4G (AIUI) uses different frequencies, is a sunk cost, and 5G needs new gear, so someone has to pay for upgrades and the 5G frequency auctions.

- vel0city 2y ago4G and 5G can use the same frequencies, but they don't coexist on the same frequencies like the different revisions of WiFi can. 5G can also operate on additional higher frequencies than regular 4G deployments. But often a lot of 5G you see deployed are in the same 700-1900MHz-ish kind of range.
