Abstract:
A system and method for providing a seamless transition between access points for mobile devices. The method comprises associating a unique identifier for a plurality of mobile stations with a unique identifier for a first network in an acknowledgment table, then, upon receiving a frame from a mobile station, acknowledging the reception of the frame if the frame includes the unique identifier for the mobile station and the unique identifier for the network. The transfer of operation between access points is effectuated through the use of control circuitry which transfers portions of the contents of the acknowledgement table between various access points. This has the effect that the mobile stations does not sense a change in access points and thus the roaming from a first access point to a second access point is seamless.
