According to Wikipedia: Li-Fi (ˈlaɪfaɪ; short for light fidelity) is wireless communication technology, which utilizes light to transmit data and position between devices.
In technical terms, Li-Fi is a light communication system (hence based on photonics) that is capable of transmitting data at high speeds over the visible light, ultraviolet, and infrared spectrums. In its present state, only LED lamps can be used for the transmission of visible light.
In terms of its end use, the technology is similar to Wi-Fi – the key technical difference being that Wi-Fi uses radio frequency to transmit data.

The Internet of Things (IoT) drives a rapid growth of the amount of data communication as tens of Billions of devices will communicate, with widely varying communication requirements. Today’s IoT is predominantly narrowband. Yet, we also foresee increasing demands for high speed communication at with critical Quality of Service requirements, such as guaranteed high bit rates at low latency. A wide range of future IoT applications, i.e. flexible manufacturing, augmented reality and autonomous cars require the exchange of sensor and video data, processed in the cloud, while doing real-time remote control of autonomous devices.
