Light-Based Wireless Communication and Its Uses

Li-Fi, or Light Fidelity, is a new and emerging advanced visible light communication technology that offers high speed data transfer similar to wi-fi and for this reason, Li-Fi is also called Wireless Fidelity. IEEE802.15.7, which is a standard that according to IEEE also supports a network topology and wireless communication similar to Wi-Fi and is high-speed and widely useful which is provides portability. Li-Fi technology was invented by Harald Haas, a German scientist whose novel idea was first suggested in a TED Global Talk on July 10, 2011, as the possibility of visible light communication (VLC) Li-Fi. In essence, this VLC technology described by Haas represent a breakthrough in the development of optical wireless networks based on the utilization of light emitting diodes (LEDs) for transmitting data.
