Abstract

A controller directing access points to default to a virtual cell service mode which allows seamless mobility for stations in motion around a wireless network is disclosed. Responsive to identifying a first station, the controller logic may dictate tighter controls for the first station by selecting a virtual port service mode. Some embodiments can also select a native cell service mode for devices due to a connection history of the station or a MAC OUI that is incompatible with virtual cell service mode. An initial service mode can be changed due to a condition. Also, the controller provides multiple BSSIDs to each access point.
