What's the point of 6G?
The only real improvement of 5G over LTE is reduced latency. Given the same spectrum, 5G is no faster than LTE, and even if you use denser QAM constellations the improvements at this point are marginal (and you'll pay for it with range, because Shannon's Law)
The only reason 5G is (or rather will be, eventually) capable of achieving the very high speeds its backers bragged out is by using very wide swathes of spectrum - which means going way up in frequency where range is short and almost anything can block it. That's fine if you want to outfit a stadium or Times Square with fast cellular, but it is useless in most places.
From the sound of the article, 6G will go even higher in spectrum into terahertz range, to find even bigger swathes of spectrum to enable even higher speeds. So what's the use case for that, given that 5G using mmwave will be able to exceed 10 gigabits? Nevermind who the hell can use that in a phone, no one could ever use that much to their home. Heck, most office towers probably couldn't use that much even if everyone is on a Zoom call at the same time.
