I wonder about using last-mile wireless as a way to distribute fiber internet. Something like a fiber-connected wireless hub that provides service to customers within a quarter-mile. At a density of 10000 households per square mile (pretty high) your service area is about 0.15 square miles and you need 1.5 Tbps bandwidth or so in the air around a hub for 1 Gbps service to the household. Feasible? It's a stretch, but I assumed a very high density of customers and I think many people would be happy with 100 Mbps.
