5G is a technology that is very short-range. If you have a concrete wall between the emitter and the receiver you will get a terrible connection. Maybe 30 mbps vs 500 mbps. Maybe 10 blocks away and you've already lost connection - unless there is another tower within a few blocks. So I don't think it would be feasible for big ISPs. maybe for some specific outdoor camps, yes. But it would require the cost of mainting infrastructure nearby all the RVs, including maintaining a clear view without physical obstructions.

5G doesn't have any bearing on the range, the frequency does -- 5G lowband will have about the same range is 4G. But to see the blazing multi gigabit/sec speeds, you'd need the high mmWave frequencies, which does limit the range,

Oh, did not know that. so 5G also includes a communication protocol ? E.g. could I make 5G work through 2.4 gHz (WiFi frequency, right ? ) and would it work well ? e.g. gigabit speeds thru 2.4 gHz ? I genuinely don't know, don't mean to make a stupid question.

kinda stupid question: (not meaning to sound as an asshole question) Isn't the mmWave part of 5G itself ? Or what would you define as 5G ?

3G/4G/5G are generations of protocols for cellular communication, they can run over many different physical frequencies.

Their standards committees agreed on certain bands of frequencies, some with more capacity than others.

I'm not an RF engineer, but given 5G can operate on frequencies higher and lower than 2.4Ghz, then I don't suppose there's any reason you couldn't if you were hacking up your own transmitters/receivers. A regular phone wouldn't, though, as they don't have 5G radios that can talk on those frequencies (or they've got hardware filters of some kind to ensure that they don't).

I think most of your questions are answered here:

As I understand it, 5G does everything 4G does, and adds new capabilities like mm-Wave.

Of course, all reports on it will emphasise the new stuff, so it's easy to get that impression.

I see 5g as the main connection while traveling, and starlink for back country. Is starlink latency low enough to connect to a bluejeans call w/ or w/o video?

starlink aims for about 20ms of latency - its good enough for video calls or gaming.
