All this drama about 5G and aircraft. Japan solved the problem a year ago. It's only the USA that won't accept it, probably for financial reason.
Read this:-
We all or most of us got 5g in South Africa.
My internet is running on 5g.
...and have had 5g for just over 2yrs now. No issues in SA as far as I know.
So only airlines that fly international have replaced them. T-Mobile has 5G here in Oklahoma. I guess that means I won't have 5G near the airport.
@Lorajay IIUC, all US airports have 5G, planes with up-to-date altimeters have no 5G interference problems. Non US countries did not sell the 'close-to-5G' bandwidth frequencies, thus avoiding the problems altogether.
