Abstract: Disclosed herein is a system for providing information related to a shared frequency spectrum to a wireless network that lacks Internet connectivity. The system may include one or more processors and memory including instructions that are executable by the one or more processors to perform operations. The operations may include receiving registration of the wireless network when a vehicle is within a communication range of the wireless network, querying a database on behalf of the wireless network when an Internet connection is available, receiving query results including the information related to the shared frequency spectrum, and communicating the information related to the shared frequency spectrum to the wireless network when the vehicle or a proxy of the vehicle is again within the communication range of the wireless network.

Abstract: Various technologies described herein pertain to providing spectrum utilization feedback from a whitespace device. A database query for a set of available channels in a spectrum (e.g., broadcast spectrum, etc.) during a time period can be transmitted from the whitespace device to a regulatory authorized database system. The database query includes data that specifies a set of channels used by the whitespace device during a previous time period prior to the time period. Responsive to the database query, a response can be received at the whitespace device from the regulatory authorized database. The response indicates the set of available channels in the spectrum during the time period, where the available channels are unassigned to licensees at a location of the whitespace device during the time period. Moreover, the whitespace device is configured to opportunistically communicate in the spectrum over one or more of the available channels.

Abstract: The subject disclosure is generally directed towards a technology by which non-contiguous channels of unequal bandwidth may be aggregated for use by communication devices. A data stream is partitioned (e.g., via puncturing) into partitioned data streams for communication over aggregated non-contiguous channels, one partitioned data stream per channel, in which partitioning is based upon each channel's bandwidth. Secondary puncturing may be used on any partitioned data stream that is to be transmitted over a channel associated with a regulatory constraint, e.g., a regulatory mask. Database querying, which may include providing device filter characteristics, may be used to obtain the set of channels available for use, along with any regulatory mask associated with a channel.

Abstract: A technique for a wireless device to obtain white space information from a component configured for cellular communication, such as a cellular phone. The wireless device and cellular phone may communicate using a short-range connection, such as a peer-to-peer connection, ensuring that the white space information, which is location based, generated by the cellular phone is also accurate for the location of the wireless device. With such white space information, the wireless device can comply with regulatory requirements for white space use by accessing a regulatory database identifying, by location, available white space channels. When the cellular phone is configured for accessing a wide area network, the cellular telephone may provide the white space information as a set of channels available for white space communication. Channels of the set may be prioritized based on one or more parameters, including frequency, permitted transmit power or detected noise.

Abstract: Described is a technology by which available radio frequency channels are switched/varied by communicating devices according to a frequency hopping pattern. The pattern may be a pseudorandom pattern, which may be weighted based at least in part on channel interference data. As also described herein, interference-related data may be used in a decoding scheme.
