What he means is that 5G offers only a ~15-20% increase in thoroughput with it's new set of modulation schemes given the same frequency span using 4G. So the increase in performance has to come from new frequency use. They'll steal half of C-band from satellite uplink but then all that's left is millimeter wave to truly get more thoroughput.
And that does have the problem about the propagation characteristics.

- maffydub 7y ago5G isn't just about bandwidth, though. There's quite a useful diagram at the bottom of https://techblog.comsoc.org/2017/03/02/itu-r-agrees-on-key-performance-requirements-for-imt-20205g/ https://techblog.comsoc.org/2017/03/02/itu-r-agrees-on-key-p... showing the three key use cases. As well as "Enhanced Mobile Broadband" (which does focus on increased bandwidth), there's also * "Massive IoT", which focuses on reducing power requirements and increasing the number of devices that can be served in a single cell (assuming they all transmit very little data) * "Low Latency", which focuses on better scheduling and quality of service.
