light fidelity

Light Fidelity Li-Fi or Light fidelity is a type of visible light communication that can be used to exchange data at a very high speed.  It uses the concept of transferring data through LED bulbs that we use every day in our life. Data transfer through this type of channel is bidirectional. The term Light Fidelity was first coined by Professor Herald Hass in 2011 in a Global Ted Talk. How does it work? Both Wi-Fi and Li-Fi use electromagnetic waves to transmit data but unlike Wi-Fi, Li-Fi uses visible light to transmit data. It uses the common LED (Light Emitting Diode) bulb to transmitRead More →
