mmWave has a few categories. There are "it works out of line of sight as long as you are in range" devices but that range is like a city block, maybe two. The idea being that you could use it in the city and there'd be transceivers on the roofs and walls of the buildings so that the city stays densely covered. So realistically anywhere you can actually get mmWave, you are probably within less than a thousand feet of a fiber optic installation.
