Hello everyone! Lately the topic of 5G networks turning on across the country has been relevant in the news. Specifically, the relation between 5G and aviation. There may be some confusion so hopefully we can help alleviate any concerns.
5G is the fifth generation of cellular data/technology. It uses c- band radio frequencies, which is described as all frequencies ranging from 4-8 gigahertz. The concern for aviators however, is the potential effects it may have to on board radio operated systems. 5G uses a variety of frequency ranges though. Some towers may emit 600-900 megahertz while others are as high as 24-47 gigahertz. Most towers will be using a mix of those frequencies. The towers can also be turned downed or turned off near certain locations such as airports.
The concern from the Federal Aviation Administration is that the higher frequency radio waves are uncomfortably close to the same frequencies used on aircraft. The effect it has is primarily pertaining to radio systems such as radio altimeters, which may cause problems for low visibility approaches. Autolands, HUD usage, or any other systems reliant on radio altimeters could potentially be affected as well.
The solution? Well, so far there isn’t an overly huge concern for safety, as there hasn’t been any major incidents involving aircraft and 5G. But there is enough to make the heavily regulated FAA get involved. As of today, there are fifty airports in the U.S. with a “5G buffer.” This is described as an area surrounding these airports where the 5G transmitters while be turned off. The buffer zones apply within the last twenty seconds of flying time in all directions of the airport. This will be in effect for the next six months. Both Kansas City International Airport and St. Louis Lambert International Airport are on the list of fifty.
As far as Midwest National Air Center, no information has yet been relayed to indicate a problem with 5G altering normal flight operations. As always though, we will try our best to stay safe and informed on any new information as it arrives.
