People always want faster internet connection, it makes communication easy and efficient. Li-Fi wireless internet connections delivered via light. It also offers more secure communications and reduced device interference. Li-Fi (Light Fidelity) is exciting new technology similar to Wi-Fi that allows data to be sent at high speeds using visible light communication (VLC). Li-Fi offer faster broadband access in LAN (Local Area Network). Li-Fi- the new wireless technology is huge alternate of Wi-Fi which achieved wireless speed 100 times faster than the current speeds of Wi-Fi. Li-Fi format could be compared to a, very advanced, form of Morse code, like switching a torch on and off to relay a message. However, in this case flicking an LED on and off at extreme speeds can allow binary code to be transmitted.

Li-Fi which was first invented by an Professor Harold Haas of the University of Edinburgh in 2011, pioneered Spatial Modulation which is one of the principals of Li-Fi technology. It uses VLC (Visible Light Communication) to send data at extremely high speeds. This technology was able to transmit up to 224 gigabits per second.
