What is LiFi?

Introducing Light Fidelity (LiFi) technology, quite literally a beacon of innovation!

Light communication harnesses light to create a wireless connection that promises unparalleled speed and reach. Resulting from years of extensive research, light WiFi is an innovative technology for converting light into data. The data transmission is carried out by the modulation, invisible to the naked eye, of a light emitted by LEDs.

The signal circulates between a transmitter device (Access Point or Repeater Antenna) equipped with LED bulbs and a receiver (Dongle) connected to the devices. Though the use of an external receiver is still required for most devices, Oledcomm has created the first casing for tablets integrating a LiFi receiver. Thanks to the compact nature of the technology, which was also pioneered by Oledcomm in 2021, all devices (computers, smartphones, tablets, etc.) will soon be able to integrate LiFi solutions natively.

Oledcomm recognizes the advantages of LiFi Internet extend far beyond conventional wireless systems. Ultra-fast, healthy, stable, and secure, LiFi is becoming a flagship technology in the world of telecommunications.

The advantages of LiFi

LiFi solutions provide up to 50% in Energy Savings compared to Wifi

Routers, modems, repeaters and other traditional WiFi equipment is bound up in energy draining, physical assets. In contrast, light communication uses energy efficient LED bulbs and doesn’t need wires to operate, resulting in lower energy consumption compared to WiFi. As a result, LiFi can lead to significant savings on electricity bills.

The most striking feature of LiFi technology is its remarkable speed, which operates on the spectrum of visible light that’s 10,000 times wider than that of radio waves. Unlike WiFi, which operates on radio frequencies, light fidelity (LiFi) utilizes light waves, enabling data transfer at unprecedented rates. Offering speeds up to 5Gbps, light communication can revolutionize various sectors that require high-speed wireless systems, including telecommunications, healthcare, and transportation.

Total Security: LiFi Distance Range & Data Partitioning within the Broadcasting Area

In a world where the most sensitive business is handled electronically, cybersecurity has become a major concern to which current wireless technologies have not provided a decisive solution. Our optical communication solutions, by broadcasting data via light communication, don’t go outside a defined area and allow a connection strictly limited to the area in which they are installed. In essence, LiFi is not interceptable, and provides extremely robust and secure connectivity with regards to cyber security.

LiFi Distance Range: Reaching far and wide effortlessly

Oledcomm’s LiFi solutions transcend the limitations of traditional wireless networks by prioritizing accessibility and reducing the necessity for physical hardware or impractical cable clusters. Since WiFi signals are confined within a limited range, often necessitating the installation of multiple access points for comprehensive coverage, LiFi offers broader reach with fewer infrastructure requirements through LiFi technology.

Radio-Wave Free: LiFi Solutions for Non-Harmful Data Transmission System

The omnipresence of radio waves in our daily lives is raising more and more questions on its impact on the brain and development of diseases. The near-permanent exposure to radio waves has accelerated the need for a connectivity solution devoid radio waves. Because LiFi communication doesn’t use radio waves, it is completely harmless, and provides a concrete answer to a central issue in the future of Internet connectivity.

Utilizing an Expansive LiFi Bandwidth for Uniform, Latency-Free Light ommunication

In addition to its speed and reach, light fidelity technology sets itself apart through its versatile utilization of available bandwidths that have been previously overlooked. Unlike WiFi, which only operates within crowded radio frequency bands, light WiFi or light communication leverages the vast spectrum of visible light, infrared, and ultraviolet wavelengths. By utilizing multiple wavelengths simultaneously, LiFi internet networks can mitigate interference and congestion, delivering reliable connectivity in high demand and high density environments.

Access point

LiFi signal transmission

An Access Point is a LiFi router connected to the Internet through an RJ45 Ethernet cable with PoE capability, integrated in a LED light bulb. The Access Point receives the information from the network as an electrical signal, and then it’s translated by the switching of the LED bulb. The bulb emits a light beam whose intensity varies tens of thousands of times per second, so fast that this oscillation is perfectly invisible to the naked eye.

LiFi use cases

Military Internet

Defense & Security

Oledcomm LiFi also has significant benefits for the defense industry, which is still forced to access the Internet via bulky cable systems to meet its demanding cybersecurity needs.

In fixed environments (buildings, offices, laboratories or crisis rooms), a militarized version of LiFiMAX offers users the advantages of mobile connectivity and avoids the ergonomic constraints of cable while enjoying optimal security.

Thanks to LiFi, mobile command posts, which often have to relocate in an emergency, can enjoy an ultra-secure wireless Internet access system that can be deployed and redeployed in just a few hours.

This LiFi equipment also exists in an embedded version to equip vehicles or any other mobile object with a reliable, fast, secure and interference-free connection.

In addition to the Internet connection, LiFi also enables point-to-point communication,
with ultra-fast data exchange. It’s also a reliable and efficient way to exchange tactical data (reports, security alerts…) between a mobile boat and a control station.


As connected devices continue to shape the industry of the future, the aerospace industry faces a major obstacle: interference from these devices on critical cockpit equipment, which can hinder the proper functioning of the

Cybersecurity is at the heart of our approach. Rather than using radio waves, LiFi uses the near-infrared light spectrum to transmit and receive data. Light has a significant advantage – it doesn’t pass through walls. The use of light to exchange data therefore makes it possible to physically secure connectivity

Industry & Transportation

Wireless, interference-free and allowing highly accurate geolocation, LiFi technology has many advantages for the transportation and industrial sectors. While its merits were already being touted in the aeronautical and aerospace industry, it’s equally suited to land-based transportation systems such as trains, city transit systems and cars. The development of LiFi in the industrial and transportation sectors is still in its infancy, but we can already imagine multiple ways to benefit from this technology. For example – fast and stable Internet connection during trips, warning systems in case of imminent collision, exchange of information on traffic or road conditions, equipment of traffic lights to make traffic flow more smoothly, suggestion of routes in real time, etc.
