New 5GAA White Paper on Vehicular Distributed Antenna System

The current development of communication technologies opens up new opportunities and enables novel V2X (Vehicle-to-Everything) services in the automotive area. However, specific design constraints faced by the automotive industry lead to complex implementations, as the allowed positions and mounting spaces for antennas, communication modules, and the required cabling can be very limited. These challenges commonly require vehicular-Distributed Antenna System (DAS) approaches.

This white paper provides an analysis of the motivation for and needs associated with vehicular-DAS, as well as proposals for some vehicular-DAS design solutions. In addition, it describes the implementation feasibility and potential benefits of vehicular-DAS based on measured computer simulation results, and evaluates potential vehicular-DAS impacts on current specifications.
