French LiFi pioneer Oledcomm has doubled the speed of its second generation light-based communications technology, aiming it as transportation and industrial automation

LiFiMAX2G, launched at CES 2023 this week, provides a 2Gbit/s secure bidirectional connection over a distance of up to 5m for a greener alternative to radio waves and cables with lower energy consumption.

The company sees LiFiMAX2G as particularly suited for subways, trains and any vehicle that needs to download terabytes of images and video data in less than 20 seconds as well as for industrial Industry 4.0 applications in augmented reality, IoT or M2M.

The wireless optical technology, based on infrared LEDs, is as fast as Gigabit Ethernet, more secure than WiFi, and as small as a smoke detector. Using light avoids interference compared to other radio wave-based communication modes allowing devices to exchange data safely at any time.

“The dizzying growth in the amount of data collected in mobility situations and the increase in multimedia flows require a reliable and uninterrupted communication standard for all, especially in transport and factory 4.0. We are proud to contribute to the development of these new standards,” said Benjamin Azoulay, President of Oledcomm.

The company is a spin off from the University of Paris-Saclay, backed by the European EIC accelerator programme and has a strong technology leadership in LiFi, with more than 33 patents. Last year it launched a dedicated ASIC for the LiFi technology.

The company was demonstrating industrial LiFi connected augmented reality (AR) applications as well as V2I (Vehicle to Infrastructure) connection. Since 2020, the first generation LiFiMAX technology has been installed and tested in more than 800 projects worldwide and has been validated by Orange for Cybersecurity.
