spectrum. FCC stated that it is implementing spectrum initiatives and recognizes the importance of promoting a robust secondary market to improve communications throughout the United States, including tribal lands. However, GAO found that FCC has not collected data related to tribal access to spectrum, analyzed unused licensed spectrum that exists over tribal lands, or made data available to tribal entities in an accessible and easy manner that could be beneficial in their efforts to obtain spectrum licenses from other providers. By collecting data on the extent that tribal entities are obtaining and accessing spectrum, FCC could better understand tribal spectrum issues and use this information as it implements ongoing spectrum initiatives. Further, given that the secondary market is one of few ways for tribal entities to access licensed spectrum to be able to provide Internet service, FCC could promote a more robust secondary market by analyzing unused licensed spectrum over tribal lands and using that information to inform FCC's oversight of the secondary market. Additionally, by making information available on who holds spectrum licenses over tribal lands, FCC could remove a barrier tribes may face in attempting to obtain spectrum through the secondary market. FCC should (1) collect data on tribal access to spectrum; (2) analyze unused licensed spectrum over tribal lands; and (3) make information available in a more accessible manner that would promote tribes' ability to purchase or lease spectrum licenses over their lands from other providers. FCC agreed with the recommendations.
