Buy high-speed wifi, then share it. This can be an app where people advertise their signal. Perhaps it could autogenerate a password for a the time duration and individual pays for. It could be tied into a preprogrammed router. Routers run on installed software just like a computer, so this could ask be programmed in. This would be great in student areas or tourist areas. We could even sell high power repeaters or antennas that compliment the service.
