A method of transferring data which uses light as opposed to Wi-Fi which uses radio waves. It requires a light transmitter and compatible receiver. Under optimum conditions it can reach speeds of 10Gbit/s. However it is more applicable to stationary systems as it requires line of sight to be fully effective.
Using light emitting diodes Li-Fi transmits by simple flickering for the ones and zeros of information. It has a high potential for use in any industry where Wi-Fi may interfere with radio waves or as a security measure since it does not broadcast over an area.
