A Comprehensive Overview of Visible Light Communication (Vlc) Technology and Its Applications

The increase in mobile device usage and data needs, particularly for bandwidth-demanding apps like social networking, gaming, and streaming, has put a lot of strain on classic RF wireless networks, particularly indoors where the majority of data traffic happens. Investigating novel methods for wireless communication inside has become more popular as a result. In this direction, Visible Light Communication (VLC) technology is developed which can give lighting as well as communication and serving as the best replacement to the Wireless networks based on radio frequency. Ultra-high data rates, communication channels that are secure, and absence of electromagnetic (EM) wave intervention are only a few of the major benefits of a VLC system, which enable a variety of applications. Therefore, this paper presents a review of the emerging VLC technology highlighting the VLC transmitter and receiver technology with different modulation schemes utilized. Further, this review also presents different application areas for VLC technology with open research challenges. Finally, the paper concludes by highlighting the future aspects for the VLC technology.
