Cry babies. They should be blasting themselves for not testing the cr---y C-band before they bought it. To quote "Animal House", they ef..d up- they trusted the FCC. Same goes for Verizon.
AT&T adjusts 5G launch plans around airports, blasts FAA over delays

Maybe some tinfoil over the faa sensors will help the altimeter on the aircrafts. What do we need those for anyway now that 5g is here. It's most likely the airlines who are on the brink of bankruptcy who didn't upgrade their gear in anticipation of the roll out of 5g. If they upgrade the gear on planes we will no longer need anyone as 5g can do it all, isn't that what we were promised Mr. Stankey? Sold a bill of goods while customers are left holding the bag.
how do you propose they test the spectrum before it's allocated to them?
It's on the FCC. They sold AT&T and Verizon spectrum that is supposed to work, for consideration received. If that is not actually the case, the FCC owes Verizon and AT&T a refund.
pretty obvious the OP has zero clue how it works.
Actually you have no idea what you are taking about. Neither the FAA nor the airlines have shown any proof of interference. This is a knee jerk arm twisting reaction from the Biden administration.
