The U.S. Federal Aviation Administration (FAA) updated information Thursday, maintaining that U.S. 5G deployment will require the FAA to impose flight restrictions on flight operations using certain types of safety equipment that will perform in proximity to the 5G networks. AT&T and Verizon agreed to delay the use of C-Band spectrum until Jan. 19, a move that was endorsed by the White House. This extension would give the FAA more time to study and evaluate how to minimize the disruption to radar altimeters, while preparing airline companies for any changes. The telecom companies, which won access to almost all the C-Band spectrum in an $80-billion auction, had earlier agreed to adopt 5G deployment with similar precautions as that of France. The crux of the issue lies in the fact that radar altimeters, an important piece of safety equipment used in aircraft, use frequencies close to C-band. 5G services use C-band …
