Telecom operators AT&T and Verizon are reviewing the request of US authorities as the authority have asked the companies to delay the rollout of 5G networks. The rollout has already been postponed due to the uncertainty about interference with safety equipment. US authorities have requested to delay it further.
Aerospace giant Airbus and Boeing have raised their concerns about the network’s interference with the device’s planes. This is why the rollout of the network has been postponed till January 5.
Pete Buttigieg, the US Transportation Secretary and Steve Dickson, the head of the Federal Aviation Administration have sent a letter to AT&T and Verizon and inquired about the latest delay.
In the letter, the govt asked the companies to delay further the commercial C-Band service. In the letter, the govt also clarified it that the service of 5G network will start in January only. The authority is giving priority to certain airports.
Radio altimeters of airplane and 5G have same frequency
Authorities said it is to protect the flight’s safety. Verizon and AT&T have used 3.7-3.8 GHz frequency bands after they have got their license. But Airbus and Boeing have raised their concerns about the network’s interference with airplanes’ radio altimeters. The radio altimeters of airplanes also have the same frequencies.
The French authorities suggested that mobile phones with 5G should be switched off on plane. They think this must conclude the conflict between 5G networks and aircraft. Experts think interference of 5G network with radio altimeter of airplanes can cause “critical” errors while landing.
