I really like this observation.

In case a non-freq-wonk comes by: This a callback to the mm wave part of 5G. It's signal covers an area so small, you can quickly exit it at a walk. Mobile PR says it's awesome while you're in it.

It's the exciting part of 5g everyone talks about despite its somewhat narrow application. I guess busy subway stations are a good fit as they have large numbers of people in a tiny area. And in larger stations you can deploy multiple cells with minimal overlap to split the load.

My hope is mm wave cells start springing up at music festivals. Those and sports venues are the main use cases.

Even with regular 5G (sub 6 ghz) you'd take advantage of improvements over LTE like massive MIMO and more precise beamforming. All leading to more people using a network at the same time. Also anecdotally I've found that at music festivals, when cellular data doesn't work, texting or calling usually works fine (At least on AT&T)

It is! Even better, I live across the street from one. I get 5G home internet at 1GBps, faster than my cabled provider can achieve.

Nice. Cap?

What router do you use?
