Over-the-Air: Virtualized

The virtualized architecture builds upon the layering architecture, but introduces the notion of complete wireless network virtualization. Wireless LAN (WLAN) virtualization involves creating a unique virtual wireless network (a BSSID) for every mobile device. This allows the network to be partitioned for each client, providing each client with its own set of 802.11 autonegotiated features and parameters.
It's important to note that the per-device containment provided by virtualization differs from the per-device rules and access control enforcement provided by the other architectures. Containment addresses the over-the-air behavior of the client directly, using the standard to enforce the segmentation and the tight resource bounds. The client's cooperation is not needed or expected. Access control, on the other hand, is fundamentally a cooperative scheme, and clients can choose not to participate in the optional protocols required to make bidirectional access control work. Even downstream policy enforcement cannot stop a client from transmitting what it wants to upstream.
However, virtualized Wi-Fi partitions are able to maintain the per-device containment, by transferring control of the network resources from the client to the network, and then using Wi-Fi mechanisms from the network side to ensure that client behavior is limited to the resources that the client is allocated.
