LiFi, short for “Light Fidelity”, revolutionizes communication with its bi-directional optical technology, empowering lightning-fast data transfers without relying on radio waves.
Resulting from years of extensive research, LiFi 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 signal emitted by LEDs.
The signal circulates between a transmitter device (Access Point or Photonic Antenna) equipped with LED bulbs and a receiver (Key/Dongle/Receiver) 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 miniaturization of the technology, all devices (computers, smartphones, tablets, etc.) will soon integrate LiFi technology natively.
Ultra-fast, healthy, stable, and secure, LiFi is becoming a flagship technology in the world of telecommunications.
Routers, modems, repeaters, etc. WiFi requires energy-intensive electronic devices that are often left on all the time. In contrast, LiFi benefits from the energy efficiency of LED bulbs used to operate it, resulting in lower energy consumption compared to WiFi. As a result, LiFi can lead to significant savings on electricity bills.
Since the spectrum of visible light is 10,000 times wider than that of radio waves, the volume of data transported in a given time via LiFi can be much greater than via WiFi. In addition to its economic and ecological qualities, Oledcomm’s LiFi solutions are therefore particularly
efficient, and offer a speed of up to 5 Gbps, a connection speed that allows full advantage to be taken of everything the Internet has to offer (downloading, streaming, video games, online courses, collaborative tools, etc.) or to transmit data point to point.
In a world where the most sensitive business is handled electronically, cybersecurity has become a major issue to which current technologies have not provided a decisive answer. History has proven that the radio waves emitted by WiFi, because they can penetrate
walls, don’t allow governments, law firms or embassies to handle confidential files with absolute security. Our optical communication solutions, by broadcasting data via light, 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 an extremely robust connectivity solution in terms of cyber security.
Because it’s directly integrated into infrastructures, the installation of a LiFi system doesn’t involve the dangerous and impractical cable clusters that are still common. More aesthetically pleasing and safer, this installation without visible cables is also a major asset in aerospace and defense.
Indeed, it is estimated that WiFi equipment on board an aircraft weighs an average of 1.3 tons due to the shielded cables used to prevent electromagnetic interference. Without radio waves, there is no need for shielded cables, and without shielded cables, the weight of the communication system can be cut in half, resulting in significant energy and budget savings.
The omnipresence of radio waves in our daily lives is raising more and more questions. Although still undefined, the impact of near-permanent exposure to radio waves on the brain and on the development of diseases is of concern, and the need for a connectivity solution
without radio frequency pollution is being felt. Because it doesn’t use radio waves, LiFi connectivity is completely harmless, and provides a concrete answer to a central issue in the future of Internet connection.
becomes slower. Conversely, LiFi is designed to work optimally and without latency, even in areas of high congestion. In fact, each LED LiFi light bulb can provide an ultra-fast connection to all users within its coverage area. Since the densest environments are usually equipped with multiple light sources, everyone can have optimal connectivity from one of the multiple access points.
Oledcomm, a pioneer in LiFi, has developed the LiFiMAX solution, a system consisting of a transmitter device integrated into the LED bulb, called Access Point, repeaters (Photonic Antennas) and a receiver device connected to the device connected, called Key/Dongle/Receiver.
What we call 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.
The connected device to which the dongle is connected or in which the LiFi chip is integrated, when it’s located in the coverage area of the light beam, receives the data emitted by light oscillation. The reception and processing of Internet data is possible by the presence, in the
Dongle, of a photodiode that captures the light signal and a processor that translates it into a binary system to make it understandable by the computer, smartphone or tablet.
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 within a defined area. LiFi is therefore, by nature, unhackable, undetectable and non-jamming, thus ensuring the absolute security of your connectivity. To ensure additional security, Oledcomm has developed the LiFiMAXController®, a program integrated to the access point allowing the management and the complete configuration of your network infrastructure.
Education in schools is increasingly leveraging digital technology, creating new educational opportunities. Yet, concerns about the impact of radio waves on young people have led to strict regulations on WiFi usage in these environments. As an ideal and
health-conscious alternative, LiFi in schools stands out not only for its radio wave-free nature but also for its seamless capacity to accommodate multiple users simultaneously without latency. Additionally, LiFi’s space-saving feature allows easy integration into existing lighting systems.
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.
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 requirements.
In fixed environments (buildings, offices, laboratories or crisis rooms), a militarized version of LiFiMAX offers users the benefits of
mobile connectivity and avoids the ergonomic constraints of cables while maintaining optimal security.
Thanks to LiFi, mobile command posts, which often need to be relocated in an emergency, can benefit from a highly secure wireless Internet access system that can be installed and removed in just a few hours.
This LiFi equipment is also available in an embedded version to provide 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 is also a reliable and efficient way to exchange tactical data (reports, safety alerts, etc.) between a mobile boat and a control station.
