China LiFi technology breakthrough will be an annual output of one trillion industry

CNR network reported by the Ministry of industry and information technology testing and certification, China's "visible light communication system key technology research" has recently achieved a major breakthrough in the real-time communication rate increased to 50Gbps (bits per second), the equivalent of 0.2 seconds to complete a high-definition movie downloads.

Optical communication is the use of semiconductor lighting light, that is, LED lamp light to achieve the light will be able to access the Internet, a new high-speed data transmission technology. This technology is green and low carbon, can achieve near zero energy communication, but also can effectively avoid the leakage of electromagnetic signals such as radio communications vulnerabilities, rapid construction of anti-jamming, anti interception of the security information space.

According to our information field of famous experts, China Academy of engineering, Wu Jiangxing said that the current global lighting network has about 44 billion lamps consisting of tens of billions of LED lighting equipment and other equipment to build a huge fusion of visible light communication network. You can imagine, the future large-scale visible light communication, each lamp can be used as a high-speed network hotspot, that is to say, people waiting for the bus, on the street you can download some movies in the aircraft, high-speed rail can also be used LED light source wireless high-speed Internet access, meet the indoor network, networking, car 4, industrial networking, secure payment, smart city, national defense communications, weapons and equipment, electromagnetic sensitive areas and network terminal wireless communication demand, provide a new cheap access method as "Internet +".

Wu Kong Hing forecast, in the next few decades, the amount of information transmitted will exceed the capacity of the radio spectrum, thus the optical communication technology can effectively break the radio spectrum resources is a serious shortage of predicament, the next generation of wireless communication technology has broad application prospects, can also form a trillion annual output value of strategic emerging industry.

It is understood that this high-speed transmission has been a focus of research in the field of visible light communication, The PLA Information Engineering University, Yu Hongyi research team used processing method of optical and electrical coordination, broke through the visible space channel interference suppression technology, has now entered the design, integration, miniaturization and implementation stage, expect communication application the new life as soon as possible to the people.
