This is why I'm asking, because noone is shutting down 4G anywhere. And 5G actually has LESS range than 4G.

4G is ending up as the replacement to 2G as the base network. I suspect 5G networks will be shut down before 4G ones given IoT devices are largely setting on the low power variants of LTE.

5G has more range than 4G on the same frequency bands. 5G UWB has less range than 4G.
