FAA Warns of Aviation Safety Risks Without US Mandate On 5G Limits

The Federal Aviation Administration (FAA) wants the U.S. telecommunications regulatory agency to ensure a delay in some 5G C-Band transmissions from smaller operators. Reuters reports: Acting FAA Administrator Billy Nolen said the agency wants the Federal Communications Commission (FCC) to mandate voluntary mitigations that AT&T and Verizon agreed to earlier this year mandated for 19 smaller telecoms and other spectrum holders. In a previously unreported letter dated Friday, Nolen cited industry data established "aviation safety would be compromised if the U.S. government does not codify certain additional operating limits in the 5G C-Band environment." Concerns that the 5G service could interfere with airplane altimeters, which give data on a plane's height above the ground and are crucial for bad-weather landing, led to disruptions at some U.S. airports earlier this year. Nolen's letter warns that without the FCC mandating the mitigations "the FAA would be forced to take immediate steps to ensure the safety of the traveling public, raising the likelihood of flight disruptions across the United States."
