mmWave is a tool to cope with network capacity concerns far into the future. It's in its infancy right now but the ability to provide multiple gigabits over the air in certain high-traffic locations can help greatly. We're running out of midband spectrum that can provide good indoor/outdoor coverage and so it's best to look to much higher frequencies that don't have any major incumbent users to satisfy those capacity needs.
