LI-FI: Light and data can coexist

“Light makes the invisible visible, but it is also able to carry data and information. Objects will themselves be able to process and transmit data through the energy of light.”
Carlotta de Bevilacqua

Looking out to the future, Artemide captures the potentials of the advances allowed by technology and launches a study on LI-FI with Scuola Superiore Sant‘Anna in Pisa.

Artemide introduces the first application demonstrating the possible integration between light and data in an existing product of its collection – Demetra. Visible light is used for data transmission, showing that the LEDs that are commonly fitted on the Artemide products allow to create an infrastructure capable to handle information.

The solution developed with Scuola Superiore Sant‘Anna adds up to the wireless transmission system that is perfectly integrated with the lamp’s electronics and does not affect the optical properties or lighting performance of the appliance.

Starting from the optoelectronic components that are currently in use, a one-way Li-Fi bridge can be opened, offering very interesting options in terms of data transmission security and beyond.

Li-Fi, in fact, is a network based on luminous impulses, rather than on radio waves, and as such can only be perceived within the emission cone, but not within the perimeter of a room, however allowing performance improvements in terms of transmission power.

Moreover, this “optical wireless“ signal is not significantly influenced by other neighbouring lighting sources.

The current revolution opens up new design frontiers that reach far beyond the lighting sector and initiates a dialogue with advanced interaction systems and sensors towards new light integration opportunities in smart projects that call for the punctual and secure management of high baud-rates in private or public contexts.
