We are looking for a NLOS solution for 10 small towns (the smallest being 3500 people) spread out of a very wide area (every site would require their own AP). They want speeds above 56 Kb, and no monthly reocurring (sorry Cingular, sprint).
We are have looked at different frequency ranges and found that 900 Mhz penetrates well, but still the range isn't the best. Any ideas?
