Abstract

Wi-Fi technology becomes more popular today. Every public spots and private offices have wifi because of this wireless spectrum is blocked very frequently. Due to maximum utility RF interferences are getting more common to overcome this problem light fidelity (Li-Fi) technology was introduced in the year 2011. Li-Fi is similar to other wireless communication which uses the communication medium as light. Visible light is use to transfer data between the system instead of radio signals. Li-Fi uses LED light source to transmit the data wirelessly this method is widely called as VLC (visible light communication). A stream of data transmitted in the way of pulses of light that cannot be detected by the naked eye. This paper speaks about the new vlc technology over the existing wifi technology and the challenges of new Li-Fi technology.
