Professor Harald Haas coined the term Li-Fi in 2011. The technology uses ordinary LED room lights to transmit data around the house. The disadvantage of traditional Wi-Fi routers is that multiple devices in a space can interfere with each other. Li-Fi however can use multiple lights in a room without interference. As connected devices become more popular it is predicted that Wi-Fi networks will not be able to cope with demand. Li-Fi enables devices to use their in-built stand by LED lights to transmit data. As LED lights become more popular, multiple companies are looking into using Li-Fi including, Disney Research and the Berlin-based, Fraunhofer Institute.
