Windows Driver Kit: Network Devices and Protocols
Virtual WiFi in Kernel Mode

Virtual WiFi allows an 802.11 miniport driver to connect to, or host, multiple simultaneous connections on a single wireless interface. Beginning with Windows 7, an 802.11 miniport driver must support Virtual WiFi. You must compile or recompile the driver with the NTDDI_VERSION macro set to >= NTDDI_WIN7. In addition, the driver must support NDIS version 6.20.

The following reference topics describe how an 802.11 miniport driver implements Virtual WiFi in kernel mode.
