Abstract: 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.

Abstract: Techniques for device quarantine in a wireless network are described. According to various implementations, a device a mobile client device) that requests a connection to a wireless network is placed in a quarantine state in the wireless network. Attributes of the device are determined and connection parameters are specified based on the attributes. In at least some embodiments, the device can be released from the quarantine state subject to the connection parameters.

Abstract: A method and apparatus is disclosed by which a device in a wireless network may determine and reduce interference when using channels in restricted frequency bands and when other networks may be transmitting in the same restricted frequency. The wireless network may be a Wi-Fi system utilizing channels/frequencies in the television white space. Receivers, such as a client device and access point (AP), may determine information on one or more interfering signals and utilize the information to reduce or cancel the interference caused by the interfering signals generated by a second network. The information may be parameters or information on the structure of the interfering signal, and may be determined by retrieving stored cache information, receiving information on a beacon signal or sampling an interfering signal. The interference cancellation may be performed by joint demodulation or parallel interference cancellation.

Abstract: 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.

Abstract: 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.

Abstract: Techniques for propagating routing awareness for autonomous networks are described. In at least some embodiments, routing awareness refers to attributes of autonomous networks that route communication sessions between different endpoints. According to various embodiments, routing awareness indicates whether a particular autonomous network supports a protocol for propagating routing awareness among different autonomous networks. Routing awareness may also include performance attributes of autonomous networks. Such routing awareness enables entities involved in routing communication sessions to make informed decisions regarding routing and handling of communication sessions.

Abstract: A user's (client) computer sends a request for a listing of applications which can be downloaded from a server in an electronic marketplace and a list of functions provided by a host program. A description of an application, such as in an application manifest, provides a list of required functions and, preferably, a list of optional functions for a software application. The server sends a list of applications supported by those functions. Those supported applications are displayed to the user as being available for downloading. The user selects the desired application and the user's computer requests, and the server provides, a download of that application. The downloaded application will then operate on the user's computer using the required functions provided by the host programs, and may use any optional functions provided by the host programs.
