Abstract
Described is incorporating white space networking components into a network stack. A user mode spectrum access control component determines which white space channels are currently allowed for use based upon policy, current operating status and availability information obtained from one or more sources. A white space service (e.g., in the WLAN service) receives the availability information. The white space service includes a discovery module that discovers other nodes, and a channel migration module that changes from the current channel to another channel if the current channel is no longer allowed for use. A kernel mode (NDIS layer) white space driver through a miniport driver controls the channel in use as the current channel. An automatic configuration module is provided that switches to Wi-Fi network communication when a Wi-Fi network is present, and switches back when a Wi-Fi network is not present.
