Abstract: Automotive area networks (AAN) have a substantially fixed network topology, meaning that the physical media used for communications between devices included in the AAN is known. For example, the physical connections within an AAN, sometimes provided by wiring harnesses, can include fixed lengths of twisted pairs of wire (“twisted pairs”). Pre-compensation parameters related to characteristics of the twisted pairs can be determined at the factory, and loaded into the memory of devices connected to the AAN. These pre-compensation parameters are used to improve the fast wake up and link acquisition times of connected devices. Various characteristics of the physical communication channel are measured or estimated as a function of mechanical, ingress, climactic, and environmental variations (MICE), and used to update the pre-compensation parameters.

Abstract: A front-end module and antenna can be shared between two radio transceivers operating in coexistent radio frequency (RF) communication bands. For example, a first of the two radio transceivers may operate in one of a Long Term Evolution (LTE) band or an Industrial Scientific Medical (ISM) band, while a second of the two radio transceivers may operate in an alternative one of the LTE band and the ISM band. Use of a diplexer in the shared front-end module to pass RF signals between the two radio transceivers and the shared antenna can allow for sufficient isolation to avoid interference between transmit and receive operations in the coexistent RF communication bands.

Abstract: Processing video data for delivery to a remote wireless includes receiving video data from a video source and receiving position and motion information regarding the remote wireless device. Operation also includes, based upon the position and motion information regarding the remote wireless device, determining an anticipated Quality of Service (QoS) available for servicing of transmissions to the remote wireless device and determining video processing parameters based upon the video data and the anticipated QoS. Operation further includes processing the video data based upon the video processing parameters to produce an output video stream and transmitting the output video stream for delivery to the remote wireless device. Operation may also/alternatively include altering wireless transmission parameters of a transport stream servicing delivery of the video data to alter the anticipated QoS.

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.
