Lifi (Light Fidelity) Technology For Future Wireless Communications
Light-Fidelity, For the fast sophisticated technology and electronicgadgets and to improve effective use of speed
of light a new technology is developed which is called as LIFI. LIFI is a modern technology which is used in succession with
WIFI technology. LIFI uses LED lights for higher data rate and good flexibility through Wi-Fi. As light is everywhere, using
speed of light as the mode of transmission. The transfer of data through light fidelity is in bits and is comparatively
much faster than Wifi. Dr. Herald at the University of Edinburgh, UK, proposed the proof of Light Fidelity (Li-Fi). Li-Fi
is the transmission of data through speed of through LED light.In this paper, we focus the key technologies foranalyzing Li-
Fi and present situation of LiFion each aspect, such as customer satisfaction, resource allocation.
