The Cisco ones have RRM (Radio Resource Manager), which will throttle the power down based on how strongly the APs hear each other. There are up to 7 different power levels. Not sure if Ruckus is that sophisticated, since they are actually really autonomous APs just checking in to the zone director. Sort of just like UniFi.

Coming from the WISP side, I asked them why they have these blasting at full power, 24/7 when the zone director surely could manage power levels when needed. I didn't get a answer. I don't think they even gave it a thought about who they might interfere with. On Friday, November 15, 2013, Robert wrote: Spectrum trashers....
