Because Telesphoreo is still banned from the forums but still wanted to post his experiences with 5G, I'm forwarding what he was gonna say here.
Quote@"Telesphoreo"#36 recently I was in San Antonio and got to try out the real 5G (ultra wideband). I've gotten the normal 5G as my signal and it was faster than 4G, but not by a significant amount. getting a 5G UW signal was actually a little hard to get. i had to move around the block to get a signal but once I had it, it was able to stay connected. here's a video of me running the speedtest, my home internet is 100/10 so this is faster
