摘要： An apparatus for improving the link margin of a communication link includes a variable rate vocoder which decreases the output bit stream rate it produces so as to reduce the amount of information having to be transmit in the communication link. In one embodiment, the variable rate vocoder includes a plurality of vocoder portions, each of which produces a different bit stream rate. The selector is used for selecting among the output bit streams produced by each vocoder. In another embodiment, a logic device is coupled to the output of the vocoder. The logic device, upon receipt of a control signal, truncates the less important bits. The method for improving link margin includes reducing the vocoder output rate thereby reducing the amount of data being transmit in an communication link. The method also includes using increased error correction coding and transmitting at increased per bit power levels to increase link margin. A device knows to increase the link margin whenever it receives a request to do so, which request is based upon poor signal quality.

摘要： A satellite-cellular communication system includes a satellite based transceiver for transceiving two-way communications originated at a user terminal. As a part of call set up, a controller determines whether the user terminal should transmit in the uplink in either a wide band mode of operation or in a narrow band mode of operation. The controller then specifies to the user terminal the mode of operation through the transceiver.Whether the user terminal transmits in the uplink in a wide band or in a narrow band mode depends upon factors including the type of device, channel usage and efficiency in the channels to and from the satellite transceiver and the signal quality of the signals received at the transceiver.

摘要： The concepts relate to broadcasting white space utilization. One example can interact with a wireless device that is configured to obtain authorization to use a set of radio white space frequencies in accordance with one or more constraints. The example can obtain an individual radio white space frequency and associated individual constraints. This example can also utilize the individual radio white space frequency for network access independent from the wireless device that is configured to obtain the authorization.

摘要： A wireless peer-to-peer protocol that supports fast and low power joining to an existing group. The protocol may be an extension of a peer-to-peer protocol that supports a sleep state for a device controlling the group. When a device is seeking to join a group at a time when the controlling device is in a sleep state, another device that has information about the controlling device may provide information to the joining device that may then be used by the joining device to more quickly, and using less power, synchronize with the controlling device. The information may include information about a channel used by the controlling device or about timing of availability of the controlling device. The information may also reveal whether the group provides a service being sought by the joining device or may otherwise influence whether the joining device will attempt to join a group.

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 access point in a wireless network that may be adapted to transmit location data indicating its location to other devices within range, including other wireless access points and client devices. In some embodiments of the invention, the location data may be embedded in a control message or announcement transmission transmitted by the wireless access point, or other message conventionally used to broadcast network characteristics necessary for a client device to establish a connection to the wireless access point. In terms of the Open Systems Interconnect (OSI) layered model of a network, layer 2 control messages, including beacons, probe responses, or other suitable transmissions may be used for control messages or announcement transmissions. The other wireless access points and client devices may receive the location data broadcast by the wireless access point without establishing a connection to the client device. Devices receiving the location data may use the received location data to determine their own locations, and may provide the determined locations to consumers of location data.

摘要： A mechanism for a wireless device to obtain access to network connectivity through a WAN-enabled device. The wireless device may use peer-to-peer communication to request the WAN-enabled device enter a mode in which it serves as an access point to its WAN. The wireless device may then associate with the WAN-enabled device in its role as an access point to access connectivity services. Such a capability may be used, for example, to allow a wireless computing device to gain access to the Internet through a smartphone or other device that has Internet access, and can also be configured to communicate in accordance with the Wi-Fi and Wi-Fi Direct standards.

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.
