Visible Light Communication (VLC) for 6G Technology: The Potency and Research Challenges

This paper aims to envision the potential use of visible light communications (VLC) for a 6G technological platform. We have identified the technical aspect of VLC as well as its research and regulatory challenges. It is argued that VLC is being considered for 6G is because it operates on a large bandwidth at Terahertz frequencies. Such an extra-wide bandwidth is expected to achieve a much higher data rate than the current 5G platform. However, methods of increasing data rates and reducing interference are among the research topics that need to be further investigated. In addition, a human-safe standard, an automotive standard, considerations for spurious RF emissions, and interference prevention on other RF spectrum bands are some of the VLC regulatory topics proposed for future study.
