Optical amplification on automotive VLC applications

With the increased demand of visible light communications (VLC) with applicability in vehicular applications, there is also a need in raising light intensity received on the receiver side from the active light sources, to be able to form a temporary end-to-end network through physical measures, besides electronic ones. The present article tackles the present demands of vehicular VLC links. By analyzing the road infrastructure and the light sources, preliminary calculations were conducted towards practical applications. Interdisciplinary observations have been taken into account, in order to direct feasible solutions, and to raise the signal to noise ratio (SNR) of the active link over longer distances. The high frequency of road accidents raises demand a complex safety net in order to reduce their encounters. The complex measures have to involve multiple technologies radio-frequency (RF) as Dedicated Short Range Communications (DSRC), Vehicle-to-everything (V2X), with non-interference ones as VLC. The main advantage is their complementarity, which in case of congestion their mix can achieve their common goal.
