Fibre-optics without wires is becoming reality. At OFC 2017, the Dresden Fraunhofer Institute for Photonic Microsystems (IPMS) will demonstrate a prototype Li-Fi communications module that uses infrared light to transmit data over company networks.
Originally envisaged as light bulbs that could also act as wireless routers, Li-Fi technology can deliver signals over distances of up to 10m and at speeds of one gigabit per second or more.
