    摘要： The coexistence of a plurality of different wireless networks that concurrently operate in a common geographic region is optimized. A query is received from a wireless node requesting advice on specific portions of a radio frequency spectrum to use. A spectrum recommendation procedure is then run to generate advice on recommended portions of the radio frequency spectrum for the wireless node to use in order to minimize one or more of interference in the spectrum, or noise in the spectrum, or contention in the spectrum. A recommendation reply is then sent to the wireless node which includes information specifying the recommended portions of the radio frequency spectrum for the wireless node to use in order to minimize one or more of interference in the spectrum, or noise in the spectrum, or contention in the spectrum.

    摘要： Architecture that enables wireless narrowband devices (e.g., wireless microphones) and white space devices to efficiently coexist on the same telecommunications channels, while not interfering with the usability of the wireless narrowband device. The architecture provides interference detection, strobe generation and detection and, power ramping and suppression (interference-free coexistence with spectrum efficiency). The architecture provides the ability of the white space device to learn about the presence of the microphone. This can be accomplished i using a geolocation database, reactively via a strober device, and/or proactively via the strober device. The strober device can be positioned close to the microphone receiver and signals the presence of a microphone to white space devices on demand. The strober device takes into consideration the microphone's characteristics as well as the relative signal strength from the microphone transmitter versus the white space device, in order to enable maximum use of the available white space spectrum.

    摘要： 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.
