Altimeter Band : 4.2Ghz - 4.4Ghz
VZ and AT agreed (long ago) to reduce power and stay inside 3.7Ghz -
3.98Ghz once the full deployment was done, staying 200MHz away from
altimeters.
In Japan, they have been running 5G for over a year now up to 4,1Ghz, and
restarting again at 4.5Ghz. Only 100MHz

It's also relevant that the spectrum surrounding the 4.2-4.4 range has not
been an empty desert. It has been used for satellite downlink since the 60s
I think?
Yes, there are surely tons of differences in RF characteristics between the
two. But let's be honest. Analysis would have been done
Being a former satellite downlink/uplink operator I loosely kept up with this
and had some involvement.
The satellite vendors moved frequencies on some of their customers to make way.
I forget the full economics and seem to remember one could get reimbursed from
the FCC for the change.

Scott - a side note to clarify things...
The 737 Max8 problem was NOT due to lack of testing or non-incremental
changes. The system was well tested and put through it's paces. It was
a lack of proper pilot training in the aircraft and its systems and some
carriers choosing to NOT purchase

aircraft with the instrument landing system transmitters.
