RS Access CEO Noah Campbell urged quick approval of 5G use of the 12 GHz band, speaking with an aide to FCC Chairwoman Jessica Rosenworcel, said a filing posted Friday in docket 20-443. “I expressed confidence that 5G mobile broadband operations, nongeostationary orbit fixed-satellite service, and Ku-band Direct Broadcast Satellite operations can share the 12 GHz band and coexist in the band,” said a filing posted Friday in docket 20-443.

Google representatives urged adoption of revised rules for short-range field disturbance sensor radars in the 60 GHz band, speaking with an aide to FCC Chairwoman Jessica Rosenworcel. The company had a similar call with Office of Engineering and Technology staff earlier in the week (see 2204260074). “Coexistence is possible across the multitude of technologies, including the several varieties of low-power radars, that can operate in the 60 GHz band,” said a filing posted Friday in docket 21-264.

To assuage National Public Safety Telecommunications Council concerns about possible interference to public safety operations in the 851-854 MHz band segment (see 2108090058), Gogo Business Aviation is fine with a waiver condition for notification of public safety licensees in the band segment, the company told FCC Wireless Bureau representatives, per docket 21-282 Friday. Gogo is seeking a waiver on power limits for air-to-ground operations in the 849-851 MHz and 894-896 MHz bands. It said the proposed condition, which would have Gogo notify licensees within 10 miles of a base station about deployment and how to submit inference complaints, should make public safety operators aware of possible inference and about how to abate it in coordination with Gogo.

Qualcomm urged the FCC to ignore arguments by Continental Automotive that limiting part of the 5.9 GHz band exclusively to cellular vehicle-to-everything use could have negative implications because of intellectual property concerns (see 2204060038). “The FCC should not entertain Continental’s requests that the agency adopt regulations or broad pronouncements relating to private patent licensing disputes because the U.S. court system is addressing those issues and the FCC lacks the legal authority and expertise to do so,” said a filing posted Thursday in docket 19-138. “Continental fails to inform the FCC of Continental’s federal antitrust case, including the recent decision from the U.S. Court of Appeals for the Fifth Circuit affirming the dismissal of Continental’s lawsuit seeking relief that substantially overlaps what Continental is asking the FCC to implement,” Qualcomm said. Company representatives spoke with staff from the FCC offices of General Counsel, Engineering and Technology, and Economic Analysis.

CTIA and member companies defended the wireless industry’s voluntary network resiliency cooperative framework, in calls with an aide to FCC Commissioner Brendan Carr and Chief Debra Jordan and others from the Public Safety Bureau. An NPRM approved by commissioners in September (see 2109300069) asks about potential improvements, including whether to codify “some or all of the Framework.” The industry representatives discussed “various ways that wireless providers continue to invest in infrastructure, employees, tools, and improved coordination that are necessary to maintain wireless services for consumers and public safety during emergencies and disasters,” said a filing posted Thursday in docket 21-346. “These investments include densifying networks with overlapping cell sites, pre-positioning deployable equipment, and enhancing coordination with other communications providers, electric utilities, and federal and state emergency managers.” The framework is “a critical part of the collaboration that jumpstarts response and recovery,” they said. AT&T, T-Mobile and Verizon officials took part in the calls.

T-Mobile filed at the FCC its list of licenses it believes should be offered during the upcoming 2.5 GHz auction, in response to the recent revised list from the FCC (see 2204150048). T-Mobile “appreciates the work that the Commission’s staff has invested in preparing for this important auction, including by refining the list of products that will be available and making available a mapping tool,” said a filing posted Wednesday in docket 18-120. The FCC will offer some 8,000 licenses in the auction, which starts July 29.

Top officials from the National Sheriffs' Association spoke with FCC Chairwoman Jessica Rosenworcel about the future of 4.9 GHz band, the subject of a comment cycle that wrapped in January (see 2201120049). “NSA discussed the importance of preserving 4.9 GHz for public safety use and the importance of nationwide public safety,” said a filing Wednesday in docket 00-32.

Google representatives urged the FCC to adopt revised rules for short-range field disturbance sensor radars in the 60 GHz band (see 2110180062), in a meeting with Office of Engineering and Technology staff. “Modifications to the rules are necessary to realize the full potential of the 60 GHz band” and “updated rules should seek to maximize reasonable coexistence and technological neutrality among unlicensed technologies,” said a filing posted Tuesday in docket 21-264. “Coexistence is possible across a full panoply of technologies, including the several varieties of low-power radars that can operate in the band,” Google said.

NTIA’s Institute for Telecommunication Sciences (ITS) selected Rakuten Mobile USA to provide distributed and central units for interoperability testing by 5G Challenge host lab CableLabs, said a Tuesday release. The institute is hosting the challenge, in collaboration with DOD, “to accelerate the adoption of open interfaces, interoperable components, and multi-vendor solutions,” NTIA said. In the first-year event, NTIA and ITS will award up to $3 million “to contestants who submit hardware and/or software solutions for one or more … 5G network subsystems.” Interested contestants can still submit white papers to Challenge.gov by 7 p.m. EDT May 5 to take part in the challenge, NTIA said.

Increased spectrum congestion shows the need for the FCC to put more emphasis on the use of probabilistic interference assessments, said Jeffrey Westling, American Action Forum technology and innovation policy director, in a report. Traditional spectrum management decisions “were based on impact estimates using deterministic, single-value calculations that employ worst-case scenarios,” he said Monday: “This approach results in an overly conservative management regime that often prevents the deployment of new services even if the likelihood of harmful interference, and the potential impact if harmful interference did occur, remained relatively insignificant.” Probabilistic interference assessments “better account for the actual operating parameters in the field, as well as the actual impact the interference will have on operations,” he said. They “provide regulators with a more complete picture of the radio environment when determining whether new services can be deployed and operate, allowing for increased spectrum efficiency in the United States.”
