Li-Fi

Li-Fi 

Li-Fi (Light Fidelity) is a bidirectional, high speed and fully networked wireless communication technology similar to Wi-Fi. Coined by Prof. Harald Haas, Li-Fi is a subset of optical wireless communications (OWC) and can be a complement to RF communication (Wi-Fi or Cellular network), or a replacement in contexts of data broadcasting. For now, long restricted to the academic domain, Li-Fi, a light-based data delivery method is suddenly getting all sorts of attention. An Estonian startup Velmenni recently tested an commercial implementation and found it to be superior to Wi-Fi in almost every way – except as something you and I will probably ever use. Velmenni’s technology, called Jungru, uses an LED bulb and transmits data at gigabit speed. It has a theoretical speed of 224 gigabytes per second, the BBC reported. While the Jungru product is commercially viable, it is still based on what seems to be a laboratory-grade MATLAB and Simulink setup paired with photodiodes as opposed to a final product which must transmit data in real world environments full of light pollution and other variables.
