The problem of airline companies suspending flights to American airspace has been exacerbated by the fifth generation networks.
The story began when the US Federal Aviation Administration warned of the dangers of the fifth generation network to aircraft safety, as the danger lies in the interference of the signals of these networks with sensitive electronic devices of the aircraft.
For example, interference may occur between signals 5G networks with plane altimeters off the earth’s surface.
The carriers Verizon and AT&T, which are starting to operate fifth-generation services today in America, say that the 5G service has been operated in 40 countries without problems for the aviation sector.
So why did the problem arise in America and not in Europe, for example?
The problem arose because the frequency range of the fifth generation networks in America is between 3.7 to 3.98 GHz, while the frequency range for aircraft altimeters ranges between 4.2 to 4.4 GHz, meaning that the range is very close, while in Europe the range ranges between 3.4 to 3.8 GHz, i.e. It is relatively remote and does not pose a threat to aircraft radar when taking off and landing.
Although AT&T and Verizon announced that they would delay operating 5G towers near airports to avoid security concerns, the concerns prompted airlines to cancel their flights pending safety assurances from the Federal Aviation Administration.
