The F.A.A. also argues that it was excluded from decisions about 5G. In 2020, the F.A.A. administrator, Stephen Dixon, prepared a letter to ... the F.C.C., expressing concerns about 5G interference, but the letter was not passed along by ... the acting director of the Commerce Department’s National Telecommunications and Information Administration.Larry Kudlow, who headed President Donald Trump’s National Economic Council, even bragged about blowing off the F.A.A., saying on his Fox Business show, “We ignored them because the science said don’t worry about it.” He added later, “We actually fought the F.A.A. and we won.”It appears now that the Trump administration won the battle but not the war. One result of the extended conflict between the F.C.C. and the F.A.A. is that even now, nearly a year after the spectrum for 5G was auctioned off, the F.A.A. is still at the stage of information-gathering as it moves toward eventually issuing new requirements for radar altimeters. It is likely to take five years for all altimeters to be upgraded.

So typically government. How many years ago did they auction off the spectrum? Duh.
That said, I favor 5G over the airlines. It's more important. Sorry, but we've morphed from transportation to communication. Think about it. It's a continuum. Albeit moving goods and moving busses of data.
I also don't believe the airlines. They're not having issues overseas AND these are the peeps who lied to us for what? 10? 15? years over cellphones in planes.
Nah, roll it out completely. It's more important.
and so it goes,
peace and wear the damn mask,
How 5G Clashed With an Aviation Device Invented in the 1920s
The point here is that the FCC certainly knew well before the 5G C-Band was auctioned/assigned to the telcos that some of those frequencies were already in use for aviation purposes. That's their job. It's incomprehensible to me how all of this was allowed to happen, presumably without coordination between the FCC and the FAA.
Evidently this was dealt with properly in at least some European countries, since we're being told that France, for example, is using 5G near airports with no problems.
Something is really smelly here.
US 5G C-band frequencies (T, VZ) 3.70-3.98 GHz
T-Mobile 5G frequency (band 41) 2.5 GHz
Other frequencies are in use too, but the above are relevant for airplane instrumentations that have used 4+ GHz for decades. And only the US 5G C-band is near those, NOT T-Mobile 5G, nor European 5G.
When we determined exactly what frequencies were in conflict we notified the telcos, who would then discontinue use of that particular frequency at that particular location.
So the potential for this sort of thing is well known to the FCC. Again, I cannot begin to fathom how this was allowed to happen with respect to the radar altimeters. 3.98 ghz and 4+ ghz are simply too close for comfort.
It shows a zero visibility automated landing at the Milan International airport, and it's well worth a watch. At the beginning it seems as if there's no motion at all... be patient.
If you happened to be flying on this aircraft would you be concerned that the radio altimeters were working correctly?
‘It Wasn’t Our Finest Hour’
Kudlow was a college classmate of mine, Porsche-driving (iirc) SDS leader
I'm not able to access the NYT article. What is the Kudlow reference to/for SDS?
From a generational (age group) knowledge/view, my first thought when I see the letters, SDS, is: Students for a Democratic Society (radical political organization of the 1960s).
They held their first meeting in 1960 on the University of Michigan campus at Ann Arbor.
--- The Weatherman Group (formed in 1969)
The Weatherman Group was an anti-war and anti-government group within the Students for a Democratic Society that became popular in the 1960s for speaking out against America's role in the Vietnam War. The group was mainly made up of affluent college students.
Free Dictionary terms for SDS
The NYT article also mentions that there are technological fixes for radio interference by using various types of filters, and/or by redesign of the radio altimeters themselves. This is true to a point, the but installation of filters in the affected aircraft may very well introduce other problems, and of course modifying or replacing the altimeters will be a very costly procedure likely involving significant aircraft downtime. As usual, money is involved, so we have potential winners and losers.
It's quite possible that rather than engage in an unproductive inter-agency fight the FAA elected to let the airlines themselves carry the fight to the FCC. These people are masters at this sort of thing. This is what I meant in my post up above where I said that "something is really smelly here.".
Thank you. And yes, Kudlow having some time with the SDS is of no consequence to the subject.
Especially since DSP can indeed readily solve things:
“This is very, very easily solved technically,” said Theodore Rappaport, a developer of 5G technology who is a professor at New York University’s Tandon School of Engineering. “It’s frustrating as an engineer” to see the old technology still in use, he said. The F.A.A.’s argument is that it couldn’t issue a new standard for radar altimeters without knowing in detail the design of the 5G equipment. Etc.
Kudlow's comical college history was on point for anyone familiar with his years of divisive rightwing free-market blathering in economics and policy as Trump's NEC head, and before --- here crowing about beating the gov agency crucially charged w air safety. Seriously.
A commenter makes the point plainly but without any classmate jokes about a former Porsche-driving SDS leader who (sort of) reversed course in life:
... Ajit Pai [FCC], Larry Kudlow, and the rest of the clown car went to Washington to let industry, in this case the communications industry, do anything they pleased. Maybe that was based on their childlike faith that markets cure all ills and government can only do wrong. But the result was that administrative agencies whose job was nonprofit things like, you know, not crashing airplanes had no voice in the Trump government, and businesses such as telecom has no one watching who cared about consequences. The result was predictable. The wonder is that no one has died as a result. Yet.
"the acting director of the Commerce Department’s National Telecommunications and Information Administration"
I believe I read in a different news story that Trump had never appointed a Director of NTIA. So nobody was really in charge.
