LIFI

The internet is one of the most important inventions of modern era. Nowadays the most trending domain in wireless communication is Wi-Fi and internet users are also being increased every year. For obtaining better speed and efficiency Li-Fi technology has evolved. Both Li-Fi and WiFi technologies are mainly used for internet based applications. Light Fidelity (LiFi) is a Visible Light Communication (VLC) based technology that making light as a media of communication replacing the cable wire communication. The main function of this technology is to transmit the data via light. This technology is idyllic for high speed wireless communication in restricted region and it offers many benefits over WiFi technology such as high bandwidth, ease of use, efficiency and safety. These systems are 100 times faster than WiFi & they also can communicate from street lights to auto piloted cars using their headlights. As the light speed is superior hence the data communication speed is also faster in LiFi. The main feature of this technology includes fully networked, bidirectional and high speed wireless.
