Data Transfer using Li-Fi Technology

Li-Fi means light fidelity y. It is the newest technology for wireless data communication. It is similar to Wi-Fi technology. It is often frustrating when the speed of data transmission is slow, which leads to more processing hours using other wireless transfer techniques. Wi-Fi provides us speed about 150 Mbps by using IEEE 802.11(n) but still it is not able to fulfil the requirement of user because of such reason we introducing the new technology such as Li-Fi. There is very high data transfer rate in Li-Fi technology. Li-Fi technology is firstly introduced by a German physicist Harald Hass. According to him Li-Fi technology provides more speed than Wi-Fi technology. In Li-Fi technology LED is used for transmitting the light signal. According to changes in light intensity of LED we get the appropriate data at the receiver. Light Fidelity– IEEE 802.15 Standard is high-speed, bidirectional, networked and mobile wireless communications using light. It uses concept of visible light communication for data transmission. Li-Fi is an emerging technology that could see specialized LED (Light Emitting Diode) light bulbs providing low-cost wireless internet connectivity almost everywhere. Li-Fi is the future of high speed data transmission in wireless communication technology.
