George Holmes, the chair and CEO of Resonant, a 5G industry player, told Barron’s that the difference between the U.S. and Europe stems from allocated frequencies for 5G, and their proximity to the defined band for altimeters.
Resonant is a Nasdaq-listed company that designs radio frequency filters, which are used to isolate signals from the right band while blocking unwanted noise from elsewhere in the radio spectrum. These filters are critical in 5G applications.
In the U.S., 5G is allocated to a range of between 3.7GHz and 3.98GHZ, which is closer to the 4.2GHz-4.4GHz frequency for altimeters than in Europe, which has allocated the 3.4GHz-3.8GHz range for 5G. Holmes said that in Europe altimeter filters will be better at stopping 5G signals, which will result in less potential interference.
“We are dealing with very low probabilities but extremely devastating consequences,” Holmes said. “We are still in the early stages of 5G deployments and usage, so this interference problem remains a potential for the future.”
“Longer term, this highlights the need for high-performance filters for all of the different technologies to co-exist above 3GHz,” he added.
For its part, the CTIA—a trade group representing the U.S. wireless communication industry—underscores that nearly 40 countries already use 5G in the region of the radio spectrum shared with altimeters, with no impact on aviation.
The CTIA cited the Australian Communications and Media Authority, which considers a 200MHz “guard band” protecting radar altimeters to be sufficient. When the FCC allocated space in the radio spectrum for 5G wireless services in early 2020, it left a 220MHz space between these services and the band for radar altimeters.
Divergent decisions among regulators in the European Union and U.S. could also be a matter of politics.
Jonathan Atkin, a managing director at RBC Capital Markets specializing in telecommunications, told Barron’s that the difference may be mostly due to interagency dynamics within the U.S. government that don’t apply in Europe.

5G has been a controversial topic for several years. Hard to know how to separate fact from fiction when so many reporting it have self-interests in it. Are we supposed to be excited, freaked out, or terrified?

Well, some have tried to raise the alarm about higher rates of cancer and other major health concerns so there's that.

I wondered about this as well. At least in terms of the effect on piloting aircraft. Was this discovered fairly recently?
For years, the aviation community has been raising red flags about 5G interference with aircraft safety instruments—concerns that have been ignored by the FCC and the telecom companies, creating the mess we’re in today. ~ ALPA President

We've known 5G was coming for a couple years, it seems like, and now it's an emergency. FAA, FCC, Verizon, ATT....wake up!
My understanding is that even though 5G is successfully used in Europe around airports
the radio frequencies are slightly different..
European 5G radio frequencies are at 3.4 to 3.8 GHZ
American frequencies are at 3.7 to 3.98 GHZ
The frequencies used by airplanes is 4.2 to 4.4 GHZ
The frequencies used by airplanes is slightly closer to the 5G frequencies used in the U.S. than in Europe. Of course, American carriers go to Europe, and I would hope they would be aware of the difference in case of erroneous readings from the altimeter.
