Not the GP, but I think the point is that he can’t get LTE at all in the desert 10+ miles outside of Ely, NV, because there are no cell towers within range. He doesn’t get 5G speeds there, but he does get LTE speeds on the 5G bands because the range is so much better. Full disclosure: I am a 5G doubter, so this is interesting to me, and I am by no means a 5G expert, so I could be totally wrong about this.

Because for a given amount of physical bandwidth & power, 5G is going to be faster. 5G utilizes the available spectrum much more efficiently to give greater speeds on a given signal.

There's no way I would have been able to stream 1080p videos on TMobile's LTE 600 MHz band at that distance from the tower.
