Abstract
Visible light communication (VLC) has been extensively studied for car-to-car (C2C) communication due to its inherent benefits. It is the idea of using light-emitting diodes for both illumination and data communications. The main motivations are longer lifetime of high-brightness light emitting diodes (LED) and growing popularity of the solid state of lighting sources compared to other sources of artificial light. These two features have made a whole range of developing applications such as C2C communication since the level of reliability and power efficiency offered by LED are excellent compared to the traditional incandescent light sources used for lightning. Car industry and automobile lighting market are more and more motivated also to use Laser diodes instead of LED because of higher intensity (Power). Fiber Laser and Glass Photonics could be the next generation components for carto-car VLC. This paper presents the main features of physical layer for VLC based on the IEEE 802.15.7 standard including useful Modulations, Forward Error Correction Coding for single light source also a comparison to wireless RF-Technology and different weather influences are considered. These aspects would also be of main interest for safety, availability and security for autonomous driving in the future applications
