    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: Embodiments include processes, systems, and devices that allow a white space base station to request available frequency ranges for white space transmission in a local area. A white space finder service models a primary user device's transmission signal propagation area using terrain data associated with the local area of the primary user device. The white space finder service also determines, based on the location of the white space base station and the modeled propagation area, one or more locally available, non-interfering frequency ranges and provides them to the white space base station. The white space base station compares the provided frequency ranges to policies and selects one or more of the available frequencies that accommodate the policies. The white space base station also maps the transmission frequency ranges to virtual frequency ranges for transmission by a software-defined radio employing spectrum virtualization.

    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.

    摘要: Dynamic time-spectrum block allocation for cognitive radio networks is described. In one implementation, without need for a central controller, peer wireless nodes collaboratively sense local utilization of a communication spectrum and collaboratively share white spaces for communication links between the nodes. Sharing local views of the spectrum utilization with each other allows the nodes to dynamically allocate non-overlapping time-frequency blocks to the communication links between the nodes for efficiently utilizing the white spaces. The blocks are sized to optimally pack the available white spaces. The nodes regularly readjust the bandwidth and other parameters of all reserved blocks in response to demand, so that packing of the blocks in available white spaces maintains a fair distribution of the overall bandwidth of the white spaces among active communication links, minimizes finishing time of all communications, reduces contention overhead among the nodes contending for the white spaces, and maintains non-overlapping blocks.

    摘要: Functionality is described for discovering a channel within an environment in which non-privileged entities have subordinate access rights to spectrum compared to privileged entities. The functionality operates by investigating spectrum units within the spectrum for the presence of the channel. In one case, the functionality operates by investigating the spectrum units in linear succession; in another case, the functionality advances in a staggered fashion over the available spectrum. Functionality is also described for handling disconnection by a node from a channel. The functionality allows the node to convey its disconnection status to other communication participants. In one case, various aspects of the functionality are implemented by performing analysis in the time domain.

    摘要: Described herein are technologies that facilitate transfer of data-intensive content between portable telephones. Phones are configured to transmit data indicative of phone location to a proxy server by way of respective cellular network data connections. When a user of a phone wishes to acquire content that is labeled as shareable on another phone, the user of the phone initiates a location-based request, which causes the proxy server to provide a list of phones that are estimated to be in Wi-Fi range of such phone. The user thereafter selects a particular phone, and the proxy server instructs that phone to activate its Wi-Fi radio. The phone of the user additionally activates its Wi-Fi radio, and a peer-to-peer connection between phones is established. Thereafter, rich content is transferrable between the phones.

    摘要: Described is a technology by which a remote or local geo-location service provides white space information that one or more client devices and/or base stations may use to determine which white spaces are available for use, e.g., for wireless networking. Because of the information, low-threshold sensing is not needed by the client devices and/or base stations to know which white spaces are available. The service computes the available white spaces for a given location based upon television transmitter parameters, elevation data, and information received regarding any operational wireless microphones.
