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.

A podcast on Internet of Things and Li-Fi as a warm-up for the IoT Event, 30 September on IoT and Li-Fi at High Tech Campus Eindhoven.
The Internet of Things (IoT) drives a rapid growth of the amount of data communication as tens of Billions of devices will communicate. Today’s IoT is predominantly narrowband. Yet, we also foresee increasing demands for communication at high Quality of Service, 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.

WIELAND ELECTRIC USES LIFI TECHNOLOGY IN INHOUSE PRODUCTION
Industry 4.0 requires intelligent solutions for networking machines and equipment. So-called LiFi technology is one of them. It uses the light spectrum to transfer data and is a promising alternative to WiFi and Bluetooth, because it is better protected from electromagnetic disturbance in comparison to radio waves and provides real-time capabilities in the microsecond range at data rates up to 1 Gbps. Wieland Electric in Bamberg is investigating how the technological benefits can be utilized in industrial environments. The electronics company uses the new data transmission standard in its in-house production to gain experience and include it in the development of LiFi for industrial communication.
