The Edison Electric Institute and other groups representing incumbent users of the 6 GHz band asked the FCC to delegate the Wireless Innovation Forum or another inter-industry body to develop “standardized implementations” for automated frequency coordination system propagation models. The groups said they appreciate “that the AFCs are collaborating to develop a single interference reporting process rather than each developing its own -- or not having a defined process at all.” But collaboration shouldn’t mean just AFCs, said a filing posted Tuesday in docket 21-352: “It should include representatives of the incumbents whose systems are entitled to interference protection under FCC rules.” Also signing the filing were the Enterprise Wireless Alliance, the International Association of Fire Chiefs and the Utilities Technology Council.
Policymakers shouldn’t forget the potential of very high frequency spectrum, the mmWave Coalition said last week in response to the National Science Foundation’s request for information (RFI) on the national spectrum research and development plan, which is part of the national spectrum strategy. The comments have yet to be posted by NSF. Most 5G and 6G discussions so far are focused on lower frequencies, the coalition said. “A key reason for this is that it is hard to justify a business case for sub-THZ mobile spectrum use at present as there are now basic technical questions, technological hurdles, and cost issues, yet these are fertile and active areas of research which may eventually lead to compelling opportunities for mobile use in this spectrum,” the group said. The coalition cited a growing need for wireless backhaul, “especially in rural, underserved areas often where fixed wireless access is vital for rural households, and often backhaul requirements cannot always be implemented in fiber technology, due to installation urgency requirements, local terrain features that delay or block installation, cost, or short term requirements that make fiber optic installation uneconomical.” The Dynamic Spectrum Alliance said the RFI is on target in the areas it suggests for research. “Efficiency, dynamic spectrum access and management, automated interference mitigation, and coexistence modeling are all areas in which the DSA and our members have keen interest and extensive experience,” the alliance said: “We also fully support efforts to study the economic-, market-, social-, and human-centric aspects of increasing spectrum access.” DSA called on the NSF to take into account innovative licensing frameworks that are already working, including the citizens broadband radio service band and 6 GHz. “Given the historical success of the variety of spectrum sharing techniques in different bands designed to protect different incumbents … there is no one size fits all solution to spectrum sharing,” DSA said. AT&T urged the administration to more clearly define the term dynamic spectrum sharing. The definition should include an “examination of full-power licensed use” and “development of a basis for predictable times and/or geographies in which dynamically shared spectrum can be used,” AT&T said. The carrier urged more work on interference mitigation techniques and not restricting research to “mere ‘on/off’ spectrum access controls.” The definition should seek “to define co-channel and adjacent channel interference environments to incorporate into network design and operation.”
The American Action Forum questioned how the U.S. really fared during last year’s World Radiocommunication Conference. “Delegations from across the world largely adopted China’s spectrum approach in the mid-band, allocating the upper part of the 6 GHz band for 5G services,” a report released Tuesday said. Jeffrey Westling, director-technology and innovation policy, is its author. While the U.S. has allocated the entire 6 GHz band for unlicensed use, actions at the last WRC may keep other countries from following the U.S.’s lead, it said. “Countries don’t have to allocate the band for 5G but can’t allocate spectrum in a manner that would cause harmful interference to 5G operations in neighboring jurisdictions,” the paper said: “Equipment manufacturers will have less incentive, and potential profit, in designing and manufacturing additional unlicensed equipment that operates in the upper portion of the band, as fewer countries will allow the use of that technology.” The U.S. struggled to persuade nations to adopt its approach “because it lacks a robust plan to commercialize spectrum in the mid-band for exclusive licenses, shared models, or even more unlicensed,” the paper argues: “Leading into the conference, the only mid-band spectrum teed up for commercialization was 3.1–3.45 GHz, and the DOD pushed back on efforts to allow commercialization of the band,” and without auction authority the U.S. “lacked stability in spectrum policy, perhaps concerning potential allies that desired a robust plan for mid-band.”
Senate Commerce Committee ranking member Ted Cruz, R-Texas, and Communications Subcommittee ranking member John Thune, R-S.D., filed their long-circulating 2024 Spectrum Pipeline Act Monday with some changes from a draft version proposed in the fall (see 2311220063). The proposal drew sharply divided reactions from communications policy stakeholders. Some lobbyists suggested Cruz and Thune filed the measure Monday to get ahead of NTIA's planned release later this week of its implementation plan for the Biden administration's national spectrum strategy (see 2403050048).
Wi-Fi advocates strongly opposed a December request from Axon Enterprise for a waiver allowing it to market three investigation and surveillance devices to law enforcement agencies. These devices would operate at higher power levels than allowed under FCC rules in heavily used 5 GHz spectrum. The FCC Office of Engineering and Technology sought comment in February (see 2402060082). Oppositions were posted on Friday in docket 24-40. Axon didn’t comment Friday.
Seventeen cable companies and other Wi-Fi advocates, spectrum sharing advocates, and defense and aeronautics companies Monday released a letter sent to NTIA about implementation of the national spectrum strategy. It warned against “anti-competitive efforts, modeled after China’s goals, to clear the 3 GHz and 7 GHz bands for exclusive licensing to a small handful of legacy carriers.” NTIA is set to release the plan March 14 (see 2402090059). “The decisions made … will directly affect the nation’s ability to maintain and promote our global competitiveness, national security, and national security technology leadership with our allies,” the letter said: “We urge the NTIA to adopt an Implementation Plan that is aggressive in expanding the pie for a wide variety of public, commercial, and national security uses.” The plan should focus on “accelerating the development and adoption” of spectrum sharing technologies and coexistence frameworks, the letter said. It noted the success of sharing in the 6 GHz band and the citizens broadband radio service band. Signers included the American Library Association, Charter Communications, Comcast, Cox Communications, the Dynamic Spectrum Alliance, Federated Wireless, Deere & Company, Lockheed Martin, NCTA, the Open Technology Institute, Public Knowledge, Midcontinent Communications, the Schools, Health & Libraries Broadband Coalition, Spectrum for the Future, WifiForward and the Wireless ISP Association.
The Wireless ISP Association praised the FCC's Friday order approving the launch of automated frequency coordination providers in the 6 GHz band (see 2402230050). “WISPA expects that this newly expanded marketplace will bring unimagined internet capacity quickly, flexibly and cost-effectively to places once thought ‘off the map,’” the group said: “This will enable connection of more Americans to life-bettering broadband.” WifiForward also praised the order. The databases launched “build upon a long line of innovations that the FCC has authorized to promote coexistence of different applications, which means better, faster connectivity for consumers, economic value and greater peace of mind for incumbent operators,” it said.
The FCC Office of Engineering and Technology Friday approved the applications of seven 6 GHz automated frequency coordination (AFC) providers to launch operations by standard-powered unlicensed devices, closing out a multi-year process. The development is one of the most significant for 6 GHz since the 2020 FCC order opening the spectrum for unlicensed use, industry officials said.
Delegates to the World Radiocommunication Conference last year dealt with a slew of proposed future agenda items for WRC 2027, Michael Mullinix, CTIA vice president-regulatory affairs, said during a panel discussion at an FCBA webinar Wednesday (see 2402140051). Similarly, an unusually large number of items on the 2023 agenda remained from 2019, Mullinix said. The U.S. delegation offered a “whopping” 18 proposals for the 2027 agenda; more than 40 proposals came from other regions, he said. “That’s a lot of proposals, and more importantly, a lot of priorities for each country that submitted them,” he said. The goal is narrowing the focus to a “manageable” 15 to 18 topics during the four-year study period, Mullinix said. “The work is already underway toward WRC-27 decisions today,” he said. It’s already clear that the biggest focus of the U.S. in 2027 will be making more mid-band spectrum available for full-power licensed use, he said. Recent studies suggest U.S. wireless networks will “fall short” of meeting expected demand “absent new spectrum access,” he said. Mullinix said 7/8 GHz, which will get further study under the administration’s national spectrum strategy (see 2402090059), is “now the global harmonization target for expanding capacity for 5G and beyond.” Spectrum policy is critical to ensuring that trusted equipment suppliers have “the global economies of scale needed to compete, and don’t have to develop unique equipment just for the U.S. market,” he said. HWG’s Tricia Paoletta said it’s also clear the U.S. will continue pressure at the next WRC to protect the 6 GHz band for Wi-Fi and unlicensed use. “The U.S. is also the global leader in the Wi-Fi ecosystem,” which next year is expected to be worth $5 trillion, she said. U.S. companies “hold the vast majority of intellectual property rights … so it’s a very critical area for the United States’ economy too,” she said. Chinese operators, led by Huawei, will continue pressuring other countries to allocate the 6 GHz band for international mobile telecommunications, Paoletta said. Hogan Lovells’ George John noted that 7/8 GHz is already used for unlicensed operations, earth exploration and space research. It's important because the amount of space research services spectrum available is limited, he said. All the bands to be studied for licensed use will present complications for policymakers, John predicted. U.S. leadership in 5G and 6G is “super important,” but “we also need to love the incumbents,” he said.
The U.S. has slowed down on providing licensed spectrum for 5G, and on some levels “stopped entirely,” said Umair Javed, CTIA senior vice president-spectrum at the State of the Net conference Monday. Some say “all the low-hanging fruit has been plucked” and “we have to accept tighter times ahead,” Javed said, but he disagrees. He noted that since 2018, U.S. carriers have invested $160 billion in their networks, “the largest investment in our nation’s technology base in history.” Making the lower 3 GHz and 7/8 GHz bands available for licensed use would reverse a negative trend, Javed said. U.S. policymakers should look at ways to “segment” the lower 3 GHz and create “a full-power, licensed opportunity in the 3.3-3.45 GHz range,” he said. The 7/8 GHz band offers “an opportunity for the U.S. to plan ahead and lead in the development of a new global 5G band,” he said. That band has been identified by the ITU “as a future harmonization target” and would let the U.S. “match global deployments planned in the 6 GHz band, meaning we will realize economies of scale and be able to participate in a broader equipment market,” he said.
