T-Mobile asked the U.S. Court of Appeals for the D.C. Circuit to act on its petition for rehearing of a decision by the court upholding an $80 million data breach fine by the FCC (see 2508150014). T-Mobile was also fined $12.2 million for actions by Sprint, which it later acquired. The FCC has asked the court to hold off on a decision while the U.S. Supreme Court decides whether to hear appeals by Verizon and AT&T challenging similar fines (see 2511170035).

The FCC's order to overturn a January ruling and NPRM addressing the Salt Typhoon cyberattacks, approved 2-1 last week (see 2511200047), benefits WISPA members, the group said Tuesday in an emailed statement. “This is an important development that removes an unnecessary regulatory burden from all commercial broadband providers irrespective of the technology you use to serve your communities.”

NextNav said a new technical analysis demonstrates that 5G-based 3D positioning, navigation and timing operations can coexist with RAIN systems in the lower 900 MHz band, with “no operational impact … in typical real-world deployments.” For any measurable change to happen, “an implausibly strong 5G signal would need to align with multiple additional simultaneous conditions that rarely align in the real world,” said a filing posted Tuesday in docket 24-240.

AT&T told the DOJ that it needs to buy “unused 3.45 GHz and underutilized 600 MHz Spectrum” from EchoStar to compete in an increasingly competitive wireless market, according to documents filed at the FCC. AT&T's arguments to DOJ were submitted to the FCC at commission staff’s request and posted Tuesday in docket 25-303. The company recently said it has already started to deploy the 3.45 GHz licenses it bought from EchoStar (see 2511170023), adding coverage to nearly 23,000 cellsites in a matter of weeks.

Anuvu is supposed to show how the C-band Relocation Payment Clearinghouse was wrong in finding that the company can't get reimbursed for its German facility modifications, but it hasn't made the case of where the clearinghouse erred, the FCC Enforcement Bureau said in a brief posted Monday (docket 21-333). The bureau said much of Anuvu's argument revolves around one footnote in the FCC's C-band clearing order, and the agency can't make broad policy announcements in footnotes. But the C-band clearing order repeatedly makes clear that reimbursement of transition costs is only for those incurred within the U.S., the bureau said.
