Implementation in Visible Light Communication

Visible light communication (VLC) is becoming an alternative choice for next-generation wireless technology by offering low cost, unregulated bandwidth and ubiquitous infrastructures support. This technology is envisioned to be used in a wide range of applications both indoor as well as outdoor. Visible Light Communication (VLC) uses light emitting diodes (LEDs), for the dual role of illumination and data transmission. With this leading edge technology, data including video and audio, internet traffic etc. can be transmitted at high speeds using LED light. Using LEDs is helping to drive this technology in the form of Visible Light Communication (VLC). By enabling wireless communication among vehicles and also with the traffic infrastructure, the safety and efficiency of the transportation can be substantially increased. Considering the numerous advantages of the VLC technology encouraged the study of its appropriateness for the envisioned automotive applications, as an alternative and/or a complement for the traditional radio frequency based communications. In order to conduct this research, a low-cost VLC system for automotive application was developed. The proposed system aims to ensure a highly robust communication between a LED-based VLC emitter and an on-vehicle VLC receiver.
