I don't personally get why mmWave part of 5G is talked so much about. 1st Google result gives less than 1% of time connected is to a mmWave network.

5G over the same cmWave frequencies 4G uses still has a benefit - but mainly for the operator! It allows them more users and throughput for the same amount of spectrum. So in a rational market, the operators should be giving you discounts for using 5G instead of charging more for it!

I just benchmarked from my suburban second floor bedroom in the US, and got mmWave (it says 5G UC which is apparently mmWave) and got 500mbit/sec

So I guess some people have it, and use it? It’s basically always on around my neighborhood, but I guess I live in a nice city and Sprint’s old HQ is down the street so that probably has a lot to do with it.

That is is T-Mobile “Ultra Capacity”, which is more like.y the midband spectrum they got from sprint.

You basically need line of sight for mmWave. Think of it like light. If you can’t see an access point, then you probably aren’t using mmWave.

Half a bit per second?

Only the US really uses mmWave.

~3.4GHz-4GHz (which is the 'primary' 5G band) in Europe can provide excellent speeds (2gbit/sec real world no problem to a phone) but without the terrible signal degrigation you get on mmWave.

mmWave will be used more in the future once the other bands get saturated, but it's a bit ahead of its time now.
