Abstract: Wi-Fi technology is the most popular technology to connect a network easily. To overcome the speed constrains of Wi-Fi technology, a new technology called Li-Fi was introduced in 2011 by Harald Haas who was a germen physicist. Li-Fi technology throw out the optic fiber by sending the data through Light Emitting Diodes, which can perform a transmission of 10 megabits per second . Normally visible light communication is done using LED’s, but this work demonstrates the data transfer method using single LASER light and a photodiode by using serial communication. A study on VLC was done and most efficient method has been used. Visible light communication system is more useful in the areas where the radiations and OFC are prohibited.
