I'm new to Ruckus and working on designing a Cloud WiFi solution. Zone Director has a feature called SmartRoam that disconnects clients when their signal falls below a certain level. Is that feature available in the cloud? My second, related question, has to do with how AP's deal with DHCP when controlled by the cloud. Do the AP's have a DHCP server built in, do they need to rely on an external DHCP server or are DHCP leases somehow controlled in the cloud? I'm interested in how the system will deal with clearing DHCP leases as clients come and go in a high traffic area.
