It needs to work backwards, much like Video Codec and ask what do the stakeholders really want or need? We are closing in to rolling out the last / final phase of 5G. And yet none of the Massive MIMO on FDD is happening. We are still stuck on 32T32R, hardly that impressive considering we have that in LTE already. Not to mention the insane complexity increase from 4G to 5G. And judging from the previews of 6G that see…

I think it’s also because the best frequencies are already occupied by 2g/3g and 4g so it’s hard to provide good 5g coverage over large areas.

'best' is relative here; lower bands travel further, which is great for maximizing coverage footprint, but not great for high-density. Each node can only handle so much traffic, and you can pack them in more densely with short-range spectrum. mmWave really is the best frequency for very high density, high capacity networks, but the bottleneck is you have to deploy all the extra nodes to get the coverage.

Something I've noticed is that a phone is actually usable at a stadium or concert when 3g or 4g felt essentially useless at that density.

Net neutrality would have prevented this kind of pay to win

People still believe this? Google pays their ISP. I pay my ISP. Google does not pay my ISP. Why is my ISP's response to the amount of traffic I use demanding to bill someone other than me?

To be clear, Google was doing this out of self-interest. Paying user ISPs for access to those users is not a cost they want to pay. But it's the same as any other protection racket. A local shopkeeper has personal reasons to not want to pay off the mob, but that doesn't mean their position is wrong.

Most of what passes for 5G in the US is the same old but full duplex with wider channels. Calling that 5G obscures the fact that millimeter wave 5G standalone is a totally different beast, and a huge network engineering challenge. It may seem bureaucratic to regulate what people can call 5G, but US consumers get ripped off thinking they're on an advanced network when in fact you could call it the long-term evolution…

My phone clearly shows me when I'm on 5G vs 5G mmWave.

5G mm is vaporware. Virtually no one uses it (especially globally) and it is expected to be stripped out within a generation or two.

No it is not. 2G->3G->4G->5G refer to real changes in technology and system architecture, as detailed in the Wikipedia page you linked to. 3GPP releases are more fine-grained than that. E.g. rel. 99 introduced 3G/WCDMA, rel. 8 introduced 4G/LTE, etc. Other releases only add features. In the industry Gs are used all the time to refer to the technology/architecture, then releases are used to refer to specific features,…

Tell that to the cellular industry marketing people who decided to put "4.5G" on things. Also not everything that is marketed "5G" is equal in capability, there's a myriad of different bands in different regulatory regimes in the world, some of which go through material like brick/concrete much better than others. You'll see "5G" connections that have speed tests in an urban area that top out at 50 Mbps downstream an…

"G" is becoming about as useful for identifying differences in mobile performance as "X" was for identifying CDROM speeds. As soon as marketers realized they could put any number they wanted before the X and outcompete their competitors, the number became useless.

I thought that's why many large venues offer free WiFi.

5G outperforms wifi in crowded situations. With wifi you get increasing collisions and backoff intervals until everything stalls; with 5G you just get less bandwidth (time sliced) but no collisions, and its frequency spectrum is free of interference.
