There is a fascinating dispute unfolding between the wireless
communications industry and the aviation industry, or rather, a
dispute between their respective regulators, the Federal
Communications Commission (FCC) and the Federal Aviation
Administration (FAA). The dispute revolves around the wireless
carriers' use of C-Band spectrum to deliver 5G and the aviation
industry's use of nearby spectrum to control aircraft.

Listen to this 12-minute podcast as Steve Rosen, a Partner at LB3,
David Lee, TC2's Technology Director, and Joe Schmidt explain this
technical and legal conundrum and why it will be a regulatory and
economic train wreck if the dispute doesn't get sorted.

A good presentation of the details, most of which have not been adequately reported in the popular or even the technical press:

Ok, I see the issue.

My question is why did they wait until 5G is about to be deployed
rather than speaking up well before now?

Because neither the FAA nor the FCC have many technical experts left. So
it takes a long, long time for technical issues to trickle up from the few
technical people through all the lawyers up to the top.

European countries dealt with this quickly and efficiently.

And the honest truth is that for modern radar altimeters this isn't a
problem. But there are plenty of planes out there flying whose radar
altimeter receiver is just a horn and a diode detector. They were designed
that way because there wasn't any use of adjacent bands so nobody bothered
putting money and effort into making them any better.
