Review Paper On Lifi Technology

Abstract

Light Fidelity is the abbreviation for Light Fidelity. The concept is relatively new, having been introduced by German scientist Harald Haas at the 2011 TED Global Talk on Visible Light Communication (VLC). Li-Fi is a wireless optical networking system that transmits data using light emitting diodes (LEDs). Visible light communication (VLC) technology is referred to as Li-Fi. 802.15.7. IEEE 802.15.7 is a wireless communication technology based standard that is high-speed, bidirectional, and fully networked, akin to Wi-Fi's IEEE 802.11. The focus of this paper is on Li-Fi, its applications, features, and comparisons to other technologies such as Wi-Fi. WiFi is widely used for general indoor wireless coverage, while LiFi is most suitable for high-density wireless data coverage in small spaces, especially for applications with radio interference problems. Therefore, these two technologies can be seen as complementary. Li-Fi outperforms Wi-Fi in terms of bandwidth, efficiency, connectivity, and security, and has already attained rates of over 1 Gbps in the lab. There are numerous chances to leverage this medium by leveraging the low-cost characteristics of LEDs and lighting components. Li-Fi refers to the transmission of data via light, which is accomplished by removing fibre from fibre optics and transferring data through an LED light bulb.
