Wouldn’t latency and capacity still be an issue with 5G?
Mobile internet is also really inconsistent. It’s passable because normally you are not doing serious work on your mobile.
You can easily get 40+mb on 4G but I’d never want to for example play a FPS game online using it.
From the article I linked to:
5G also promises reduced latency. According to the specification, there’s a maximum latency of 4 ms (milliseconds) on 5G instead of 20 ms on 4G LTE today. That will deliver a better experience, too.
