As far as I can tell 5G needs a repeater every few metres. That's going to be utterly useless where I'm at. You can't get a signal most of the time when 4G masts broadcast for miles. You can't get an unbroken signal on major road and rail routes with 4G.
It would be cool to have a full node on your phone but I can't see how it's going to happen.
Straight line, nothing between and the range is close to 500 meters.
Buildings, billboards, bridges and everything else in a crowded city and the distance drops below 100 meters.
In a city like mine with an area of 500km...that's a lot of antennas.
But 5G adoption will have zero effect on
BTC. You can still mine with 3G, there is absolutely no need for 1GB/sec speeds.
But the faster internet connection you have, it will better to access, and you don't have any problem with the transaction. .
A normal tx is around 250 bytes of data. 2G offers ~ 40
Kbits speeds.
