Not really a network engineer so cant really help with that. The 20ms is just my experience and the 1 to 2ms is the theorical number given by the people designing 5G. Found this writeup but still not really sure beyond improvements to the slot-based framework and higher frequency as being the reasons https://www.edn.com/electronics-blogs/5g-waves/4460346/5G--The-road-to-low-latency https://www.edn.com/electronics-blogs/5g-waves/4460346/5G--T... All these latency numbers vary a lot based on connection quality. As I understand you basically need line of sight for 5G to work at its maximum frequency and will fallback to what is basically 4G when such a connection is not possible. But then again the antennas/stations for 5G should be much smaller and thus easier to deploy closer to the end users.
