Shure urged FCC action on wireless multichannel audio systems rules, as proposed in a 2021 NPRM (see 2104220056). “There is broad consensus in the wireless microphone community of manufacturers, technical experts, and users in support of technologies that deliver greater spectrum efficiency than what is currently available with narrowband technologies,” said a filing Wednesday in docket 21-115: “Such innovations are important to address the continually growing demand for wireless microphone technologies in a context in which access to suitable spectrum has been dramatically reduced and spectrum will continue to be constrained in the future.” Shure representatives met with staff from the Office of Engineering and Technology. The record “reflects support for different technical approaches to implementing WMAS rules and Commission staff will need to assess the likelihood of potential interference and weigh the trade-offs of each approach based on definitions of permissible power, bandwidth and spectral efficiency requirements,” Shure said.

Qualcomm submitted to the FCC Thursday a report on public tests of its 6 GHz automated frequency coordination (AFC) system, which it earlier announced would start in August (see 2308300018). Only the Electric Power Research Institute (EPRI) and AT&T Labs filed challenges, Qualcomm said. “Qualcomm was unable to replicate EPRI’s calculations” and differences are tied to test methodologies, the report said: “Out of 214 test vectors submitted, AT&T Labs only challenged 40 test vectors. For each test vector challenged, AT&T provided comparison results as figures and eventually provided detailed logs from their models, which were helpful for understanding and resolving the mismatches. AT&T engineers worked with Qualcomm to determine the source of the mismatches.”

CTIA sought tweaks to an FCC draft NPRM that tentatively concludes that a 100% hearing-aid compatibility requirement is “achievable,” set for a commissioner vote on Dec. 13 (see 2311220047). CTIA urged the FCC to adopt the compliance timeline in last year’s HAC Task Force Report (see 2212160063), which provides four years for manufacturers and five years for service providers for compliance from the effective date of the new rules. “Industry has achieved upwards of 90% HAC-rated handsets under the 2011 ANSI Standard and achieving those last few percentages of HAC-rated handsets under the new 2019 Standard will be much harder than the preceding 90%,” said a filing posted Thursday in docket 23-388.

CTIA ended a series of meetings with aides to the FCC commissioners on its concerns with the agency's draft robotexting order, noting sessions with staff for Commissioners Nathan Simington and Anna Gomez in a filing posted Thursday in docket 02-278. The concerns raised were the same as those expressed during meetings with the other offices (see 2312050033).

The U.S. Appeals Court for the D.C. Circuit granted the FCC’s Oct. 5 motion to dismiss Indian Peak Properties’ petition for review of a commission over-the-air reception device rule (see 2310240005), said the court's per curiam order Thursday (docket 23-1223). Indian Peak sought judicial review of two letter rulings issued by the Wireless and Media bureaus under delegated authority. But the challenged orders aren’t final, and the petition for review “is incurably premature” in light of Indian Peak’s application for review pending before the FCC, said the order. Under D.C. Circuit Rule 36, the disposition in the case won’t be published, it said. The court directed the clerk to withhold issuance of the mandate in the case until seven days after disposition “of any timely petition for rehearing or petition for rehearing en banc,” it said.

Mobile data traffic, estimated at 84 million terabytes monthly in 2022, is projected to hit 603.5 million TB per month by 2030, a compound annual growth rate of 27.9%, ResearchAndMarkets.com said Wednesday. Video alone is expected to reach 463 million TB per month in 2030, the report said: “The COVID-19 pandemic has significantly impacted mobile data traffic, with increased smartphone activity and internet dependence driving its growth. Mobile data traffic is a key component of the global telecommunications landscape, and understanding its market dynamics is crucial.”

T-Mobile is testing millimeter-wave spectrum on a 5G stand-alone network, collaborating with Ericsson and Qualcomm Technologies. T-Mobile said Wednesday it demonstrated download speeds greater than 4.3 Gbps without relying on low-band or mid-band spectrum to anchor the connection, using eight aggregated channels of high-band spectrum. In addition, it aggregated four channels of mmW for the uplink, reaching speeds exceeding 420 Mbps. T-Mobile noted that while high band “can deliver incredibly fast speeds because it offers massive capacity,” it doesn’t propagate well, “making it less ideal” for mobile phone users who are moving. T-Mobile said it’s testing its use in crowded areas like stadiums and for fixed wireless. “We’ve always said we’ll use millimeter wave where it makes sense, and this test allows us to see how the spectrum can be put to use in different situations like crowded venues or to power things like fixed-wireless access when combined with 5G standalone,” said Ulf Ewaldsson, president-technology at T-Mobile.

FCC Commissioner Nathan Simington Wednesday called for a cyber trust mark program that “will help transform the currently dismal connected device security landscape.” The agency recently took comment on a proposed cybersecurity labeling program for smart devices (see 2311130034). The program should have “robust requirements, especially that manufacturers make legally binding commitments to maintaining the security of their products after the time of sale,” Simington said in a news release: “Absent such binding, ongoing commitments, the label would be yet another cybersecurity standard that fails to meaningfully improve the security landscape.” The program shouldn’t be used as a “safe harbor for negligent practices, or to otherwise preempt state law,” which “would undermine incentives for device manufacturers to be vigilant about security threats,” he said.

Ericsson urged FCC approval of a Samsung waiver for a 5G base station radio that works across citizens broadband radio service and C-band spectrum (see [Ref:2309130041). Approval would mean radios using less energy with a “much smaller cell site footprint, thereby facilitating faster zoning review and easier siting,” Ericsson said in a filing posted Wednesday in docket 23-93. Ericsson noted it has filed a similar waiver request.

Axon sought waivers of FCC rules for a small surveillance drone, a surveillance robot and a camera that can either be fixed or pole-mounted, that use the 5725-5850 MHz band. All three would be sold strictly to law enforcement agencies, the company said. Axon hopes to use higher power levels than allowed under FCC rules. The devices also slightly exceed the out-of-band emission limits at the band's upper and lower edges, Axon added. “None of the three devices will begin to transmit video signals in the 5725-5850 MHz band absent an affirmative command by the user,” Axon said: “The command-and-control link is maintained using an FCC-approved 900 MHz handheld controller that complies with Part 15 of Commission’s rules and, therefore, is not addressed further in this request.” The undocketed filing was posted Wednesday.
