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 system can be used to provide a method of compensation. The method includes providing a Tx level signal indicative of a desired signal level along with a Tx signal. A gain modifier adjusts the gain used on the Tx signal based on the Tx level signal. The adjusting can be done with a controller that uses feedback from the actual power level of the Tx signal provided by the gain modifier to ensure a desired power level of the Tx signal being transmitted from an antenna is maintained.

Abstract: Exemplary embodiments are disclosed of current control circuits and methods of modulating supply current from a first device (e.g., a telematics control unit (TCU), etc.) to one or more second devices (e.g., one or more compensators, etc.). In an exemplary embodiment, a method includes modulating a supply current from a first device to a second device into different current values for reporting different information from the second device to the first device. An exemplary embodiment of a current control circuit includes a variable voltage source electrically coupled with a current source and a current sink. The current control circuit is configured to modulate the supply current from a first device to the second device into different current values for reporting different information from the second device to the first device.

Abstract: A compensator system includes a control loop with a gain modifier coupled to an antenna. A control unit is configured to adjustably control the gain of a Tx signal being provided to the antenna by the gain modifier. The control unit receives feedback from a first detector connected to the output of the gain modifier that allows the first control unit to ensure the gain modifier is providing the appropriate amount of gain. A signal level can be provided to the control unit to set the desired output level from gain modifier and the signal level can be determined adjacent a transceiver that is separated from the gain modifier by a length of cable.

Abstract: A method and an apparatus establish a distance as well as to a vehicle. In the method for establishing a distance between a vehicle and an infrastructure device, at least two vehicle-mounted reception devices receive a signal transmitted by the infrastructure device. Each of the vehicle-mounted reception devices contains at least two antenna elements. For each reception device, a reception device-specific distance between the vehicle and the infrastructure device is established in accordance with the antenna signals generated by the antenna elements, and the shortest of all the reception device-specific distances is established as the distance.
