Communication (VLC) or so called Light Fidelity (Li-Fi) is a new technology for wireless connectivity that uses optical energy for illumination and data communication at the same time. This technology uses white LED lights to send information to mobile users. It is a bidirectional, high-speed and fully networked wireless communication technology similar to Wi-Fi. It is a subset of optical wireless communications (OWC) and could be a complement to RF communication (Wi-Fi or cellular networks), or even a replacement in contexts of data broadcasting. Because of its unique features, VLC offers many advantages over the conventional Wi-Fi systems. Security, human body safety and RF interference free are some of these advantages that make VLC a better candidate in many applications. In this talk, we review the potentials and applications of VLC technology and discuss the limitations and challenges it is facing.
