"FAA issues 5G warning for Boeing 737s but says practical effects are limited
The Federal Aviation Administration has warned that 5G wireless operations can interfere with radio altimeters in Boeing 737s, impeding a crew's ability to safely fly or land, but FAA officials stressed the issue poses little practical effect for airlines.
Despite dire-sounding language in the FAA airworthiness directive issued on Wednesday about potential effects on 737 landings, it does not apply to aircraft flying into areas where the 5G environment has been rendered safe for aviation, which the FAA said includes nearly all airports."

"Europe rolled out 5G without hurting aviation. Here's how
...
Mobile phone companies in the United States are rolling out 5G service in a spectrum of radio waves with frequencies between 3.7 and 3.98 GHz. The companies paid the US government $81 billion in 2021 for the right to use those frequencies, known as the C-Band. But in Europe, 5G services use the slower 3.4 to 3.8 GHz range of spectrum.
The aviation industry is worried that US 5G service is too close to the spectrum used by radar altimeters, which is between 4.2 and 4.4 GHz. Europe does not face the same risk, according to the industry, because there is a much larger buffer between the spectrum used by radar altimeters and 5G.
