In-Vehicle Visible Light Communications Data Transmission System Using Optical Fiber Distributed Light: Implementation and Experimental Evaluation

Abstract

Visible light communications emerges as a promising wireless communication technology that has been found suitable for numerous indoor and outdoor applications. In this article, a new in-vehicle VLC system is designed, implemented, and experimentally evaluated. The purpose of this new system is to provide car passengers with optical wireless communications. The proposed system consists of a VLC emitter integrated into the vehicle’s ambient lighting system and a mobile VLC receiver. Unlike any previous works, this article proposes a VLC emitter in which the light from a 3 W LED is distributed on a 2 square meter surface using 500 optical fibers whose main purpose is a decorative one. The proposed prototype has been implemented on a car and evaluated in relevant working conditions. The experimental evaluation of the proposed system has demonstrated the viability of the proposed concept and showed a data rate of 250 kb/s while providing a BER lower than 10−7. As far as we know, the proposed concept is totally new in the VLC literature, opening a new area of utilization for VLC technology: using VLC with optical fiber distributed light.

Enhancing LED modeling accuracy to extract practical parameters and compare simulation

“…Future work includes the explore of LED modeling advancement such as physics-based models that collect the effects of nonlinear behavior and memory in LEDs, and the attainment of the effects of design parameters on LED nonlinearity and dynamic response can improve the understand of LED behavior and the evolution of enhanced LED chips and its modulation [13].…”

Self-synchronizing on-off-keying visible light communication system for intra- and inter-vehicle data transmission

“…Far less is said about the use of VLC for intravehicle communication. [24] et al is one such piece that looks at utilizing VLC for in-vehicle communication. Here, data is distributed to various areas of the vehicle using fibre optics before the free space channel.…”

Three-Dimensional Division of Visible Light Communication Irradiation Area

“…Visible light communication (VLC) [ 1 ], as a new optical wireless communication method, has been explored for a wide range of applications, for example, indoor illumination and communication [ 2 , 3 , 4 , 5 ], indoor positioning [ 6 , 7 , 8 , 9 , 10 ], vehicle-to-vehicle communication [ 11 , 12 ] and vehicle–road coordination [ 13 , 14 ]. It is the most potential supplement to 5G wireless communication [ 15 , 16 , 17 ].…”
