L’école Communale D’Aubange
Students from the L’école Communale D’Aubange were able to test LiFi technology in their classrooms.
Several Walloon and Brussels schools already have it. Close to a light source, it can transmit information. For LiFi to work, you have to install infrared access points on the ceiling connected to the LED bulbs and LiFi receivers (LiFi USB Dongles) on each tablet. Cédric Gelpi of LiFi solutions ASBL states the following: "It's faster, more stable and more secure, but it also consumes less energy than WiFi".
Convinced students
The students have to get to grips with the technology but in the end, it doesn't change their habits so much with WiFi, but they seem convinced: " We can work in another way and it's better for our health ", " With WIFI, waves are not good for our body. LiFi is by light and therefore it is better for us ", adds another student. In any case, the mayor of Aubange François Kinard also seems won over: " We would like to develop the technology on a larger scale in the territory after this first test". In administration buildings, schools or even through public lighting, there are many possibilities for installing LiFi technology. Four schools are already using the system, installed by the non-profit organization LIFI solution in Wallonia.

LIFI SOLUTIONS ASBL
LiFi Solutions ASBL offers a comprehensive approach that includes support for the purchase and installation of LiFi equipment in schools or any other establishment and the supply of connected tablets. LiFi Solutions ASBL have a partnership with Signify to bring LiFi kits in classrooms.
According to their website, LiFi Solutions ASBL states that they have installed LiFi equipment in Classrooms in Wanze, Flobecq, Uccle and Aubange.
Wanze
“We were the first in Belgium to believe in this new technology which protects our students and our teachers from the potentially harmful waves of WIFI.
In 2019, we installed our first pilot school in LIFI (Bas-Oha) and are in the process of thinking about the complete deployment of a class in order to put the students in the right conditions to test all the advantages of this technology” explains Christophe Lacroix , Mayor of Wanze
Brussels
“Our school offers specialized mixed secondary education. As Director, I attach particular importance to the quality of our infrastructures, in terms of functionality, safety, ergonomics and environment. When the company Aromatik Studio from Nivelles offered to test Signify's LIFI solution in one of our classrooms in Uccle, without any form of commitment, we didn't hesitate for a second! A stable and secure Internet connection is essential in class, since some students are already using connected interactive tablets. This technology would also allow us to avoid having to subject our students to potentially harmful waves, as could be the case with WIFI,” explains C Watterman, General Manager of Groupe La Cime.
Flobecq
“We are particularly grateful and proud to be able to test the use of this new technology that is Li-Fi from Signify in our establishment. Today's digital development is an integral part of learning tools, but the harmlessness of its devices is often questioned. In this context, Li-Fi, which is a non-invasive technology, has the notable quality of not producing any electromagnetic waves potentially harmful to children's health,” explains Damien Rubay, School Director at Flobecq.
“The online learning tools available today offer students and teachers access to many educational modules all over the world; these are essential to achieve our objective: to help our students to master and use the various tools correctly and safely (tablets, laptops) and to support them within the framework of the “digital school” project. It is very important for the schools in our municipality to have innovative, powerful, stable connection solutions adapted to the needs of the schools,” explains Philippe Mettens, Mayor of Flobecq.
What is LiFi?
LiFi, also known as "Light Fidelity" is a wireless optical networking technology, which uses light-emitting diodes (LEDs) to transmit data. In 2011, professor Harald Haas made a LiFi demonstration at the TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC).
VLC uses light as a medium to deliver high-speed communication like Wi-Fi and complies with the IEEE standard IEEE 802.15.7. The IEEE 802.15.7 is a high-speed, bidirectional, and fully networked wireless communication technology-based standard similar to Wi-Fi's IEEE 802.11.
How does LiFi work?
LiFi is a high speed, bidirectional, and fully networked wireless communication of data using light. LiFi constitutes of several light bulbs that form a wireless network.
When an electrical current goes through to a LED light bulb, a stream of light (photons) emits from the lamp. LED bulbs are semiconductor devices, which means that the brightness of the light flowing through them can change at extremely high speeds. The signal is sent by modulating the light at different rates. The signal can then be received by a detector that interprets the changes in light intensity (the signal) as data. Also when the LED is ON, you transmit a digital 1, and when it is OFF, you transmit a 0.
LiFi Benefits
The primary benefits of LiFi are as follows:
• Security: Provides entirely secure access. Where there is no light there is no data.
• Safety: Does not produce electromagnetic radiation and does not interfere with existing electronic systems.
• Localisation: Allows localisation due to the small coverage area of LiFi access point - localisation can be used for very precise asset tracking.
• Data density: Provides ubiquitous high-speed wireless access that offers substantially greater data density (data rate per unit area) than RF through high bandwidth reuse.
