"AT&T And Verizon Will Delay 5G Expansion Over Aircraft Interference Concerns"

AT&T and Verizon won't start rolling out their C-band 5G service on January 5th like they originally planned. Instead, they have agreed to comply with a request from the Federal Aviation Administration and the Transportation Department to push back their 5G expansion by two more weeks. Authorities asked the companies for extra time to investigate concerns regarding possible interference with aircraft systems and electronics. Airlines and aircraft manufacturers are worried that the new frequencies are too close to those used by airplanes' radar altimeter, which provides data on the distance between the plane and the ground. Interferences with the airplane's radar altimeter could lead to unsafe landings. Wireless industry giants argue, however, that the C-band service's powers are low enough and that the gap in frequencies is large enough to prevent interference.
