Fraunhofer HHI’s has developed an optical wireless communication (OWC) technology known as Li-Fi and, with industry partner Sangikyo Corp., has launched the first Li-Fi device in Japan. Dubbed the LED Backhaul, the device is an LED-based optical link, initially introduced as a 4K/8K Video Relay that can achieve data rates between 100 and 750 megabits per second.
“One of Sangikyo’s new initiatives is the collaboration with Fraunhofer HHI. We have worked with Fraunhofer HHI to advance the joint development of high-speed wireless communication with LED light and have attained a realistic application. In future, LED backhaul® will be standardized by IEEE 802.15.13 and by international standardization activities of the Fraunhofer HHI,” says Yasukazu Sengoku, COO Sangikyo.
“We are developing the communication technologies of the future and are pleased that the new wireless system with LED light, which was brought to the market in cooperation with Sangikyo, will be used on the Japanese market. We will continue to work with Sangikyo and develop a wide range of high-speed wireless systems with LED light," says Prof. Ronald Freund, Head of the Photonic Networks and Systems department at the Fraunhofer HHI.
Optical wireless transmission is a future-oriented technology for fixed and mobile wireless optical communication over comparatively short distances. Possible applications are wireless backhaul and fronthaul for 5G, wireless communication for industry 4.0 as well as in indoor areas alongside Wi-Fi and LTE, for instance in conference rooms.
