Speed degrades with distance. Word is, real world is 2-6 miles per site in urban areas and 6 to maybe 10 miles in rural areas with LOS.
When cheap WiMAX repeaters come around, they'll be able to setup many in an area w/out needing to backhaul each one. Could even be put on streetlight poles that have LOS to a master WiMAX backhaul site.
