A Survey on Visible Light Communication Standards

With the rapid increase of high-fidelity audio, video, and multimedia traffic in the new era of 5G and beyond, the current Wi-Fi solution exhibits more and more limitations. Crowded spectrum is creating realistic bottlenecks in the deployment of Wi-Fi, some of which can be well alleviated by the Light Fidelity (Li-Fi) technology. High transmission rate, wide bandwidth, no electromagnetic interference, and no health hazards have made Li-Fi an attractive technique for future smallcell communication. The emerging standardization of visible light communication (VLC) facilitates the acceleration of the development of Li-Fi technology and will eventually deliver real-world Li-Fi deployments. This article overviews the recent progress on VLC standardization and presents the mainstream VLC standards created by different standardization organizations.
