5G could Prompt Flight Diversions

The U.S. Federal Aviation Administration warned that interference from planned use of 5G wireless spectrum posed an air safety risk and could result in flight diversions.
The aviation industry and the FAA have raised concerns about potential interference of 5G with sensitive aircraft electronics like radio altimeters. AT&T and Verizon Communications in November agreed to delay the commercial launch of C-band wireless service until Jan. 5 after the FAA raised concerns.
