It is for this reason that the US Federal Aviation Administration raised concerns.Ĭountries around the world have started to roll out 5G technology. If this happens, even for a few seconds, it could mean the pilot doesn’t receive the correct information during landing. That is, people using 5G on their phones could inadvertently distort or damage the radio altimeter’s signal. The concern is that, due to the narrow gap between the frequencies of the 5G and the radio altimeters, the radio waves from 5G towers near airports could cause interference. Why 5G conspiracy theories prosper during the coronavirus pandemic Pilots rely on radio altimeters to land the plane safely, particularly when visibility is poor, for example, when the airport is surrounded by high mountains or when conditions are foggy. An important piece of an aircraft’s equipment, called a radio altimeter, operates on C-band frequencies between 4.2-4.4GHz. These frequencies are adjacent to those used by modern aircraft to measure altitude. To ensure high speeds with the widest possible coverage, AT&T and Verizon had planned to generate 5G internet using something called C-band frequencies, a type of radio frequencies (or radio waves) between 3.7 and 3.98 gigahertz (GHz).
