Authenticated by the ministry of industry and information technology test, China's "visible light communication system key technology research" has obtained significant breakthrough, real-time communication rate increase to 50 GBPS (bits) per second, equivalent to 0.2 seconds to complete a high-definition movie download.

China a major breakthrough in the discovery of the visible light communication transmission speeds up to 50 g per second

Visible light communication is the use of semiconductor lighting (LED) light to achieve "a light can get to the Internet" a new type of high speed data transmission technology. Visible light communication technology green low carbon, can achieve almost zero communication, energy consumption, also can effectively avoid weaknesses, such as radio electromagnetic signal leak to quickly build anti-jamming, anti hijacking safety information space.

China information domain experts, the Chinese academy of engineering jiang-xing wu said that at present, the world has about 44 billion light lamps and lanterns lighting network, consisting of tens of billions of LED lighting and other equipment integration will construct a giant optical communication network.

Can imagine, after a massive visible light communication in the future to realize each lamp can be as a high-speed network hot spots, people waiting for the bus under the street lamp can download films, on the plane, high iron can also use the LED light source wireless high-speed Internet access, meet the car interior network, Internet, networking, industrial 4.0, secure payment, the wisdom city, national defense communications, weapons and equipment, electromagnetic sensitive areas such as network terminal wireless communication requirements, provide a new cheap Internet + access method.

Jiang-xing wu predicts that in the coming decades, information transmission will be beyond the bearing capacity of existing radio spectrum, visible light communication technology can effectively break through the dilemma of the serious lack of the radio spectrum resources, is one of the next generation wireless communication technology has a broad application prospect, can form a trillion-dollar annual output value of the strategic emerging industries.

High speed transmission has been the focus of the researches on the visible light communication subject. PLA information engineering university hong-yi yu r&d team coordinate by optical and electrical methods, break through the visible space channel effective inhibition of key technologies, such as mutual interference, entered the stage of integration, design and implementation of miniaturization.

This university is China's earlier engaged in visible light communication technology research and development of scientific research units, in 2013 led to undertake the first visible 863 program project in China, and formed a "visible optical communication industry technology alliance in China". After more than three years of scientific research, has developed "visible on demand TV business" "new radio" visible light "visible precise positioning" to demonstrate the application system.
