I don't think it'll happen in areas with wide geographic coverage, like the US, anytime soon.

Sure, 5G carriers salespeople will promise you the world, but if you actually bite, you'll see that a lot of it is just promises, at this time.

In the current scheme with relatively limited towers and tower backhaul, it's just not doable.

I think they'll need, at a minimum:

- Far more spectrum

- More microcells

- More backhaul
