The auctioning of the C-band for 5G use has raised concerns in North America that signals could interfere with aircraft altimeter operations. 5GTW asked a filter engineer and a test expert if there’s a problem and how to fix it.
Signals from 5G towers that use the C-band will likely occur at the same time as those transmitted from an aircraft altimeter, though at different frequencies.

I’m going to put a report together, should be published on LinkedIn soon.
US has higher power, that’s the concern.
But FAS cleared 90% of commercial airplanes.
FAA not FAS.
