Li-Fi is a bidirectional, high speed and fully networked wireless communication technology similar to Wi-Fi. A new technology , LiFi, could one day offer internet speeds one hundred times faster than the WiFi we use today . Scientists have achieved speeds in the lab of up to 224 GB per second.
That’s the equivalent of downloading 18 movies in the blink of an eye.LiFi, or light fidelity, is now moving to trials in the real world, with office tests in Tallin, Estonia achieving speeds of 1 GB per second, 100 times the speed of traditional WiFi.
It is wireless and uses visible light communication or infra-red and near ultraviolet (instead of radio frequency waves) spectrum, part of Optical wireless communications technology, which carries much more information.
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.
Like Wi-Fi, LiFi is wireless and uses similar 802.11 protocols; but it uses visible light communication (instead of radio frequency waves), which has much wider bandwidth.
