Abstract: In automotive networking applications, data about vehicle's environment can be used in conjunction with a control policy to manage the performance and power usage of a networked device. The control policy can dynamically adjust the balance between link power and performance of the device's communications interface by taking into account the vehicles current situation and user preferences, e.g. location, destination, speed, sensor status, or the like. Controlling the balance between link power and performance of networked devices can be important in maximizing power savings without unacceptably decreasing network performance.

Abstract: Dynamically splitting a job in wireless system between a processor other remote devices may involve evaluating a job that a wireless mobile communication (WMC) device may be requested to perform.

The WMC device may apportion one or more tasks making up the requested job between the wireless mobile communication device and a remote device. The apportioning may be based on the availability of the at least one local hardware resource.

Abstract: A security architecture in which a security module is integrated in a client machine, wherein the client machine includes a local host that is untrusted. The security module performs encryption and decryption algorithms, authentication, and public key processing. The security module also includes separate key caches for key encryption keys and application keys. A security module can also interface a cryptographic accelerator through an application key cache. The security module can authorize a public key and an associated key server. That public key can subsequently be used to authorize additional key servers. Any of the authorized key servers can use their public keys to authorize the public keys of additional key servers. Secure authenticated communications can then transpire between the client and any of these key servers. Such a connection is created by a secure handshake process that takes place between the client and the key server.

Abstract: A remote management system employs multiple wireless links, which may include a local wireless link and a remote wireless link. The remote wireless link may be in place between a troubleshooting device held by a person located at a service site, and a remote service center for a service provider, such as an Internet service provider. The local wireless link may be in place between the person at the service site and the equipment needing service, such as a DSL model provided by the service provider. Establishing the multiple links allows the service provider to troubleshoot the equipment, without incurring the substantial cost of sending a specialized service technician to the service site. As examples, the troubleshooting device may be a smart phone, the remote wireless link may be a cellular connection, and the local wireless link may be a Bluetooth or NFC connection.

Strong authentication may thus be provided to the effect that credentials associated with specific users have been received from specific components in the system. The server may then enable the components to access selected services.

Abstract: A combined GPS and GLONASS receiver receives GPS signals and GLONASS signals. A calibration signal is generated utilizing the received GPS signals and/or the received GLONASS signals to offset group delay errors in the received GLONASS signals. The generated calibration signal is filtered through Kalman filters to estimate group delay variations in the received GLONASS signals. The estimated group error delay variations are combined with the received GLONASS signals to calibrate the received GLONASS signals by offsetting the estimated group error delay variations. When GPS signals are not available for use, the combined GPS and GLONASS receiver obtains group delay errors stored or in the received GLONASS signals to estimate calibration coefficients. The estimate calibration coefficients are updated utilizing received GPS and/or GLONASS signals.

The adapting of transmit power in a wireless communication device can be performed on a per-packet, as well as a per-link basis. Before determining to adapt transmit power, various conditions, configurations, and or operational information can be analyzed. That is, the quality of service associated with a link, the stability of the link, as well as, e.g., the stability of a current transmit rate being utilized can be considered, such that the user experience, e.g., throughput, need not be negatively affected in order to implement power savings by lowering transmit power.

The wireless controller may communicate to the media player the instructions provided to the wireless controller. Those instructions are communicated to the media player to control the operation of the application on the media player.

Abstract: Preamble and header bit allocation for power savings within multiple user, multiple access, and/or MIMO wireless communications. Within a multi-user packet, information (e.g., partial address information) related to a recipient group of wireless communication devices (e.g., as few as one wireless communication device or any subset of a number of wireless communication devices, sometimes including all of the wireless communication devices) is emplaced within a PHY (e.g., physical layer) header of such a multi-user packet to be communicated within a multi-user (MU) environment. Such recipient indicating information can be encoded with relatively higher robustness (e.g., lower coding rates, lower ordered modulation, cyclic redundancy check (CRC), etc.) that remaining portions of the multi-user packet. Various portions of the remainder of the multi-user packet may respectively correspond to different wireless communication devices (e.g.

Abstract: A wireless communication device is disclosed that is capable of utilizing multiple radio access technologies (RATs) in various coordinated ways so as to optimize, and enhance the versatility, of the device's communication capabilities. One or more RATs may be selected for use, either alone or in cooperation with each other, based on various conditions, such as channel conditions, traffic, data type, and priority. When conditions change, the originally-selected communication scheme may no longer be preferred. Consequently, the device can initiate a handover to another communication scheme. Transmitters corresponding to RATs that are not currently selected are controlled to enter a low-power state in order to conserve power. However, in some circumstances, the device may utilize both RATs simultaneously.
