Industry commenters urged the FCC to avoid imposing additional outage reporting requirements. Reply comments to a January Further NPRM (see 2401250064) were filed this week in docket 21-346.

The FCC and NTIA are working together as well as Ira Keltz has seen in his 30 years of government service, but the deputy chief of the FCC’s Office of Engineering and Technology said finding consensus on spectrum issues remains difficult. Keltz spoke Wednesday at the International Symposium on Advanced Radio Technologies (ISART) conference in Denver. Echoing Keltz was Derek Khlopin, NTIA deputy associate administrator in the Office of Spectrum Management.

The FCC Wednesday notified certified spectrum access system administrators in the citizens broadband service band that they are now permitted to implement changes to the existing aggregate interference model used to protect federal operations in the band. Among the changes, SAS administrators may now assume an 80% time division duplex activity factor and 20% network loading factor for each CBRS device in the aggregate interference calculation, said a notice from the Wireless Bureau and Office of Engineering and Technology. Administrators may use median irregular terrain model terrain dependent propagation loss “using reliability and confidence factors of 0.5 -- to calculate the aggregate received power levels” within a protection area. The FCC urged administrators to submit a demonstration of their ability to implement the new testing parameters in docket 15-319. NTIA approved the changes in a letter to the FCC posted Wednesday. “The changes outlined … will expand Internet access to more people across the country,” said NTIA Administrator Alan Davidson: “They could not have been implemented without the collaboration of the Navy and our ongoing coordination with the FCC.” The change will expand use of the band to tens of millions of Americans, said FCC Chairwoman Jessica Rosenworcel. “The CBRS dynamic spectrum sharing framework is already fertile ground for wireless innovation, and through collaboration with [DOD], NTIA, and stakeholders, we are expanding opportunities for reliable spectrum access while also ensuring that federal incumbents remain protected,” she said. The changes authorize service to approximately 72 million more POPs and expand the total unencumbered CBRS area to roughly 240 million POPs nationwide, the agencies said. CBRS is a prime example of how industry and government can coordinate on spectrum, Ira Keltz, deputy chief of the FCC’s Office of Engineering and Technology said Wednesday at the International Symposium on Advanced Radio Technologies (ISART) conference in Denver. When CBRS started, the initial exclusion zones were “huge” and would have excluded 75% of POPs, he said. NTIA, working with engineers, was able to reduce the size of the zones so that CBRS made more sense, industry was willing to invest, and the Navy felt comfortable that its radars would be protected, Keltz said. “It just really comes down to people being open-minded,” he said. Derek Khlopin, NTIA deputy associate administrator, noted the work to make CBRS work better. “These improvements we’ve made have been phenomenal,” he said, also at the ISART conference. He credited the Navy for its willingness to work with the NTIA and the FCC. “With little ‘greenfield’ spectrum available yet ever-increasing demand for spectrum-driven utilizations, sharing allows more efficient use of limited spectrum resources,” emailed Richard Bernhardt, vice president-spectrum and industry at the Wireless ISP Association: The development “will provide more predictability and allow for approximately 72 million additional people to be covered by CBRS without having to move or change power due to Federal operations.”

The work that industry and government are doing addressing “clutter analysis” and dynamic sharing is critical to the future of wireless, Shiva Goel, NTIA senior spectrum adviser, said at an International Symposium on Advanced Radio Technologies (ISART) conference on Tuesday. Goel said the government, working with industry, is making progress. The Denver conference's main focus this week is on propagation models that account for the impact of clutter, including foliage and buildings, on wireless signals.

CTIA, the Ohio Telecom Association, USTelecom, NCTA, the Wireless ISP Association and other ISP groups asked the 6th U.S. Circuit Appeals Court to stay the FCC’s net neutrality order (see 2406100044). The FCC wants to move the case to the D.C. Circuit and has declined to stay the order, which takes effect July 22. The agency “has asserted total authority over how Americans access the Internet,” according to a joint motion filed Monday (docket 24-3450). “That is not hyperbole,” the groups said. The order “is only the latest jolt in a decade of regulatory whiplash for ISPs,” the associations said. After nearly 20 years of a light-touch approach to regulating the internet, in 2015 the FCC asserted for the first time authority over high-speed internet access service under Title II of the Communications Act, the filing said: Before the U.S. Supreme Court “could weigh in, a new Administration reverted to the traditional light-touch approach. Now, after another change in Administration, the Commission is back to a heavy hand, promising to make even more aggressive use of its claimed powers.” The court should stay “the latest flip-flop pending judicial review” since “petitioners are overwhelmingly likely to succeed on the merits,” the ISPs said. They argue that the order should be rejected under the Supreme Court’s evolving major questions doctrine. “Because the Commission cannot point to clear congressional authorization for applying common-carrier regulation to the Internet, the Order is unlawful,” they said.

DOD Chief Information Officer John Sherman, who has led the department’s work on opening the lower 3 GHz band for 5G, is leaving government for academia. He will become dean of the Bush School of Government and Public Service at Texas A&M University. But industry experts agree that the personnel change likely won’t prove disruptive because Leslie Beavers, principal deputy CIO, will replace Sherman on an acting basis.

The FCC urged the 6th U.S. Circuit Appeals Court Friday to move the challenge to the FCC’s net neutrality order to the D.C. Circuit (docket 24-3450). The FCC also issued an order declining to stay the rules, which take effect July 22, pending judicial review.

Selection of the 6th U.S. Circuit Appeals Court to hear industry challenges to the net neutrality order may bode well for industry. Still, many questions remain, including which judges will hear the case and whether arguments are ultimately held in the Ohio-based court, industry experts said Friday.

The FCC on Thursday approved 3-2 a three-year, $200 million cybersecurity pilot program for schools and libraries. Commissioners Brendan Carr and Nathan Simington dissented, as some had predicted (see 2406040039). The two cited concerns with the FCC using E-rate program funds for the effort. Commissioners Geoffrey Starks and Anna Gomez indicated changes were inserted into the pilot rules at their request.

Momentum is growing behind the launch of stand-alone 5G networks, Heavy Reading analyst Ruth Brown said during a Light Reading webinar on service assurance Thursday. The wireless industry remains in a transitional stage, she said. Carriers are “very eager to start monetizing 5G” and offer “long-awaited advanced 5G services,” she said. “Operators are still working through this long investment cycle,” she said. Carriers feel increasing pressure to ensure they can monitor network operations and “respond dynamically, in real time, to service needs,” Brown said. Moving to the cloud will require service assurance changes and orchestration and life-cycle management, she said. Support “really needs to move to this dynamic, real-time model” and “we need to think about how we’re going to get there.” Brown said automation will be critical, but most carriers report they are already automating their networks. Providers' top priorities are tools for developing and testing software network functions and network diagnostics and the resolution of problems, she said. Cloud native and virtual networks are becoming “more normal” for carriers, said Mark Watts, a member of the Verizon technical staff. “We essentially look at each individual application and whether it fits into the cloud-native” environment, he said. Software-based applications are more nimble than legacy, hardware-based applications, he said, stressing the importance of testing. Verizon prides itself on its reliable network “and that starts with service assurance,” Watts said. “Software testing is … more and more important as we’re embarking on this cloud-native journey,” he said. “Ongoing monitoring” of the cloud-based system “continues to be a very high priority" for Verizon and operators across the globe, Watts said. As carriers introduce different hardware and software into their networks, interoperability is also critical to ensure “the longevity and ongoing reliability of the network,” he said. 5G slicing remains “a hot topic,” as is ensuring that the service offered through slices is automated and “supported more quickly and in a more nimble manner.” Slicing could offer increased security, better gaming, high-throughput or ultra-reliable services beyond what is typically available on Verizon’s network, he said.
