Oledcomm Presented Their New Gigabit Optical Front End (OFE) Chip At The MWC (Mobile World Congress) Barcelona 2021
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.
MWC Barcelona 2021
MWC Barcelona (formerly Mobile World Congress) is the largest mobile event in the world as well as the meeting place for the leaders of the mobile and related industries. The event is held in Barcelona, Catalonia, Spain at the Fira de Barcelona Gran Via, usually in February or early March. It is attended primarily by device manufacturers, network equipment providers, representatives of wireless carriers, and the press, among others. Its annual attendance is generally around 100,000 people, while mobile phone manufacturers often use the conference to unveil upcoming devices.
GSMA has extended the MWC brand to two other trade shows in Shanghai, China (MWC Shanghai) and Los Angeles, United States (MWC Los Angeles, formerly MWC Americas), but the brand remains most synonymous with Barcelona event.
MWC Barcelona attracts some of the most influential decision-makers in the world. It’s where 2,400 leading companies and trailblazers share the latest topics relevant to the future. And the best place for networking opportunities with mobile and tech industry influencers.
During the Mobile World Congress, which took place from June 28 to July 1 in Barcelona (Spain), Oledcomm presented its new Gigabit Optical Front End (OFE) chip. It integrates directly into mobile devices to allow them to exchange data by light thanks to Li Fi (Light Fidelity) technology.

This integrated circuit makes it possible to insert Li Fi functions directly into mobile devices, and in particular smartphones for which the dongle is not suitable. "It's a revolution," proclaims Benjamin Azoulay, president of the company. This places us among the only two companies in the world to have miniaturized LiFi technology. " The competitor in question being the Scottish pureLiFi.
Li Fi transmits information at high-speed thanks to the ultra-fast flickering of light sources. Manufactured by STMicroelectronics, the Gigabit OFE chip has a light source which can be a small VCSEL laser (for vertical-cavity surface-emitting laser) - the same type as those found in some smartphones for facial recognition - or a light-emitting diode (LED). The light is received by two photodiodes and an ASIC (Application-Specific Integrated Circuit) microprocessor processes the transmitted and received signals.
Thanks to his chip, Mr Azoulay imagines a future for LiFi similar to that of WiFi: “Before manufacturers integrated it into their devices, WiFi was also obtained with USB keys. We have engaged in discussions with major manufacturers of mobile devices. "
Applications range from the general public to education, including industry and defence. “Let's be clear, LiFi will never replace WiFi, admits Mr Azoulay, however. But it has its place in niche markets which already represent significant volumes. For now, we are targeting more professional applications. The general public will come later. » Two equipped devices can exchange data for example. They can also communicate with a LiFi router positioned on the ceiling of a room. “Education is an application area in which we believe a lot,” says Mr Azoulay, who imagines student tablets connected to routers on the ceiling of the classroom.

Because light does not pass through walls, Li Fi offers more security when transmitting data. A weight advantage over WiFi which nevertheless wins from the point of view of speed. While Oledcomm announces that it will reach a speed of 1 Gbps (gigabit per second) over a distance of 1 to 5 meters, WiFi 6 theoretically allows reaching a speed of 10 Gbps. On the other hand, LiFi outclasses Bluetooth for the exchange of data between devices: "Li Fi speed is about a thousand times higher," says Mr Azoulay. LiFi also makes it possible to avoid the presence of radiofrequency waves in places where they are sometimes unwelcome - especially in classrooms or certain industrial environments.
What is Li Fi?
Li-Fi, 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 Li-Fi 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 Li Fi work?
Li-Fi is a high speed, bidirectional, and fully networked wireless communication of data using light. Li-Fi 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.
Li Fi Benefits
The primary benefits of Li-Fi 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 Li-Fi 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.
