5 sur 7 Matins Tv Programme Discusses LiFi Technology with Dr Fréjus Sanya and Anaïs Nassara in Benin, West Africa
5 sur 7 Matins, Benin
On Thursday 06th October 2022, the 5 sure 7 Matins platform invited Dr Sanya Max Fréjus and Anaïs Nassara to discuss LiFi technology and their LiFi prototype. During the discussion, Anaïs stated that their first objective behind their LiFi work was to make the LiFi technology known to the Beninese population because it is not known worldwide, especially in Africa. Dr Sanya Max Fréjus explained in simple terms the principles of LiFi technology to the audience.

Below are some of the statements from the video. These statements have been translated from French to English:
Rachida: “So, the second innovation of the day is that of our friend Anaïs. And what is this innovation? Whom I call on this set and will meet us in a moment”.
Dr Fréjus Sanya : “Alright. So Anaïs worked on the first prototype. This is also the very first faucet in fact, which speaks of LiFi to interconnect terminals. I call terminals or big smartphones or downright computers to take these more familiar examples. As you know, LiFi is a concept similar to wifi. So with WiFi, we all use to share and exchange data. Okay, but it's a wireless medium that uses radio waves. So today, thanks to LiFi, with the light that surrounds us, it is also possible to always communicate, exchange, and transmit information very quickly. And it is moreover on this technology that Anaïs Nassara worked to allow us from now on to be able to exchange data between us at home or at the office. That's what she works for”.
Rachida: “Anaïs Hello, well done already for this innovation. What's the idea behind all this?”
Anaïs Nassara: “Thank you very much for this opportunity to speak. The first objective behind this work was already to make the LiFi technology known to the Beninese population because it is a technology that has emerged, I would say since 2011, but which is not known worldwide, especially in Africa. So, the first objective was really to make this technology known and also to prove, to show that in our context, the Beninese context, that such a prototype can be made in order to be able to transmit data.”
Rachida: “Okay to transmit LiFi. In fact, it allows you to communicate data simply. Is that right? In fact, we need to understand the usefulness of this innovation.”
Dr Fréjus Sanya: “LiFi actually enables communication. We already have several communication technologies based on radio frequencies, such as WiFi for example. And with WiFi, we have the ability to connect to the Internet, to be able to do our research and all that goes with it. We can actually do the same thing with the LiFi, which is not there in fact to play with and is part of the wifi, but rather comes, in fact, to support the wifi because we cannot use the wifi in different environments such as hospitals. And it's actually easier to already use the light that is already present everywhere. Especially with the evolution of the lighting fixtures we use, we have moved from fluorescent lamps to LED lamps and now with the presence of lamps using our various infrastructures and as much as possible, it is now possible to be able to use these LED lamps to transmit data.”
Rachida: “Alright. So Doctor Sanya, you are the one supervising these different students. What is the originality of Anaïs through this innovation?”
Dr Fréjus Sanya: “Thank you Rachida. In fact, you understand that LiFi is not very concrete in Benin.”
Rachida: “We didn't know. I too am discovering.”
Dr Fréjus Sanya: “Yes, so it was important to show, in fact, to make people discover what LiFi is and to show that for us, developing countries, we already have a technology which is present and which we ignore. And so, by using this technology now will allow us to go faster in the data fields. Thanks to the work of Anaïs, we proved that we could point to it and use this light for transmitting data between systems without deploying other infrastructures that will cost us dearly. Finally, in fact, to the exchange of data and the originality of her work, that is, she first understood what it means to implement, what LiFi is and the degree of agreement in the transfer of data between two computers. “
Rachida: “So. Where did this idea come from, Anaïs?”
Anaïs Nassara: “So, a year ago, actually, I saw senior student who worked on LiFi. Also at the time, and seeing his work, I was inspired. I wanted in fact to bring more to society, to bring more in fact to the continent, I would even say. So, wanting to work on this project, I became interested in this project to be able to make the first prototype in order to show Yes, we can make it. We may also have LiFi prototypes in Benin.”
Rachida: “And what stage of this innovation are we at today? Is it already popularised? What stage are we at?”
Dr Fréjus Sanya: “Yes, we have already popularised it, precisely because we are in close collaboration with a LiFi technology company which is based in Nigeria and. England and a partner in Texas, Mr Ken Peterson. They wants to help us in developing further this prototype as well as going through the various inventions that we have made recently so that our populations can have kits available. And already, we have a pilot phase of an agreement. I'm not going to lay out everything he said because it's under approval. So, that from now on, it can really only be something known by all and used by all.”
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.

LiFi Systems Reviews by LiFi Tech News
OLEDCOMM LIFIMAX KIT REVIEW - ONE YEAR IN
We reviewed the LiFiMax kit produced by the leading French LiFi company Oledcomm. We bought this LiFi kit system at the end of 2020. After over a year of use, we decided to write a review of this LiFi system. We looked briefly at the profile of Oledcomm, a brief history of the LiFiMax system, the Kit box contents, some testing and performance results of this LiFi system, the customer experience and our own verdict (the good and the bad points) of the LiFiMax kit.
