The FCC Office of Engineering and Technology on Monday approved a request from Broadcom, Wi-Fi Alliance Services and the Wireless Broadband Alliance to modify their open automated frequency coordination (AFC) code, which determines available power spectral density for 6 GHz standard power devices. The three sought the change in March (see 2404150050). OET acknowledged the Fixed Wireless Communications Coalition's concerns (see 2404150050). FWCC argues that a complete report detailing the proposed changes would “ensure transparency and without said report, incumbent licensees and other interested parties cannot fully consider an AFC’s proposed changes,” OET said: “Given that the modifications were minor corrections, and OET’s internal analysis found no discrepancies, we find that additional testing is not needed.”

T-Mobile told the FCC it has made “significant progress” on meeting its nationwide 5G network deployment milestones. It's a regulatory requirement of T-Mobile's acquisition of Sprint that the milestones are within six years of the deal's closing date. T-Mobile completed the buy four years ago (see 2004010069). “Since the third anniversary of the merger closing, T-Mobile has continued to deploy 5G service over its low-band and mid-band spectrum to the benefit of consumers across the country, resulting in extensive and nearly nationwide 5G coverage of the vast majority of Americans,” a filing Friday said (docket 22-211). T-Mobile reported an increase in its low-band 5G coverage area by approximately 0.6% since the last report and said it’s within 0.8% of meeting the 6-year milestone requirement of 99% of POPs nationwide. In addition, the carrier said its mid-band 5G coverage is at 94.1% of U.S. POPs, already besting the milestone requirement of 88%. T-Mobile reported it has met requirements for 5G sites nationwide and low-band/mid-band 5G spectrum averaged over all sites. But the data on both of these milestones was redacted from the report. The provider said it has also met all its rural 5G network deployment milestones and is well on the way to satisfying requirements for in-home broadband service. In a second filing, T-Mobile also requested keeping the redacted data from public disclosure. "The identified information is extremely sensitive, proprietary information about how T-Mobile is deploying its 5G network -- its most important competitive asset -- including how it is prioritizing deployment of its network infrastructure and bands of spectrum, the extent of its network coverage, the performance of its network, as well as how T-Mobile is deploying and marketing its In-Home Broadband Service," T-Mobile said.

Dahua Technology and IPVM remain at odds on Dahua USA’s request for confidentially on its compliance plan with FCC supply chain security rules (see 2310130042). Dahua provided additional information last week, which it said makes IPVM’s objections “now largely moot in light of” the “voluntary disclosures.” Parts of the plan remain redacted. While Dahua released some previously redacted information, questions remain, IPVM said in a filing posted Thursday in docket 21-232. Among the information redacted is a list “of the entities in Dahua USA's new control structure,” IPVM said: “We cannot be certain if this is similar to the corporate ownership Dahua has just disclosed. Dahua provides no further justification for this redaction, meaning it hinges on the same basis of vague commercial confidentiality it has now abandoned for other information.”

Ericsson’s Cradlepoint said T-Mobile will use its Connected Workplace gear as part of the carrier’s fixed wireless access offering for business customers, Cradlepoint said Thursday. Devices will include X10 5G FWA and E300 routers and W1850 and W1855 adapters, which can boost 4G and 5G connections. T-Mobile is also offering Cisco Meraki connected workforce devices.

With hurricane season underway, AT&T said Thursday it added a 45-foot custom-built landing craft to its maritime fleet that can carry equipment to a coastal area after disaster strikes. The landing craft “is part of the more than 750 pieces of specialized response equipment that traverse land, sea and air and can quickly deploy before, during and after any storm,” the carrier said. AT&T is also adding enhanced features to FirstNet push-to-talk and messaging, “introducing new features such as discreet listening and enhanced group and interagency coordination.”

The FCC on Thursday approved environmental sensing capability sensor deployments and coverage plans for Federated Wireless in Hawaii in the citizens broadband radio service band. The Wireless Bureau and Office of Engineering and Technology in coordination with NTIA and the DOD made the approval. Federated has satisfied the sensor coverage requirements to protect DOD operations in nine dynamic protection areas in the state and Pearl Harbor, the notice said. Federated on Wednesday asked for an extra six months, from June 30 to Dec. 31, to launch operations. The extension “is necessary to allow Federated Wireless sufficient time to complete construction of its ESC network in Hawaii, which… is taking longer than anticipated due to circumstances beyond the company’s control.”

The FCC shouldn’t give AT&T and FirstNet control of the 4.9 GHz band, Milwaukee County Executive David Crowley told the FCC in the latest filing on the contested band. Giving FirstNet control “would strip today’s 4.9 GHz public safety licensees’ right to expand their systems by forcing incumbent licensees to surrender the spectrum they are not using” and “runs counter to a 2023 FCC order and its commitment to locally controlled public safety in the 4.9 GHz band,” said a filing Wednesday in docket 07-100. It would also allow AT&T “to use the band for commercial purposes, which runs counter to the mission of this public safety band,” Crowley said.

Shure and the Aerospace & Flight Test Radio Coordinating Council (AFTRCC) notified the FCC they are making progress on technologies that support wireless microphone operations on a shared basis in the 1435-1525 MHz band “and the related continuing collaboration between Shure and AFTRCC in developing coordination and registration procedures.” They said discussions were “very productive” and “substantive.” The FCC’s Part 74 rules require protections for aeronautical mobile telemetry frequencies in the band, used for “flight testing of crewed and uncrewed military and civilian aircraft,” a filing posted Thursday in docket 14-166 said.

T-Mobile’s proposed $4.4 billion buy of UScellular would be credit positive “because it will expand T-Mobile's scale and provide it with potentially material synergies” and won’t “materially affect T-Mobile's credit metrics,” S&P Global Ratings said Wednesday. The agreement was announced Tuesday (see 2405280047). “T-Mobile estimates the deal will yield about $1 billion of annual run-rate cost and capital expenditure savings, which we view as achievable based on previous transactions,” S&P said. The firm warned that the expected $2.2 billion-$2.6 billion in integration expenses should be “modestly dilutive to the company's cash flow over the near term.”

Making money has to be the goal when providers expose their application programmable interfaces (APIs), experts said during a Mobile World Live webinar on Wednesday. Open APIs are a growing focus of carriers (see 2404160065) and of the GSMA (see 2402260054). “Monetization is really the end goal,” said Peter Jarich, head of GSMA Intelligence. Operators need to expose network capabilities in a consistent way, he said. Consistency is “particularly important” because that leads to interoperability, he said. That allows carriers to “monetize those network capabilities that they built out in a transparent way” so that developers don’t have to go to every operator and “figure out how to integrate with them” and “start from scratch with every single operator they want to work with,” he said. When APIs are exposed consistently, you get the scale that’s attractive to developers, Jarich said. The industry is seeing “traction” since GSMA launched its API Open Gateway initiative last year (see 2302270069), he said. Carriers responsible for nearly 70% of worldwide connections are focused on open APIs, he said. Security is a top concern of providers, and it’s not surprising that many open APIs are focused on security and anti-fraud efforts, Jarich said. GSMA surveys show that operators aren’t just joining the open gateway initiative but are exposing their APIs, he said. Providers are building out fiber and 5G networks against the backdrop of challenging economic conditions and shrinking profit margins, said Ana Redondo, product strategy lead in the Networks Division at telecom tech company Amdocs. “There’s very intense competition worldwide,” she said. “It isn’t an easy environment to operate in,” she said. Carriers are trying to reduce costs and grow core revenues where possible, she said. 5G hasn’t worked as well as carriers hoped, but fixed wireless access “has proven to be very successful,” she said. Open APIs can put carriers “in a far more competitive position,” she said. Carriers have a lot of assets they can monetize in the data that they have, their data centers and edge capacity. Carriers are asking how they can expose everything they do as APIs, she said. It’s a “fundamental shift,” but it puts providers “closer to how the cloud vendors work,” she said.
