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…

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 (see what I did there?) of the existing network.

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.

3G has been shut down in several countries to free up frequencies. 2G was also shut down in several countries, it seems to be still up in most european countries with shut downs being scheduled in the next few years up to 2030.

2G is hard to shut down, because it just works, and many of the core services and old phones rely on it. It will survive 5G, 6G, 7G an other Gs.

Note that "G" generally is a marketing term for consumers, the actual tech is 3GPP rev-whatever https://en.wikipedia.org/wiki/3GPP Like 3GPP release 15 or 16 is what we currently know as a lot of in production LTE/LTE-Advanced stuff.

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, though generally noone supports all the features of a release.

sure but is anyone deploying mmwave outside of maybe sports stadiums? I'm not exactly going to get it on my commuter train or at work.

4G used clever ideas to get much better practical spectrum efficiency than people thought was possible... At the cost of very expensive infrastructure. The biggest selling point to carriers was standalone 5G networks that were cheaper to build but paradoxically carriers are prone to frame 5G as a feature customers pay more for.

The area where wireless networks fall short is coverage. Obviously many homes and businesses are difficult to cover with wireless technology. Also many "IoT" and public service situations need wide coverage, and a network that works in 92% of places is "close but not cigar." There are few obvious answers rather than "lots of fiber and very cheap small cells" and "satellite technology" but it's what it takes to address wireless use cases that currently aren't addressed.

5G SA isn't still available for the broad masses yet.. and they are talking of 7G? I had the chance to test it in Germany with Telefonica as it can be activated for free. It saves a lot of battery compared to 5G NSA. But they still had smaller problems with hand-overs to LTE and GSM. Colleagues told me that the 5G NSA battery consumption problem is pretty much a solved problem with other basebands and only Pixels are…

These industries are pipelined. When generation N is in operation, N+1 hardware and software must be in development, N+2 specifications must be in endless committee discussions phase, and N+3 techs must be worked on in labs, etc.

This is an underrated point. PCIe, DRAM, and WiFi standards are similar. I watched a YouTube video about how PCIe 6.0 was developed, and, damn, the pipeline is long and very complex. Even test equipment has a separate/parallel pipeline.

In Germany I notice a massive difference in 4G and 5G. If I see 4G on my phone and know I can put it away again if it's not some kind of an emergency because it's basically unusable. I am not sure what is going on here, probably the telcos that are limiting the bandwidth.

2G is being shutdown (or already has) in many countries and those old phones and core services will need to be replaced.
