This paper discusses future connectivity architecture for autonomous vehicles based on the remote radio head (RRH) concept using a software-defined radio (SDR). An example is provided to show how two wireless access technologies can be implemented using this architecture.

On one side, it can fulfill the performance requirements of future use cases, and on the other side, it enhances reliability by facilitating the use of multiple wireless access for a given service. The overall approach is to exploit the power of softwarization, which aligns with the future of in-car computing technologies.
