Car to X Communication with Optical Wireless as Support and Alternative to RF-Technologies for Roads and Future Transportation

Among the different types of lasers and light sources for Communications, new components are becoming more and more important also for Optical Wireless and Optical Sensing applications. In this contribution, combinations of Optical- and RF-Wave Propagation are illustrated, considering also new technologies of lasers and fibre lasers. The presentation includes Optical Wireless Communication (OWC, well known as Free Space Optics (FSO)) as hybrid transmission methods with telecommunication technologies (like WIFI, RF- and Satellite Communications) and also Sensing Technologies (like LiDAR and radar combinations). Important characteristics of physical layer including useful Modulations, Forward Error Correction Coding for single light source are considered. Furthermore, different cases for enhancing the SNR in daytime condition are discussed. The contribution deals with possible fields of application for optical wireless in conjunction with automated driving.
