Downvote all you want but this is why Verizon stopped rolling fiber out and why Google Fiber fails in most places. It doesn't make financial sense to hard wire every house with fiber when you can get higher speeds (20 Gps) over the air with the next generation of wireless technology. It will be cheaper to deploy and will have far broader reach.
It has not been proven that you can get those speeds consistently. You typically need line of sight, no trees, even no rain for the really small bandwidths.
This is for outside point-to-point, not for receiving indoors. Serves the same purpose as last-mile fiber, not wifi. The 5G lands service at the location and you use wifi inside to access it. Just like you would with fiber/cable/dsl.
