I'd guess that should be enough for any sane person to question the praisee's real motivation (in this case or anu other)
A growing inter-agency row over America's use of particular radio frequency bands for 5G phones has burst into the open – with a senior US Department of Commerce adviser fingered as the main source of problems. In a letter [PDF] to Commerce Secretary Wilbur Ross this week, Senator Ron Johnson (R-WI) broke an unwritten …
The dude is being paid by small telcos to block 5G because they can't compete with established big telcos when building out the system
I can't work out from the story if he is in favor or against the question.
As a good republican he must be against the intrusive communist census
But as a good Trumpian he is presumably in favor of having all the foreigners on a list (and preferably wearing some sort of badge on their clothing.)
Or will it all be a dream in the shower ?
The 24 GHz is only good for point to point links, sports stadiums, auditoriums and open plan offices.
My thoughts entirely. Even on point to point links precipitation attenuation can be rather severe so the link budget has to include a (potentially very) large fade margin; with fixed links a lot of that margin can be obtained by using large parabolic aerials with high gain, but those are not really practical for portable use*.
It also occurs to me that making a handset with enough transmitter power at 24 GHz is going to be a significant challenge; I would expect it to guzzle battery power at a frightening rate.
* This is called understatement.
I agree as well. When I first underwent certification training for line of equipment, I was given the rule of thumb; the higher the frequency, the more it acts like light. at the time we were talking 2.4 and 5.8 and that 5.8 would give near line of site, because it would reflect off of things while 2.4 was a lower frequency and it needed line of site. Also part of that rule of thumb is that the signals wouldn't penetrate solid water. A rainstorm is solid water as is a tree. 24 GHz would be good for setting up short hop meshes which, I think, is the idea.
Hi-fi audio (venue quality, not highend) requres about 100 kbps. And you're talking about a broadcast, not lots of unicasts. That can be done on low spectrum, narrow channels. It needs 24 GHz the same way you need a fleet of Peterbilt trucks to drive your kid to school in the morning, and school is only 200 meters away.

So ... you'll go to a live performance, and listen to it on your phone? And watch it on the phone too, I expect.
Basically like watching and listening from home, except more expensive, less comfortable, and less convenient. Right.
I suppose there's some use for 5G that isn't mind-bogglingly stupid, but I haven't heard of it yet.
It seems to me the biggest plus of 5G won't be for mobile (at least in the US), but data distribution for the "last mile" to homes in subdivisions that are not economical to install fiber into. Put up a roof antenna for 5G, and you get high speeds without the cost of that low return infrastructure.
The article mixes up two unrelated entities called "Comptel".
The one the US federal employee covered in the article used to work for was a US competitive carriers lobbying association and a moment's googling allowed me to discover it is now called Incompas.
The one Nokia acquired was a specialist telecoms software company headquartered in Finland (but operating worldwide). It is now fully part of Nokia.
