The FCC got dozens of comments on an August NPRM from wireless carriers, tech companies and others on further changes to rules for the citizens broadband radio service band (see 2408160031). In filings posted through Thursday in docket 17-258, commenters disagreed sharply on a proposal by carriers to more closely harmonize CBRS rules with those for the adjacent 3.45 GHz and C-band.

The future success of the wireless industry depends on having a single standard worldwide for mobile communications, Adrian Scrase, former chief technology officer at the European Telecommunications Standards Institute, said Tuesday during an RCR Wireless industrial 5G forum. Multiple standards are “just not tenable if we’re to have economic success,” said Scarse, now a consultant for the Global Mobile Suppliers Association.

Senate Intelligence Committee Chairman Mark Warner, D-Va., said during a Thursday Punchbowl News event he would prefer the chamber pursue a middle-ground between the Spectrum and National Security Act (S-4207) and 2024 Spectrum Pipeline Act (S-3909) as a legislative package for renewing the FCC’s lapsed airwaves auction authority. He also voiced concerns about the Biden administration’s implementation of $65 billion in broadband money from the Infrastructure Investment and Jobs Act, echoing criticisms congressional Republicans raised about how long it has taken for funded projects to come online.

Senate Commerce Committee ranking member Ted Cruz, R-Texas, will likely redirect the panel's airwaves legislative focus toward a version of his 2024 Spectrum Pipeline Act (S-3909) next year should Republicans control the Senate after the Nov. 5 elections and he becomes chairman. Cruz could face continued headwinds from DOD's staunchest Capitol Hill backers if he pursues legislation similar to S-3909, lobbyists and others predicted. Current Senate Commerce Chair Maria Cantwell, D-Wash., hopes she can attach her rival Spectrum and National Security Act (S-4207) to an end-of-year omnibus package (see 2409170066).

The Biden administration is moving forward on the national spectrum strategy, in some cases more quickly than is widely recognized, Shiva Goel, NTIA senior spectrum adviser, told the Mobile World Congress in Las Vegas last week. Goel’s comments build on the remarks of NTIA Administrator Alan Davidson at MWC (see 2410090045). “We're hard at work already on lower 3 and 7 and 8 [GHz],” Goel said. “We're bringing lower 37 [GHz] to a close” and “18 GHz is in full swing already, and then there's everything else.” Goel said DOD, which is working with NTIA on the lower 3 GHz study, hasn’t been “secretive” about its “preference for a … solution” based on dynamic spectrum sharing. “We're supporting” DOD “in building a demo of that capability,” but “that doesn't mean we can't also collaborate on other options for the band.” The strategy’s research and development plan is in its final stages, he said. On staffing, “we're getting the agencies together to spot gaps and ways to fill them to make sure we have people in government able to do this work far into the future.” Goel continued: “Our spectrum problems aren't getting any easier.” The relationship between NTIA and the FCC “is as good as I've ever seen it,” said Ira Keltz, the commission’s new acting chief engineer. The No. 1 priority is the proposed spectrum pipeline and the FCC’s Spectrum Steering Team, which he co-chairs, is hard at work, Keltz said. “We've got plenty of staff at the commission completely engaged in all the activities that are going on.” The top priorities are the lower 3 and 7.8 GHz studies, but the FCC is also focused on 37 GHz, he said. “There's still a ways to go” on the strategy, said Will Johnson, Verizon senior vice president-federal regulatory and legal affairs, “but there [are] also things to celebrate.” The wireless industry knows it will need about 1,500 MHz of mid-band spectrum over the next 10 years, and the pipeline “still remains fairly uncertain,” Johnson said: “We know some bands that are being studied. … But in terms of knowing which bands are actually going to make their way all the way through to commercial use, to auction, we're pretty far from having that kind of clarity at this point.” Luciana Camargos, GSMA head of spectrum, called for more leadership from the U.S. During the World Radiocommunication Conference last year, the U.S. message was that it didn’t want international mobile telecommunications in the 6 GHz band, but it failed to offer alternatives, Camargos said. The U.S. “didn't even support the new agenda item” looking at 4, 7 and 15 GHz, she said: “To me, that's very relevant. … If you don't support looking forward, how can you lead on this?” Keltz said the FCC understands wireless industry concerns about a spectrum pipeline. "We need high-powered dedicated spectrum," he said: "I think we need a little of everything. ... We need to make sure that our unlicensed industry has spectrum they can use." CTIA and GSMA co-sponsor MWC.

Industry officials continued questioning AT&T’s Wednesday proposal that calls for major changes in how 3 GHz, including the citizens broadband radio service band, is configured (see 2410090037). Monisha Ghosh, University of Notre Dame engineering professor and former FCC chief technologist, said AT&T's proposal leaves some questions unanswered. While in principle it’s “desirable to have high-power and low-power users separated by one boundary, the AT&T proposal doesn’t address how the existing Navy radars in the CBRS band will be protected” or “relocated and how spectrum sharing in 3.1-3.45 GHz will be implemented,” Ghosh told us, noting there are now 120 different kinds of radar in the band. Ghosh warned against drawing conclusions before the administration completes its study of the lower 3 GHz band called for in the national spectrum strategy. Moreover, Ghosh disagreed with AT&T that CBRS is "underutilized.” Relocating CBRS devices into another band that’s not an existing 3rd Generation Partnership Project band wouldn’t be a “trivial” problem, she said. Meanwhile, Public Knowledge Senior Vice President Harold Feld wrote in an email, “When you have a hammer, everything looks like a nail,” and when you’re a carrier “everything looks like it should be optimized for mobile broadband.” Feld added, “CBRS was designed to permit new kinds of innovation by different actors, such as stadiums, large warehouses, ports, or enterprise customers looking to run their own private networks.”

FCC Commissioners Nathan Simington and Geoffrey Starks warned the Mobile World Congress in Las Vegas that the FCC’s loss of general spectrum auction authority last year is hampering U.S. competitive efforts against major rivals in the 6G race. CTIA President Meredith Baker sounded a similar theme at the beginning of the conference, which CTIA sponsors with GSMA (see 2410080044).

NTIA remains “on track” to deliver on initial commitments under the national spectrum strategy that the Biden administration released in November (see 2311130048), NTIA Administrator Alan Davidson said at the Mobile World Congress in Las Vegas. Davidson also defended the administration’s progress under the $42.5 billion broadband equity, access and deployment (BEAD) program, a recurring target of Republican criticism (see 2409270032).

CTIA President Meredith Baker warned Tuesday that the U.S. will fall behind other countries unless Congress restores FCC auction authority, in remarks to the Mobile World Congress in Las Vegas. Baker quoted Paul Milgram, the economist whose work led to the first spectrum auction. The loss of auction authority is “nuts,” she said. The agency’s auction authority lapsed in March 2023 (see 2303100084).

Spectrum is critical to national security and the development of trusted technology, the Center for Strategic and International Studies says in a new paper. The security of the U.S. “as a market democracy is at stake,” CSIS argues. The U.S. is “currently in danger of falling behind China in mid-band licensed spectrum, which supports wide-area coverage and is essential for bringing mobile services and technologies to every part of the country,” the paper argues: “This shortfall poses a grave threat to the security of U.S. and allied network infrastructure.” CSIS stresses the importance of global harmonization of spectrum and scale for a trusted supply chain. China understands the importance of licensed spectrum for wideband networks and has set aside 2.5 times more mid-band spectrum for licensed use than is available in the U.S., CSIS says. The U.S. “is becoming a mid-band spectrum ‘island,’ operating largely outside the core globally harmonized spectrum bands,” CSIS warns. “If this trajectory continues, the U.S. technology ecosystem will be confined to a U.S.-only spectrum ‘dialect’ that lacks global influence and scale.” CSIS highlights the importance of the 7/8 GHz band as “a key opportunity” for the U.S. “to champion future harmonized capacity that can bolster its domestic wireless capabilities and support economies of scale for its trusted vendors.” That band has been a primary target of wireless carriers in the U.S. CSIS said it plans a second part to the paper, which will cover sharing in the lower 3 GHz band, the other top target of carriers. CTIA said it and its members support CSIS's conclusions.
