Abstract

A wireless local area network (WLAN) (36) includes mobile devices (26) that are allowed to transfer wireless connections between WLAN subnets or channels having different access points (24). The access points connect to a central controller or roaming server (22) that supports seamless hand-offs of mobile devices from one access point to another access point. The roaming server supports the reassignments of session data parameters from one access point to another (e.g., access point address spoofing) so that the mobile device can use the same parameters for comminicating to a new access point. The roaming server also supports the seamless handoff of a mobile device from one access point to another by using a master-slave switch technique across two piconets. The roaming server also facilitates the control of access points by establishing a host controller interface and wireless protocol stack in the roaming server then encapsulates host controller commands in a packet based network protocol used for communication between the roaming server and the access points.
