And to add to that idea, put another site in the area maybe to the South to shed some of the load from the current AP. This of course takes careful planning with coverage overlaps and frequency re-use to avoid self interference or using up the spectrum needlessly. Deploying systems that have some sort of time synchronization also helps a great deal. Self interference can be more easily controlled. In a metro market with a lot of noise, you would be surprised how well it works, even when competing with another WISP. When I worked for EarthLink, we were able to do this in Philly with a competing WISP (In this case using Canopy). It was hard getting both sides to the table to adjust network timing issues, but after that was done most of the interference problems went away.
It is very hard to make any type of carrier sense collision avoidance (CSMA) technology not interfere with itself and get maximum frequency reuse.
