visible light communication

—As part of Internet of thing networks, visible light communication (VLC) technology has excelled in recent years. When compared to traditional radio frequency (RF) technology, VLC offers the advantages of abundant and unlicensed spectrum bands, no RF-induced interference, inherent security, safety and energy efficiency, making it an excellent choice for short-range communication applications. However, the performance of VLC is severely limited under the non-line-of-sight (NLOS) links.
