 the US minister of transportation one Buttigieg was multitasking between breastfeeding baby's and doing that transportation stuff
so forgot about 5G and airport 5G microwave interference with aircraft altimeters. a US government cockup or blunder of the first order.

Except that Buttigieg has been US Secretary of Transportation for less than a year, and 5G has been in the works for much longer. Look to the previous administration and its expulsion of competent staff who were replaced by sycophants and stooges.

I mean, the technical improvements that allow serving more data to more people faster are pretty much justification enough?  Certainly if you look at mobile data usage trends over the past 10 years and projections on demand for the next 5 years, 5G looks pretty desirable.  Certainly some people will claim that "it's all cat pictures and tiktoks so we shouldn't be enabling increased usage", but who the fuck are they to decide what usage (and always by implication which people) are important?


--- Quote ---On the professional side every waste-of-space manager in telecoms from the boards of Fortune 500 companies down to the lowest line manager wants '5G' on their CV/resumé and will make decisions to facilitate that regardless of the merits of 5G itself.

That is true of literally everything, not even just in technology.  People who aren't directly involved see something they hear will be important and they want to get in on it.  It's as annoying as it is predictable, but it isn't any sort of reason to be upset about 5G.  It's just a fact of being human.  But with or without the hangers-on, the case for 5G is pretty clear, and the people actually working on it understand that.

Go back and read the whole thing again, I think you have a comprehension problem. I never said we shouldn't have 5G, I never said I was "upset about 5G", all I said was "Truthfully I don't think I could explain why 5G is a good idea/necessary.". You're arguing against points I didn't make.

.  IoT and IIoT,

.  require a lot
.  but really, a lot
.  of data
.  and speed.

In the 1990s you do not have any of those, so it's understandable 5G seems unnecessary

Thing is, I think for most people, they will not see the advertised significant speed improvement.  It has problem penetrating walls,  windows and even mere tree leaf.  So you are reduced to basically needing line-of-sight to the antenna.

According to talkingpointz.com which pop up as first on Google Search for "5g cannot penetrate windows":

This shows the REDUCTION of in-building coverage at the 5GHz frequency. The diagram is non-linear so you are looking at something like an 80%~90% reduction in in-building coverage.

The author of the chart correctly points out that cellular 5G coverage is 100x worse on 95% of typical Cellular 5G frequencies than today’s 3G/4G frequencies.

The other thing to pick out is that 600 MHz in-building coverage is vastly superior to the more common 1~2 GHz frequencies most 3G and 4G networks are built on. T-Mobile has been buying and deploying 600 MHz left and right because they know it is the best way to have “coverage everywhere” (Both inside buildings and throughout vast swaths of open land.)

Where cellular 5G naming gets so confusing is that it is widely associated with frequencies above 2.1 GHz and it is being billed as faster with promos touting GB speeds. The public is being advertised into thinking that cellular 5G is all about speed. This is true in that cellular 5G unlocks higher frequencies which can yield high speeds at very close distances.

But cellular 5G is much more about managing spectrum efficiently. One of the most important cellular 5G features is the ability to have overlapping cells. A carrier would have a 600 MHz cell that provides far and everywhere coverage in a large area, up to a 30 mile radius. Then, they would deploy 850 MHz, 950 MHz, and 2100 MHz to offload the 600 MHz cell. Finally, higher frequencies such as 5 GHz would be deployed in stadiums and concert venues where there are a lot of people very close to the tower. Users would be routed to the highest frequency that provides acceptable service. Thus, 600 MHz can be used to “fill in the gaps” and 5 GHz can be used to “fill in the gasps” with higher speed and bandwidth.

So except for the limited few, they will be seeing 3G/4G/LTE probably for much of the life of "5G" deployment.  The improved efficiency is a good thing.  It helps hold cost down for the carriers and some saving would be passed along to the customers - or at least price increase will be tempered somewhat.

Halcyon:
It's not unlike any other technology that gets improved over time.

Faster speeds, better (more efficient) use of the radio spectrum, support for more devices on a given chunk of air, better encryption, more features etc...

It's no different to why things like WiFi or televisions have evolved over time.
