AT&T and Verizon Communications have agreed to temporarily defer turning on some 5G telecom towers near key airports to avert a significant disruption to U.S. flights, Reuters news report said.
US President Joe Biden welcome the agreement, saying it “will avoid potentially devastating disruptions to passenger travel, cargo operations, and our economic recovery, while allowing more than 90 percent of wireless tower deployment to occur as scheduled.”
Airlines and the Federal Aviation Administration warned that new restrictions as a result of 5G service, which Verizon and AT&T are to launch on Wednesday, would still prompt some flight disruptions. Delta Air Lines said while the wireless moves were a positive development, some flight restrictions may remain.
The FAA has warned that 5G wireless interference could affect sensitive airplane instruments such as radio altimeters and significantly hamper low-visibility operations.
The FAA said it anticipated there will be some impacts due to the limitations of some radio altimeters.
Verizon will temporarily not turn on about 500 towers near airports, or less than 10 percent of their planned deployment.
Both Verizon and AT&T will launch 5G elsewhere in the country.
Federal Communications Commission Chair Jessica Rosenworcel said in a statement that the FAA has a process in place to assess altimeter performance in the 5G environment and resolve any remaining concerns. It is essential that the FAA now complete this process with both care and speed.
Airlines for America, a passenger and cargo trade group, said the pause provides the opportunity to ensure all stakeholders, consumers and the U.S. economy are served in the long run.
This is the third time that AT&T and Verizon agreed to delay deployment of the new C-Band 5G wireless service. The companies in November postponed deployment by 30 days until Jan. 5, and then agreed to delay deployment until Jan. 19.
Nearly all but a handful of the impacted sites are Verizon towers, officials said.
Still the FAA and airlines must grapple with how to resolve the concerns permanently — especially since AT&T and Verizon earlier agreed to take some measures to reduce interference for six months.
Despite the agreement, major foreign carriers including Air India and Japan’s biggest airline, ANA Holdings, said they had canceled some U.S.-bound flights because of possible 5G interference.
ANA said on its website it had canceled some Boeing 777 flights after Boeing announced flight restrictions on all airlines operating the Boeing 777 aircraft.
Airlines are likely to cancel some additional flights in the coming hours as they wait for formal guidance from the FAA on the announcements from Verizon and AT&T. They warned Monday of catastrophic impacts. Airlines had raised concerns that the issue could prevent them from flying Boeing 777s and other widebody jets to many key airports.
The airlines asked that 5G be implemented everywhere in the country except within the approximate 2 miles (3.2 km) of airport runways at some key airports.
Verizon’s 5G network rollout plan is more aggressive than AT&T’s. AT&T and Verizon won significant C-Band spectrum in an $80 billion auction last year.
Verizon Chief Executive Hans Vestberg told employees on Jan. 4 the carrier saw no aviation safety issue with 5G and had resisted prior delays.
