How is Wireless LAN Virtualization different from VLANs and VPNs?
Wireless LAN Virtualization works at the Physical Layer, virtualizing access points themselves. VLANs and VPNs are both higher level technologies used to segregate traffic within a network link, VLANs by tagging it at Layer 2 and VPNs by encrypting it at Layer 3 or above. Wireless LAN Virtualization does not require either, but will work seamlessly with them in the same way that it supports other technologies designed for wired Ethernet.
