Visible light communication technology uses high-speed light and dark flashing signals emitted by fluorescent lamps or LEDs that are invisible to the naked eye to transmit information. Connect the high-speed Internet wire device to the lighting device and plug in the power plug to use. The system made using this technology can cover the range of indoor lighting, and the computer does not need to be connected by wires, so it has broad development prospects.
At present, visible light communication has become a battleground in the field of international communication research in countries such as the United States, Japan, and Europe. After my country's 863 Program deployed visible light communication technology research in 2011, after more than two years of scientific and technological research, a number of important research results have been achieved in terms of modulation bandwidth expansion, real-time transmission rate, and converged network architecture.
LED lighting wireless communication is still in the exploratory and initial stages at home and abroad, but it has shown attractive application prospects. It can not only be used for indoor wireless access, but also provide a new method for mobile navigation and positioning of urban vehicles. Car lighting basically uses LED lights, which can form communication links between cars and traffic control centers, traffic lights to cars, and cars to cars. In the future, through visible light communication technology, it will also be possible to surf the Internet and make phone calls on airplanes.
As a pioneer in scientific development, Guangdong has gathered more than half of the country's leading companies in the communications and lighting industries, and has a good LED hardware industry foundation. The exchange between the Provincial Department of Science and Technology and Academician Wu Jiangxing and his delegation will further promote Guangdong to seize the commanding heights of visible light communication industry development and effectively drive the transformation and upgrading of the entire LED industry. It can be said that the current introduction, cultivation and development of visible light communications will be conducive to strengthening the traditional leading advantages of Guangdong's LED industry, cultivating new growth points for the development of Guangdong's LED industry, and realizing the in-depth integrated development of the LED industry and related industries, which has great strategic development significance.
