Professor Chen Hongda and Chen Xiongbin, researchers from the State Key Laboratory of Integrated Optoelectronics, Institute of Semiconductors, Chinese Academy of Sciences, have been engaged in research on visible light communication technology since 2008. He has presided over the important direction project of the Knowledge Innovation Project of the Chinese Academy of Sciences under the Visible Light Communication and the National Science and Technology Support Program Expo. Participated in the project. The "973" and "863" scientific research tasks in the field of visible light communication research. The Beijing Municipal Science and Technology Project topic “Development of Transceivers and Handover Devices for Indoor High-Speed ​​Visible Optical Communication Systems†conducted by Chen Xiongbin (Period from January 2014 to December 2015) has been completed as planned. The research team commissioned the China Tell Laboratory of the Ministry of Industry and Information Technology to conduct a third-party test on the single-channel real-time 610Mbps visible light communication. The results are as follows: Based on 1 watt fluorescent white LED and PIN detector under OOK modulation single-channel real-time transmission of the average rate of 610Mbps, in the transmission distance of 6.2 meters, the average BER of 3.5e-5 magnitude, far lower than the forward error correction The upper bit error rate requires 3.8e-3. Based on the research foundation of high-speed real-time transmission of visible light communication technology, the research team built the following types of visible light communication demonstration systems: 1. Two-way symmetrical 100Mbps light access system based on 1W fluorescent white LED and PIN detector. 2. Two-way symmetrical 10Mbps densely populated lighting internet access system based on 1 watt blue LED and PIN detector. 3. Mobile phone visible light communication system and multimedia broadcasting system based on fluorescent white LED and PIN detector. Chen Xiongbin believes that the new technology of visible light communication, wireless optical communication, is more in line with the development direction of wireless communication technology than traditional radio communication technology (high speed, large capacity, and security), and will lead to many innovative applications in the future. China has a large number of LED companies and a vast semiconductor lighting market. This basic advantage is beyond the reach of other countries. The practical research of visible light communication technology should arouse everyone's attention.
Wastewater treatment is a process used to convert wastewater-which is water no longer needed or suitable for its most recent use-into an effluent that can be either returned to the water cycle with minimal environmental issues or reused. It takes an important part in improve our environment.
