Wired or wireless network of internet has been in vogue to carry on our work. Network speed is clearly related to the number of users, it degrades with the increase of users. The Wi-fi speed upto 150 mbps fails to meet the need of users. To counter it Li-fi is introduced. The same idea called D-LIGHT also used in infrared remote controls produces the data rates faster than average broadband connections. Li-fi the Light Fidelity, as coined by German physicist Harald Hss transmits data through illumination. This paper discuss will Li-fi system in detail. Wi-Fi provides connectivity within the buildings, whereas Li-fi is used for coverage in captive area. Li-fi is better than Wi-Fi in efficiency, availability and security. Li-fi can be used for public internet access through street lamps and auto piloted cars. Hass visualizes the working of phones and laptops through light in the room.
