Mobile Non line of site for police cars data access?

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?

Police love the PDA phone I have. The Samsung i700. 144K on Verizon is
only $40 extra a month for unlimited data.
