Abstract: PURPOSE: A wireless LAN virtualization system which automatically establishes a network allocation vector according to a beacon frame is provided to increase the throughput of MAC(Medium Access Control) by automatically setting up the network allocation vector in a virtual BSS(Basic Service Set) unit. CONSTITUTION: An AP offers a virtual basic service set. A plurality of stations is related to the virtual basic service set. Each virtual basic service set automatically establishes a NAV(Network Allocation Vectors) according to the beacon frame. The access point transmits the beacon frame. A superframe is formed in an alternative type of a CFP(Contention Free Period) and a CP(Contention Period). The period of the contention free cycle, and the network allocation vector is instituted.
