Abstract: Exemplary embodiments are disclosed of vehicular systems including distributed active antennas, adaptive cellphone evolution (e.g., via a smartphone, mobile device, user equipment, etc.) and/or integrated access and backhaul. In exemplary embodiments, a distributed antenna system includes a central unit onboard a vehicle. The central unit includes a transceiver configured to operate in a cellular network. The central unit also includes an analog to digital converter/digital to analog converter coupled to the transceiver. Four active antennas are onboard the vehicle. Each active antenna includes an analog to digital converter/digital to analog converter and is configured to communicate with the central unit digitally. A link connects each of the active antennas to the central unit. The link is configured to transmit signals digitally and support at least 10 Gbps of bandwidth between the central unit and the active antennas.

Abstract: A vehicle USB hub system that includes a USB hub, a controller and memory unit is provided. The vehicle USB hub system collects data link quality metrics for messaging to and within a vehicle. The USB hub has a CRC error detector for detecting CRC errors in messaging received via its ports. Information regarding detected CRC errors is stored in the memory unit. The controller generates a CRC error log using the information stored in the memory unit upon receiving an indication that an error log should be sent. The controller then sends the CRC error log to a device via the USB hub port indicated.
