Unleashed is no upfront cost or subscription fees. A separate controller is not used for unleashed, one of the AP will take over as master and the others will be slave. if the Master goes down one of the slaves will be promoted to Master. Unleashed will manage all your ruckus AP, caveat as long as all on the same software version, and wlan's via one interface. Changes made there populate to all AP. Mesh in Ruckus terminology, is only for when you use wifi for the connecting backhaul. If using ethernet backhaul, then "mesh" not desirable. All AP will still interface with each other, adjust signal strength, and channels without mesh (wifi backhaul) as expected.I'm in the process of looking for unifi alternative myself and Ruckus is on my radar. Can anyone running Ruckus at home enlighten me on how management of multiple AP's works? Is there a subscritpion cost associated with the management software? I'm not willing to part with a single controller interface for configuring and managing all my AP's so I'm quite curious if this could be a drop in replacement for what I'm running now.
