Abstract: The present invention is a method and system for managing a secure local area network wherein the local area network includes a plurality of private networks logically linked to a wireless network having a plurality of wireless access points for isolating data traffic. The system provides authentication of the user devices, segregation of the user device into logical wireless virtual local area networks (WVLANs), and places the private networks into virtual local area networks (VLANs). By linking WVLANs with the appropriate VLANs, the management system provides segregation of user device traffic, as well as private network traffic, despite a shared physical network. By consolidating wireless networks in a multi-tenant environment, the work area of each individual tenant is expanded to a building wide roaming area, and radio frequency interference is reduced. In addition, by coupling together numerous wireless networks a greater roaming capability is created across all managed wireless networks.
