    摘要： There is provided a computer-implemented method for transmitting data over a wireless network using white spaces. A first white space transmission channel is determined for communicating with mobile client devices. Wireless communication takes place with the mobile client devices over the first white space transmission channel. If the first white space transmission channel becomes unavailable to one of the mobile client devices because of the presence of a primary user on the first white space transmission channel, a different white space transmission channel is determined for communicating with the mobile client device that is affected. The first white space transmission channel may become unavailable to the affected mobile client device, for example, because a primary user begins using the first white space transmission channel in proximity to the affected device. The primary user may be a wireless microphone. Thereafter, communication with the affected wireless device takes place on the different white space transmission channel, while unaffected devices continue to communicate on the first white space transmission channel. Also provided are an exemplary wireless base station and an exemplary mobile client device.

    摘要： A system and method for peer based localization system using radio technology, such as Bluetooth or Wi-Fi ad-hoc technology that enables mobile devices such as cell phones, smart phones, laptops, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs, etc. to discover their physical location relative to one another. In addition, the peer based localization can use a plurality of radio technologies to increase the accuracy of the physical location estimates. Additionally or alternatively, the peer based localization technique can be combined with infrastructure based location techniques, such as triangulation, GPS, or infrastructure based Wi-Fi localization in order to transpose virtual coordinates into physical coordinates.

    摘要： Functionality is described by selecting a channel in an environment in which non-privileged entities have subordinate access rights to spectrum compared to privileged entities. The functionality operates by identifying spectrum that is available to all nodes involved in communication (where the nodes are associated with non-privileged entities). The functionality then generates a suitability assessment for each candidate channel within the available spectrum. The functionality selects a channel having the most desirable suitability assessment. The functionality can form a suitability assessment for a candidate channel of arbitrary width, e.g., by combining suitability assessments associated with constituent spectrum units within the candidate channel.

    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.
