Abstract: Light Emitting Diodes (LED) are used indifferent areas of everyday life. The advantage of this device is that in addition to their lightening capabilities, it can be used for data transmissions as well. Nowadays almost all the peoples are using internet to accomplish their task through wired or wireless network. As number of users are increases in using wireless network, speed decreases. Though Wi-Fi gives us speed up to 150mbps as per IEEE 802.11n, which is not sufficient to accommodate number of desired users. To remedy this limitation of Wi-Fi, we are introducing the new concept of Li-Fi technology. Li-Fi stands for the Light Fidelity. Li-Fi provides better bandwidth, efficiency, availability and security than Wi-Fi and has already achieved blisteringly high speed in the lab. By leveraging the low-cost nature of LEDs and lighting units there are many opportunities to exploit this medium, from public internet access through street lamps to auto-piloted cars that communicate through their headlights.
Keywords: Li-Fi, Wi-Fi, high-brightness LED, photodiode, wireless communication.
