900 MHZ as Backhaul

We are seriously considering switching a backhaul we have from Waverider to 900MHZ canopy. With the Waverider stuff we had to load in a special file to get the ping times down for a backhaul. Our scenario will be one ap talking to one SM. Basically point to point.
What settings will we have to tweak, if any, for the canopy gear? One the waverider stuff we went from 40MS pings to 7 MS pings with their special file specifically for point to point.
Anyone doing this?
