Li-Fi Technology - Data Transmission Through LED
Li-Fi means Light-Fidelity. Li-Fi technology, Introduced by the German ScientistÃ¢â‚¬â€Harald Haas, It provide data transmission through LED. Variation in intensity of LED is faster and it can not be recognized by human eye. The moto behind this technology is focusing on Li-Fi system and compare its result with existing technology. Wi-Fi is used to cover small Geographical area with low data rate whereas Li-Fi is used for high data rate transmission in confined area and no radio interference issue. In this technology we achieved better bandwidth,security,efficiency and availability than Wi-Fi. .the cost of LED is low hence enhanced the system of Li-Fi technology. This technology is very important for future to transmit the data in a room for Laptops,Smart Phone and Tablets.
