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.
