there will obviously be a 7g, the real question is whether carriers would adopt it.

There’s always a gradual refarming of the spectrum into the next G. Usually the most penetrating frequencies (ie lowest) are kept on the lower G to maximize legacy support. For a while I had my phone stick to 3G, which doesn’t support emergency alerts, because my jurisdiction kept sending them out for joint custody disputes at 3AM 1000km away. It was fine But the 3G became unbearable and they tightened up the alert c…

Maybe, but at least in the US, 4G wad deployable on new lower frequency spectrum that had previously been used for TV. LTE 71, 600 Mhz is…

And for those playing at home, WiFi 7 devices aren't held back by coexisting with WiFi 6 devices, for the same reason (the use of OFDMA), at least on the 6 GHz band. Legacy clients of course muddy the waters on the other bands when they're in use.

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.
I've seen an interesting corollary: 4G on an airplane at the gate is much faster than the 5G microcells inside the terminal. If I'm downloading podcasts for a flight, I do it on WiFi beforehand or on 4G on the plane. 5G in the terminal is really useful at getting you some service, but it's slow. Probably a side effect of not enough backhaul speed.

That is a very effective use case, but until we live in hive cities, stadium-level device densities are an edge case. Developing a new generation to service the 0.01% of time phones spend inside stadiums seems inefficient.
They struggle a bit on Oxford Street which as stadium like densities much of the time. I changed networks to O2 as Three became pretty much unusable in that area. Three sell a lot of unlimited data packages which their hardware seems inadequate to serve.

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 business…
This doesnt seem to match reality? e.g. Notably several major carriers in India skipped 3G entirely and went to 4G directly because it was cheaper per subscriber. Which implies less expensive equipment per unit performance?
3G to 4G was a giant leap forward and it makes perfect sense. Your parent is specifically comparing 4G against 5G.

Net neutrality would have prevented this kind of pay to win
How would it have helped? Net neutrality doesn’t mean you can’t sell your customers different bandwidth guarantees. Net neutrality is only about the connections between a provider and external networks, not about how a company handles bandwidth contention amongst its customers. Net neutrality would fix a problem like “only Facebook is accessible inside crowded stadiums” not “AT&T customers who pay more get better con…

That has not been my experience at all although that’s just another anecdote.
Seen it at several, though DFW has been the worst.
DFW is generally a terribly-run airport, though.

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.
2G also needs a tiny amount of spectrum in contrast to the newer standards, as it was designed almost exclusively for voice calls, where a few Kbps is sufficient for good quality speech. (And 64kbps, which is only 8KB/s, is considered "toll quality".)
For those who don't believe me, look up the standards yourself.

If you have a season ticket to a Premier League team you're going to be in that density once a week or once a fortnight. Whatever the percentage of time that might be, that seems frequent enough to not be an edge case.

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…
5G mm is vaporware. Virtually no one uses it (especially globally) and it is expected to be stripped out within a generation or two.
I see the mm indicator on my phone in most cities.
Why would it be ripped out?
