5G Communication Technology – Do They Interfere with Flight Communication Signals

Several airlines have cancelled flights to the United States as a result of the country's 5G rollout, claiming that 5G signals could interfere with critical safety equipment such as the altimeter, which pilots rely on for takeoff and altitude readings. The proposed C-band spectrum extends from 3.7 to 3.98 gigahertz whereas the aviation altimeters use the 4.2 to 4.4 gigahertz. This narrow gap between the frequencies isn't nearly enough to ensure that a mobile carrier signal isn't mixed with or corrupted by an altimeter signal. Though the chance of an in-flight issue due to 5G interference may be low, it is important to treat any potential dangers seriously because it is about human safety. In this paper the measures taken by various countries to avoid this signal interference is discussed in detail. Also the possible solutions for communication and aviation sectors to avoid signal interference are discussed.
