Let there be light—for internet access, that is.

French luminaire manufacturer Lucibel has rolled out Light Fidelity (LiFi), a communication technology through modulated LED light that enables data exchange between a specific LED lighting fixture and a computer, making Internet access possible.

The communication technology through light has existed for several years but only in low speed unidirectional version (visible light communication) which enables the deployment of indoor geolocation applications, in particular in shop and museum sectors.

The LiFi solution by Lucibel enables the deployment of a complete wireless network through a bidirectional transmission of 42Mbps. The system requires a RJ45 wire to be connected to the lighting fixture, which, in turn, becomes a head end, and then a LiFi key is connected to the computer USB port.

Each LiFi luminaire can serve several LiFi stations simultaneously. The function allows users to automatically have a stable connection from a lighting fixture to another.

In addition to traditional power supply, the luminaire is optionally compatible POE/POE+ and High Power POE in order to minimise the necessary wiring for the deployment of a LiFi network infrastructure.
