Voice and Data Communication Using Li-Fi
This paper focuses on developing a light fidelity (Li-Fi) based system and analyzing its performance with
respect to existing technology. Wi-Fi is great for general wireless coverage within a building, where as Li-Fi ideal for high
density wireless data coverage in confined area and for reliving radio frequency interference issues. Li-Fi provides better
bandwidth, efficiency and security than Wi-Fi. By leveraging low –cost LEDs lightings units there are many opportunities to
exploit this medium, for public internet access through street light to auto-piloted cars that communicate through their head
lights. This technology envisions a future where data for laptops, smart phones, and tablets will be transmitted in a economic
and eco friendly medium of light in room.
