Recently, at the 7th China Industry-University-Research Cooperation Innovation Conference in Chongqing, Academician Yan Jiangxing, Director of the National Digital Exchange System Engineering Technology Research Center, revealed that China is currently on the same starting line as developed countries in basic research and practical application of visible light communication. TV, mine communication and other aspects have been successfully applied, but it is expected to take more than five years to be used in the family.
The so-called visible light communication uses visible light to realize wireless communication, and mainly transmits information by means of high-speed bright and dark flickering signals that are invisible to the naked eye, such as LEDs.
"You don't need to spend a lot of money to build communication base stations everywhere. With the ubiquitous light resources, people can have a 'wireless router', 'communication base station', 'WiFi access point' by adding a chip to the LED bulb. Even the 'GPS positioning' feature. Academician Yan Jiangxing, Director of the National Digital Switching System Engineering Technology Research Center, introduced.
Qi Jiangxing said that compared with traditional wireless networks, visible light communication has the advantages of faster transmission speed, wider coverage, energy saving economy, green health, and reliable compatibility.
"Visible light communication will be a strategic emerging industry with trillions of output value." In the view of Hui Xiaobing, executive director of the China Industry-University-Research and Investment Financing Alliance, the future visible light communication will not only upgrade the traditional lighting and communication industries, but also It has spawned a large number of emerging industries, especially promising applications such as optical navigation positioning, secure communication and payment, and intelligent traffic control.
It is reported that China has already incorporated the first visible light communication project into the 863 program.
