Chantefleur, The First Nursery School in Paris Equipped with LiFi, Feedbacks Their Experience with Oledcomm LiFi system

Chantefleur Nursery School

Oledcomm released a video showcasing the positive reviews of staff at Chantefleur school in L’Isle-Adam. Chantefleur is the First Nursery School in Paris Equipped with LiFi technology. The nursery school reviewed their experience of using LiFi in the classrooms. Stephan Gardel, IT Manager in L’Isle-Adam, said:

“So, Oledcomm recommended and offered me their LiFi solution. It was perfect timing since I was looking for different solutions. Eventually, we went ahead with the LiFi solution, which fulfilled our requirements, especially regarding safety for children and the somewhat ecological aspect. Of course, I learned more about the technology. It consumes about 50% less electricity, so it's energy efficient.”

Benjamin Azoulay, CEO of Oledcomm, said:

“It's a breakthrough technology because instead of using radio frequency waves, we use photon light to connect to the internet. It's completely new. It uses LEDs, a bit like Morse code, that is to say that we will flash the LEDs at very high speed at 30 MHz, 30 million times per second in order to be able to connect to the Internet.”

Florence Berckelaers, Headteacher and Director at Chantefleur school, stated that “With LiFi, we were able to set up educational activities with the little ones, with the very young, which we haven't done until now. We were able to set up activities that allow direct communication via the Internet, via the Benelux, from the school, with the parents or with other classes or with other schools. And since the connection is very reliable and very fast, that opens up fields of activities that we didn't have until then and which are very, very interesting.”

Chrystelle Lacroix Touroude, teacher at Chantefleur school, said in her statement:

“The tablet allows fairly simple manipulation of the software and distribution to other classes as well. It makes it possible not to have cables and to allow other classes to have access to this kind of software quite easily. It allows some children in difficulty not to have this barrier of the sheet or let's say that it diversifies our supports. So, it's not the only support in kindergarten, it shouldn't be the only support, but it's a very interesting tool for us and for the children.”

Stephan Gardel, further stated:

“The installation went well, there were no issues. Once the wiring was stretched, it came with the accessories and we installed them. It happened very simply. After 12 o'clock, we equipped two rooms to start and it worked right away. So, I am satisfied. We work in complete transparency, that's important. And there is a certain reactivity, indeed. And this is important. I like to work only with companies, with people I work with, who I can trust. In fact.”

Sebastien Poniatowski, Mayor of L’Isle-Adam, concluded with the following statements:

“Our city's responsibility, on the other hand, is to equip our schools so that children can teach, learn and grow in the best possible conditions. So, it's both the buildings, the schools, but it's also what there is, the equipment and the technology that is offered to the children. So, the challenge for us is above all to offer the best to children and above all to give them a setting that can be a fulfilling setting for them.”

Oledcomm

Oledcomm designs and develops LiFi network interface devices that enable high-speed wireless data communication. It also serves LiFi equipment in the telecom, datacom, personal electronics, and industrial markets. The company’s product portfolio includes hubs, routers, switches, adapters, drivers, power supplies, and more.

Oledcomm was founded in 2012 and is based in Paris, France. Oledcomm's adventure began in 2005 in the research laboratories of the University of Versailles-Saint-Quentin with the first work on communication by visible light.

Following years of research & development and a passion for innovation, Oledcomm became the pioneer of LiFi (Light Fidelity) solutions and innovation on a global scale.

Based in the Paris region, Oledcomm employs around 20 people and designs complete solutions for LiFi operation, including microcontrollers, LiFi photoreceivers and software platforms.

Today, after more than 28 patents, 15 years of R&D, over 500 trusted clients and several awards, Oledcomm is pursuing a strong mission: to transform the 14 billion points of light in the world into a powerful communication network.

Li-Fi Conference 2022

The Li-Fi Conference 2022 Edition was a great success. Li Fi Tech News will very soon write articles on the topics treated at the Conference.

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.
