Visible Light Communication

Using visible light for data transmission, which is referred to as Visible Light Communication (VLC), opens a broad spectrum of applications, which shall be illuminated in this article. After a short introduction and historical overview the technical details are described. Subsequently, the most important fields of application are presented, such as location estimation in closed rooms, which is particularly well-suited for hospitals. Current standardization efforts, namely JEITA CP1221 and JEITA CP-1222 are also discussed. This article concludes with a list of recent challenges that are being worked on in the VLC community.
