There are 6 types of directional product prototypes.
LiFi (light fidelity) technology can be seen in optical communication technology (Visible Light Communication, VLC), which refers to the use of light in the visible light band as an information carrier without the need for optical fiber and other transmission channels. Medium, a communication method that directly transmits optical signals in the air. The advantages of this technology are energy saving, environmental protection and strong anti-interference. With the popularity of LED lights, the technology of using LED lights for visible light communication has gradually developed.
Minghua Zhixun (Tianjin) Technology Co., Ltd. was officially registered on on February 9, 2018, and is a transformation project for visible light communication and other optical communication related research projects of the Department of Electronic Engineering of Tsinghua University. Song Jian, a core member of the team, is a professor and doctoral supervisor of Tsinghua University. He is currently the director of the Digital TV Technology Research Center. His main research areas are digital multimedia transmission, power line communication, visible light communication, and broadband wireless communication technology.

from Public Information learned that the company’s business positioning mainly includes two aspects, one is LED-ID indoor positioning, which solves indoor positioning problems, low power consumption and high accuracy; the second is the Internet of Things data transmission, providing High-quality network access and data transmission services.
Given the indoor environment cannot use GPS positioning, identifying this environment technology is usually the deployment of wireless access points. As more LED lights are installed in the buildingAnd visible light communication can accurately locate indoor locations, and visible light communication has become a substitute for wireless access points. The number of LEDs in a typical building is usually more than 10 times the number of wireless access points. The high density of LEDs ensures accurate positioning of mobile devices, and the energy efficiency of LED lighting networks will promote the growth of the location-based services market.
It is understood that the company has currently developed 6 directional product prototypes, namely power line carrier + visible light real-time two-way voice system; visible light real-time monitoring system for industrial applications, and long-distance two-way voice / video communication system; Smart street light system based on visible light; one-way video broadcasting system; VLC access control and indoor positioning.
The latest research report from Grand View Research shows that the global visible light communication (VLC) / Light Fidelity (Li-Fi) wireless optical communication market is expected to reach 101.3 billion US dollars by 2024. In a report by Technavio, the global visible light communications market can be segmented into: indoor networking, location-based services, intelligent transportation systems, flight communications and entertainment, and underwater communications. In the future, this technology can be combined with communication technologies such as WiFi and cellular networks in the Internet of Things, and is used in many fields such as hospital medical, electronic products, advertising display, traffic control, indoor positioning, and aircraft underwater communications.
Technavio mentioned that the leading manufacturers in the field of visible light communication systems include: pureLiFi, Oledcomm-France LiFi, Nakagawa Laboratories, Outstanding Technology, LightPointe Communications, and fSONA Networks.
