5G doesn't solve a bandwidth problem, it solves a latency problem. 4G has a latency of ~50ms, 5G is more like 1ms. 50ms is noticeable in areas like remote robot control, video conferencing, remote surgery, IoT, remote control vehicles (not on the roads).
That's not true or am I misunderstanding something?
"Latency was more consistent than the other measures across the 4G networks tested (an average of 53.1 milliseconds)."
I do work for a UK mobile company and was in a presentation about exactly this. 5G means more realtime.
Yes, 4G _can_ do lower latency, but in general it doesn't, especially in built up areas, where 5G beamforming outperforms .
