Full form of Li-Fi is Light Fidelity. It is invented by professor/engineer Harald Hass in year 2011. Who is also the CEO of Pureli-fi. It provides wireless network like Wi-Fi.

Wi-Fi is based on Radio frequency. opposite of it,Li-Fi is based on light. Who is able to transfer data 100 times faster than Wi-Fi. To transfer data in Li-Fi technology it use LED bulb it means in this technology data transfers through Visible Light Communication(VLC). It works similarly like your television remote.

Li-Fi technology has an advantage that it do not blocks any other radio signal. That’s why it is used in those places where radio signal blockage is mostly caused like aeroplanes. It also has a disadvantage, since it is based on light it is unable to pass over a wall or some solid substance like Wi-Fi.
