How about 4x4 MIMO 265QAM radios with S-OFDMA and 40 MHz TDD channels in 5 GHz bands? High bandwidth reasonable reach (say 4 miles at full rate LOS) and NLOS/OLOS capability (in fact you need OLOS/NLOS to get the decoupling of signals for MIMO spatial muxing to provide the non-coherent channels).
It will be expensive to start but as DSP and radio costs continue to drop affordable (keeping in mind the CAPEX cost to pull fibre in many areas) in 2 - 3 years.
