5G technology

is under fire from the Federal Aviation Administration in the United States. The authority in charge of managing air transport in the country has just announced a new safety rule. It prohibits pilots from using automatic landing and other flight assistance systems at low altitude. It believes that 5G signals could interfere with the instruments that calculate the aircraft’s distance from the ground.

Interference with some landing systems?

For the FAA, 5G would interfere with the radio altimeters used on flights with low visibility conditions. Radio altimeters allow safe landings in this configuration.

But the FAA believes that 5G could cause erroneous data readings, making the flight unsafe. In particular, the new technology would affect certain radio frequencies. That’s because the waves used by 5G cover a part of the radio frequency spectrum called the C-band, which is adjacent to the waves used by radio altimeters to measure an aircraft’s altitude.

According to the FAA, the rule would affect more than 6,800 U.S. aircraft, more than 1,800 helicopters and dozens of aircraft manufacturers.

The FAA ‘s injunction is of an emergency nature. ” A dangerous condition exists that requires immediate adoption of this [order] without providing an opportunity for public comment prior to adoption,” the agency said. ” The FAA has determined that the risk to the flying public warrants waiving notice and comment prior to adoption of this rule.

The FAA plans to also publish a list of airports most likely to be affected by 5G technology. This could result in some airports banning the use of 5G in and around their territory.

Civil Aviation Authority says it has been working for many months with telecom operators involved

in 5G technology.

The FAA says it is working closely with the Federal Communications Commission and wireless carriers. It believes it has made progress toward a safe implementation of 5G expansion. According to the FAA, ” we are confident that with continued collaboration, we will achieve this common goal of safe coexistence


The concern around the FAA has already resulted in a delay in the rollout of 5G in the US. Originally scheduled for December 5, 5G will become effective on January 5

next year after the industry agreed to a delay.

The association representing the wireless industry, CTIA, opposes the FAA’s decision. ” Any delay in enabling this technology risks America’s competitiveness. It jeopardizes our ability to provide global leadership in 5G,” the association says.

According to the CTIA, C-band spectrum already represents the backbone of 5G networks worldwide. Nearly 40 countries are using this spectrum, many of them for nearly three years. And with no real danger to aviation, it believes.
