the activation of AT&T and Verizon C-Band Frequency Means Improved 5G Mạng Network now available to millions of Americans. The long-anticipated rollout began on January 19, but on a note: Both companies temporarily pushed back plans for 5G networks near certain airports following criticism from the Civil Aviation Administration of Vietnam. Federal Aviation Administration and many airlines about interference from 5G repeaters affecting airlines’ radio altimeters.
AT&T and Verizon’s C-Band frequencies are mostly between 3.7 and 3.98 GHz; Airlines are concerned these mid-frequency waves could interfere with the radio altimeter that pilots use to know how far away the plane is from the ground. Recently statement from United Airlines says that, “when deployed next to a runway, 5G signals can interfere with critical safety equipment that pilots rely on for takeoff and landing in extreme weather conditions.”
Two days before 5G rollout, trade organization Airlines for Americas sent a letter, led by major airline CEOs to US Department of Transportation secretary Pete Buttigieg and others, urged them to intervene and stop 5G deployment within 2 miles of airports, which airlines other countries have requested in their own 5G rollout.
When AT&T and Verizon delayed 5G at airports for six months, the companies emphasized autonomy in their decisions. In a statement to WIRED, an AT&T spokesperson said: “In our sole discretion, we have voluntarily agreed to temporarily postpone the switching on of a limited number of towers around certain airport runways. As we continue to work with the airline industry and the FAA to provide more information on our 5G rollout, as they haven’t used it for two years they have had to responsibly plan for the rollout. this declaration. “
Verizon’s Similar comments The situation focuses on the company’s “voluntary decision” to halt rollout and blames the FAA and airlines for not being prepared to handle the 5G frequency, “even though it’s safe and fully functional.” enough in more than 40 other countries”.
For its part, the FAA is trying to figure out which radio altimeter will Not affected by the rollout of 5G. When the C-Band was released near airports, Boeing 787 operators were advised by the FAA to use extra precautions during storms. If necessary, the aircraft can be retrofitted with an improved altimeter to assist in landing in low visibility situations.
According to a statement from the FAA, “The agency has approved two models of radio altimeters to be installed on a variety of Boeing and Airbus aircraft. This combination of aircraft approvals and altimeters will open up runways at 48 of the 88 airports most directly impacted by 5G C-Band interference. The Boeing 777, which is widely used by both US and global airlines, is not yet on the FAA’s list of approved models.
President Joe Biden release a statement thanks AT&T and Verizon for the delay. It said, “This agreement will avoid disruptions that could severely impact passenger travel, freight operations and our economic recovery, while allowing more than 90% of wireless tower deployment goes according to schedule.”
