Unlikely. 5G hit the wall on UWB (Ultra Wide Band; 10-100GHz) because geniuses who were doing marketing for its transfer speeds did not realized that such high frequencies are disrupted with minimal amount conductive material in the air - so surprise surprise, 5G UWB does not work when you are behind a wall, it does not work when your big head full of water is in the way of BTS and most perplexing for common folk, it…

Well mmWave was never for large areas. It's for ultra high density like in stadiums with 100k people. You know those cases where current networks are completely unusable because they saturate.

Its extremely limited range and penetration is a benefit there because you can put up thousands of cells without them interfering with each other.

It was also meant for offices as a managed WiFi replacement. Stuff like that. In this vision every laptop would have 5G built in and could work anywhere. It just didn't take off because of the chicken egg problem. Not many phones with mmWave. Not many providers with it.

The speeds thing was just marketing BS as usual but mmWave did have benefits in niche scenarios.

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.

Right and society only works on one thing at a time

Yes, why working on something that "may" be beneficial in the far future? This is like inventing a 128-bit CPU architecture. Nobody would be able to utilize like even 1% of that, even with AI.

I'm not sure what performance improvements you're expecting with cell phone generations but most of it's pretty incremental. I don't think 7G is going to be even twice as fast as 5G on the same frequencies. It should be more stable, maybe millimeter wave will get deployed more, but it won't be wasted at all, lots of towers are going to be running at 100% utilization.

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…

And companies are selling electric cars even though not everyone has a petrol car… I remember people saying the same thing about 4G relative 3G and 5G relative 4G.

2G -> 3G -> 4G were all massive jumps that all enabled new use cases.

I doubt majority of phone users who have a decent 4G connection would notice the difference if they upgrade to 5G.

We really need a hybrid short-haul standard designed for short-range transmission. Something that uses low-frequency spectrum currently allocated to 5G but isn't locked to a single carrier and the protocol can be shared between WiFi and Cellular. Staking out some new frequencies would be great too.

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.

Over 5G you need specialized suits, like fighter pilots have.

I feel like 5g is worse

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.

The thing that changed with 5G is that my iPhone 13 Pro‘s battery has been draining 30% faster. Enable the hotspot and it gets burning hot.
