Why was the deployment of 5G in the US delayed again?

2022 began and US airlines reached a new agreement to delay the implementation of 5G technology at airports.

With this, the telephone operators AT&T and Verizon will not be able to install them, at least, until January 19. This Wednesday, January 5, its application was scheduled.

President Joe Biden pointed out it’s a statement: “The agreement is a significant step in the right direction, and we are grateful to all parties for their cooperation and good faith.”

“This agreement ensures there will be no disruptions to air operations for the next two weeks and puts us on track to substantially reduce disruptions to air operations when AT&T and Verizon launch 5G on January 19.”

But what is the reason why many airports should not use 5G technology yet?

Reasons to stop 5G at US airports

In 2021, the Federal Aviation Administration (FAA) warned that some Airplanes would suffer interference in their radio altimeters due to this type of connectivity.

“These limitations could prevent the sending of flights to certain places with low visibility, and could also result in flight diversions,” said the FAA on December 8.

If airlines and pilots can demonstrate that their planes have 5G-protected altimeters, or that they will not be affected by interference, they can land in low visibility conditions. However, it always represents a significant risk.

The FAA explained that if 5G technology was used in 2019, 345 thousand passenger flights and 5,400 cargo flights would have suffered delays, diversions or cancellations.

What do companies say about it?

AT&T and Verizon reluctantly agreed to the new delay: Both companies have invested more than $ 68 billion in the new type of connectivity. At the time, they also offered to reduce the power of the 5G towers for six months.

This week, AT&T said: “We know that aviation security and 5G can coexist, and we are convinced that by seeking collaboration and technical evaluations we will solve the problems.”

The other possible solution offered, this time by technical experts, is developing a filter band for altimeters. But according to the Radio Technical Commission for Aeronautics, this would take years to receive certification, in addition to modernizing the planes.
