5G is just instructions on how devices should talk over radio waves. The waves the devices decide to talk over very dramatically. On the short-range end, they can talk on 30-60ghz bands; these bands have lots of room to talk, but they’re hard to hear, especially through walls or long distances. On the other end, they can talk on frequencies as low as <600mhz. These are great at penetrating barriers (they’re probably what you use in the middle of nowhere) but there’s less room (free spectrum real estate available) to talk.
