What do I need to share business class internet via a wireless point to multipoint system in a rural neighborhood. Lots of trees and houses. None of the ISP's in my area offer broad band to the houses on my hill. not a large area but I think they don't want to upgrade the lines as they are underground. I would think 4 to 5 hundred yards to the farthest house and it would only be 3 to 4 houses.
