LiFi Technology Feasibility Study for Car-2-Car Communication

The car-2-car communication is one functionality already accepted by most important car manufacturers as a “must have” for the next generation of cars. Such a functionality will increase the road safety by enhancing drivers awareness about road conditions and eventual obstacles. It can be also used to inform the cars behind about risky situations in order to trigger early avoidance actions (e.g. breaking). In order to standardize this type of communication, it was created the Car2Car Communication Consortium who's task is to choose between multiple technologies and design a common architecture which allows cars communication between different OEMs. The current paper presents an analysis of the LiFI technology applied to car-2-car communication: it is proposed a new solution for the implementation which is an extension of a functionality already available in new cars: automatic high beam controller.

I. Introduction

The car-2-car communication functionality is a functionality highly researched in the last years due to multiple benefits that might bring, and several solutions have been proposed in this direction.
