"Fast forward another decade or two and 6G emerges plus other new tech, so it's all a bit of a cycle"
Savage I keep reading opinions about 6G replacing 5G and it being a completely new cycle, but I see it differently, in my opinion 6G will be more an evolution of 5G rather than being a completely new cycle. In many cases 6G will be application specific and reuse 5G frequencies. The much hyped 100Ghz plus high bandwidth 6G applications will be more akin to WiFi than mobile services, and will likely be used in short range line of site locations with large numbers of users simultaneously accessing content, stadiums, shopping centers, Railway stations, etc spring to mind.
LEO's also have frequency/bandwidth issues, since they're subject to the same limitations as terrestrial communications, the higher the frequency the shorter the range. They can use more advanced modulation techniques to squeeze more bandwidth out of lower frequencies, but that has its limitations due to noise; Also a satellite at an altitude of over 500Km, and travelling at high speed relative to the customer's on the ground, has to efficiently use it's phased array antenna's to provide services. Physics and distance means LEO's will never be able to compete against ground based communications, there are limits to the number of uses and users even with 12,000 satellites orbiting.
My point is that once the current FTTP and 5G rollouts are completed, I don't really see any major future generational upgrades from here, just a slow grind as better more efficient equipment's becomes available; Unless they somehow discover some new science fiction solution like Quantum communications.
