The FCC Wireless Bureau sent letters Friday to seven providers reminding them of their buildout obligations under the agency's 3.45 GHz rules. The letters went to Columbia Capital, Cherry Wireless, Whitewater Wireless, Grain Capital, N Squared Wireless, Skylake Wireless and Blue Ridge Wireless. Companies that don’t meet the 2026 requirements face “significant regulatory consequences,” the bureau said.

The Safer Buildings Coalition (SBC) said Thursday that the record shows unanimous support for its July petition asking the FCC to launch a rulemaking on guidelines for getting consent from licensees to install signal boosters (see 2511130025).

Representatives of radio altimeter manufacturers met this week with FCC staff to explain recurring concerns with the agency's proposals to auction the upper C band. Commissioners unanimously approved an NPRM in November that asks about issues, including protections for the flight safety devices (see 2511200046). The meeting included staff from the Wireless Bureau and Office of Engineering and Technology, according to a filing posted Thursday in docket 25-59.

The FCC Public Safety Bureau said Thursday that June 12, 2028, is the deadline for commercial mobile service providers participating in the wireless emergency alert program to implement multilingual templates that alert originators “can choose to send during life-threatening emergencies.” The FCC recently published the rules in the Federal Register after a long delay (see 2512150044). It authorized the rules in October 2023 on a 5-0 vote (see 2310230031).

CTIA representatives met this week with an aide to FCC Chairman Brendan Carr and others at the FCC to raise concerns about satellite spectrum-sharing proposals before the agency (see 2508280006|). “CTIA highlighted the rapid growth in demand for full-power licensed terrestrial spectrum and reiterated the need for the Commission to continue its vital work of both expanding and protecting terrestrial wireless operations,” said a filing posted Thursday in docket 25-157.

U.S. Supreme Court justices could decide Jan. 9 whether to grant cert and potentially address a circuit split over fines that the FCC imposed on AT&T, Verizon and T-Mobile for violating the agency's data privacy rules (see 2512150027). That’s the date of the next conference for justices to decide which cases to hear. The data fine case, 25-567, was distributed for discussion then, the court said Tuesday.

The FCC Wireless Bureau on Tuesday delayed the deadline for reply comments on the preliminary eligible-areas map for the Alaska Connect Fund (see 2511190039) from Friday to Jan. 7. The change came after the agency released a revised version of the map to “address concerns and questions from stakeholders,” said a notice in docket 23-328.

The National Sheriffs’ Association asked the FCC to delay the deadline for comments on an NPRM on incarcerated people’s communications services rules (see 2512040036). “The comment deadline falls during one of the most significant holiday periods of the year, spanning Christmas, New Year’s, and the days immediately surrounding them,” the group said this week in docket 12-375. It added that it's surveying its membership and needs more time to get “a statistically significant sample size and to compile and analyze the resulting data.”

Neology, which provides a platform for tolling services that uses the 900 MHz band, filed a technical study at the FCC this week challenging arguments by NextNav in support of its proposal to use the spectrum for a “terrestrial complement” to GPS for positioning, navigation and timing (PNT).

T-Mobile maintains its fixed-wireless access leadership position, with a median download speed of 209.06 Mbps, “approximately double that” of AT&T’s median speed of 104.63 Mbps, Ookla said Monday. It found a “noticeable decline” in the download and upload speeds of T-Mobile, AT&T and Verizon during Q2 and Q3. That may be a “seasonal pattern,” since the firm said it detected similar declines last year. “It’s also possible that this may be an early indication that strong uptake in FWA is starting to impact performance.”
