A system for controlling access to priority access wireless resources divides a radio spectrum into first wireless resources for use by general access devices and second wireless resources for use by priority access devices. A base station receives, from a server, information concerning the first and second wireless resources, including resource entries corresponding to each of the first and second wireless resources. Upon receiving a request for available wireless resources from a general access device, the base station provides one of the resource entries corresponding to the second wireless resources. The system includes a general access device which aggregates resource entries for the first and second resources for communication with another general access device. When the general access device detects priority access to the second resource, the general access device either releases the second resource or reduces transmission power on the aggregated first and second resources.

Priority access to a priority access channel

Techniques for spread spectrum wireless over non-contiguous channels are described. In at least some embodiments, a set of channels is selected for wireless communication, with at least some of the channels being non-contiguous (e.g., non-adjacent) from one another. A spreading sequence is selected, such as based on attributes of a selected set of channels. Communication data that is to be transmitted over the set of channels is combined with the spreading sequence to generate a spread spectrum signal. The spread spectrum signal is then divided into multiple sub-signals for transmission over the set of channels.

Spread spectrum wireless over non-contiguous channels

Techniques for priority access to a priority access channel are described. In at least some embodiments, a portion of the radio spectrum is divided into general access (GA) channels and priority access (PA) channels. Levels of access to the different channels are controlled based upon priority levels of devices attempting to access the channels. For instance, embodiments employ a channel database that tracks available GA channels and PA channels, and notifies various devices of the available channels. The channel database may also track keys for PA channels that enable authentication of devices for priority access to PA channels. In at least some embodiments, tracking available GA channels and PA channels enables underutilized radio channels to be identified for various uses, such as for wireless broadband communication.

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.

Obtaining information related to a shared frequency spectrum on behalf of a wireless network that lacks internet connectivity

Techniques for tethering parameters for a tethering connection are described. Implementations, for example, enable a tethered connection between a tethered device and a host device to be provisioned in various ways.

Tethering parameters for a tethering connection

Techniques for wireless connectivity using white spaces (e.g., television (TV) white spaces) are described. In at least some embodiments, movement of a device operating as a white space access point is monitored by local sensors within the device. Movement data that is gathered by the local sensors is used to determine an upper bound of distance traveled. When the upper bound reaches a threshold distance, various actions can be performed relating to the data transmission, such as to cease transmission or to utilize different portions of the radio spectrum.

Wireless connectivity using white spaces

Techniques for guard band usage for wireless data transmission are described. In at least some embodiments, white spaces in the radio spectrum (e.g., television (TV) white spaces) and guard bands between licensed bands of the radio spectrum are leveraged for data transmission. Based on available white spaces and service deployment in the licensed bands, various decisions can be made regarding how to leverage white spaces and guard bands for wireless data transmission.

Guard band usage for wireless data transmission

Techniques for guard band utilization for wireless data communication are described. In at least some embodiments, guard bands can be leveraged to transmit wireless broadband data and/or other forms of wireless data. According to one or more embodiments, signal activity in a wireless channel that is adjacent to a guard band is monitored, e.g., while the guard band is being utilized for wireless data communication. In at least some implementations, if the signal activity exceeds a signal activity threshold, usage of the guard band channel can be adjusted to mitigate interference with signal activity in an adjacent channel.
