New Epoch of Wireless Communication: Light Fidelity

Abstract

We have Wi-Fi hotspots at home, coffee houses, hotels, airports and even cities and the Wi-Fi network system is constantly expanding. Due to this, Radio spectrum is getting clogged day by day and demand for wireless data is increasing exponentially every year. Everyone wants to use wireless data but capacity is drying up. Wireless radio frequencies are getting higher, complexities are increasing and RF interferences continue to grow. In order to overcome this problem in future, light –fidelity (Li-Fi) technology came into existence since 2011. Li-Fi is a wireless communication system in which light is used as a carrier signal instead of traditional radio frequency as in Wi-Fi. Li-Fi is a technology that uses light emitting diodes to transmit data wirelessly. Visible light communication (VLC) uses rapid pulses of light to transmit information wirelessly that cannot be detected by human eye. This paper will focus on Li-Fi technology over Wi-Fi technology and challenges for the new VLC technology.
