In-vehicle power line communication (PLC) holds great promises as an enabler of in-vehicle communication without increasing weight, volume, or cost of the wiring harnesses. In this paper, we join a few recent works and present channel measurements for a specific compact car. We discuss and compare our measurement results with those obtained in previous campaigns. Furthermore, we evaluate our measurements from the viewpoint of high connectivity. That is, we are interested in the suitability of PLC for applications that require a reliable link from any node to any other node at any time. Perhaps not surprisingly, we find that advanced transmission techniques such as multihop or frequency diversity are necessary to achieve this goal.
