Basel company brings Internet over the light

LiFi is a new technology that uses normal LED lights for data transmission. The Swiss company Regent Lighting has already started with first pilot projects.

Lights can do so much more than just brighten a room. The spectrum of visible light is huge, for example 10'000 times larger than that of the entire radio frequency. This bandwidth of light is currently not used. But that could change in the next few years, also thanks to Regent Lighting from Basel . With over 600 employees, the company is one of Europe's leading lighting manufacturers over one hundred years of tradition .

Actually, LiFi (Light Fidelity) is not a new invention. Back in 2011, a German researcher demonstrated how data can be transmitted via light. For this purpose, an LED is quickly switched on and off - imperceptible to the human eye. To make a luminaire LiFi-capable, the luminaire requires a modem, which is connected to the Internet via Ethernet cable. For receiving Internet via light, a photocell is needed. To return data, infrared is used.

LiFi has not made it out of the research lab so far, and prototypes are currently being worked on all over the world. For example, Microsoft has installed LiFi in a research center in France. NASA wants to test an application in space probes.

Regent Lighting integrates LiFi into normal lights
Regent Lighting is at the forefront of development in a start-up style. At the Ineltec, the Swiss trade fair for intelligent building technology, the company from Basel showed LiFi for the first time in September, integrated in a luminaire from the normal range. "Now we are planning initial pilot projects in which we serve our customers with an entire LiFi lighting system," says Fabian Gerschwiler (30), Product Manager Connected Lighting.

The system is currently achieving a download rate of 20 Mbps and an upstream of 5 Mbps in industrialized solutions. That's enough to stream Youtube films, but is still well behind conventional WLAN technology. Although you can use normal LED lights, but they must be at least 1000 lumens and not higher than three to five meters hanging.
