摘要： 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.

摘要： An indicator for a device may provide an indication that a threshold associated with a budget for a network resource has or will be reached. When a user requests a network operation that will consume the network resource, an amount of the network resource to be consumed by the operation is predicted, if possible. If the prior use of the network resource and the amount to be used to complete the network operation exceeds a threshold the user may be warned and given an opportunity to cancel the operation or adjust the way in which the operation will be performed. If the amount of network resource a network operation will consume is unknown, a rate of use of the network resource is determined and a time until the budget is reached is estimated.

摘要： A communication system that provides fast and reliable communications. The system is suitable for use in connection with wireless computing devices in which transmission errors may occur because of channel conditions, such as interference. Channel conditions causing transmission errors may be bursty and transient such that the errors temporarily overwhelm an error control code. By combining data received for multiple transmission attempts of a packet that fail error checking or that pass error checking with low reliability, a reliable representation of the packet may be quickly constructed. Though, combining may be omitted when a transmission attempt is received that passes error checking with high reliability.

摘要： A wireless device that automatically forms a connection to a remote device in accordance with a peer-to-peer protocol. The remote device may be designated as an auto-connect device for the wireless device such that, when the wireless device determines that it is in the vicinity of the auto-connect device, it can re-form a connection to the remote device based on stored information for re-establishing connections among a persistent group of devices, but without any express user input. When a user requests that the wireless device perform a function that involves interaction with an auto-connect device, that function may be performed with the delay associated with forming a connection. Any of multiple techniques may be employed for identifying devices designated as auto-connect devices and for determining when the wireless device and a remote, auto-connect devices are in close proximity.

摘要： A computing device configured for wireless communication may effectively control adaptation to channel conditions. The device may be configured to identify and classify conditions impacting performance of a channel so that appropriate adaptations may be made. Interference may be detected by correlating received signal strength and packet errors. High received signal strength correlated to a high packet error rate may signify presence of a source of interference. Once a source of interference is detected, other criteria may be used to determine the nature of the interference so that an adaptation that is minimally disruptive of applications can be selected. Additionally, channel degradation may be predicted by monitoring trends in error rates, including Forward Error Correction rates, and adaptation may be used before packet error rates exceed an unacceptable level.

摘要： A wireless computer that pairs with a remote audio-video presentation device, such as a television. As a result of the pairing, a communication channel is established for the computer to transmit audio-video content for presentation through that device. Additionally, as part of the pairing, the computer and remote device select a side channel for communication of user commands. The wireless computer may display a user interface through which a user may input commands that control the manner in which the remote audio-video device presents the content. As a result, a user may use the wireless computer as a remote control for the audio-video device, controlling both the content presented and the manner in which it is presented. The side channel may use different frequencies than the channel used to communicate audio-video content, and may use very low power at frequencies in the digital TV spectrum.

摘要： A wireless communication system that concurrently communicates information in multiple regulatory domains to facilitate audio/video media streaming and other high bandwidth operations. One domain may be licensed and the other may be unlicensed. Transmission in the licensed domain may occur in white space in the domain, and the amount of information transmitted in that domain may be limited by regulations. The amount of information conveyed in the licensed domain may also depend on channel conditions in either or both of the domains. As a result, the relative amount of to information transmitted in each domain may vary dynamically. The system includes a transmitter that dynamically determines weighting coefficients applied to each of a plurality of channels to set power levels in both domains to achieve a desired metric for the overall communication. A corresponding receiver assembles the substreams into a stream that can then be displayed or otherwise processed.

摘要： A process for controlling radio transmission and/or reception to enforce certain constraints with either single or multiple radio communication is disclosed. In one embodiment, the enforcement control may be by the corporate administrator (such as an Information Technology (IT) department) that is responsible for the company's wireless devices. In other embodiments, the enforcement control may be by a regulatory group having governmental control over wireless communication. In yet another embodiment, the enforcement control might be by a provider group, such as a provider of a local private or semi-private wireless network desiring certain controls over the users of the network.

摘要： A bootstrapping technique for wirelessly obtaining white space data that may be used to identify an available white space channel for connecting to a service. Portable wireless devices may collaborate to provide white space data to a device requesting such data. A requesting device transmits a request for the white space data using, for example, an unlicensed band. A device receiving the request may transmit a copy of the data to the requesting device. The transmitted copy may be obtained by the receiving device from a local data store or may be provided from a database server to which the receiving device is connected. In the later case the receiving device acts as a proxy between the database server and the requesting device. Once the white space data is received by the requesting device it may be used to select a channel for communication in the white space.

摘要： A computing device having a software defined radio (SDR) wireless network interface is automatically configured to support a wireless service in response to a request from the user to access the service. The computing device may determine the appropriate profile and obtain it by querying a remote database. The query may indicate the computing device's current location, though location information may alternatively be determined by a server coupled to the database. The communication profile is downloaded from the remote database using an existing or available network connection. The software defined radio is configured with the communication profile and is used to access an available wireless service. Content obtained from the wireless service is presented through a user interface of the computing device.
