Since the site isn't that clear, the protocol is narrow-channel 802.11n on the amateur 5.9 GHz band. I wonder if the net throughput or range are any better than using the unlicensed 5.8 GHz band.
HamWAN founder here. The protocol is this: https://wiki.mikrotik.com/wiki/Manual:Nv2 And the sectorized spectrum plan is this: http://hamwan.org/Standards/Radio%20Frequency%20Engineering/... When choosing a protocol for cheap long-range point-to-multipoint microwave, I wanted something that was TDMA'd and not CSMA'd like 802.11. That left me with WiMAX/airMAX/NV2 to choose from. WiMAX gear was overpriced, Ubiquiti's…
Do those microtik modems support rpki? That would be my biggest gripe. Nobody will want to peer without rpki in a few years.
