Early Days
I highly recommend reading the official white paper outlining the actually changes that make 5G distinct from 4G. It's boring, but most of the changes are around massively increased client density. I think it's a shame that the 5G advertising material is so heavily focused on speed, when it'll be the quality of connection that will really see a substantial benefit.
Things like OFDM and the move to sub-6GHz and super-24GHz frequencies are expected to drop network latency from approximately 20ms on LTE down to sub-1ms on 5G. The 5% low for expected network speed also increases from around 10Mbps on LTE to a flat 1Gbps.
But the vast majority of improvements require a substantial increase in the number of cells and antenna in a given region. This is going to be a very expensive upgrade, and it's going to take a long time.
