Is 5G prone to interference?

However, it is expected that 5G signals may suffer interference . They can be easily blocked or diffused by physical object (buildings or atmospheric and environmental events) and will have a smaller footprint compared to other waves (2, 3 and 4G)[3]. Also, there might be problems with moving receivers/transmitters[4].

But at some airports where flights can still take off and land amid reduced visibility, some kinds of regional jets are nonetheless prohibited from flying because of concerns that radio signals from nearby 5G cell phone towers will interfere with radio altimeters on the airplanes .

Today, a majority of commercial 5G networks rely on spectrum in the 3.5 GHz range (3.3 GHz-4.2 GHz) .
