Recently, China's "key technology research on visible light communication systems" has made a major breakthrough, and the real-time communication rate has been increased to 50Gbps (bits per second), which is equivalent to 0.
2 seconds to complete the download
of a high-definition movie.
Visible light communication is a new high-speed data transmission technology
that uses the light of semiconductor lighting (LED lamps) to realize "Internet access when there is light".
Visible light communication technology is green and low-carbon, can achieve near-zero energy-consuming communication, and can effectively avoid weaknesses such as radio communication electromagnetic signal leakage, and quickly build a safe information space
that is anti-interference and anti-interception.
It is reported that at present, the world has a lighting network composed of about 44 billion lamps, and tens of billions of LED lighting equipment and other equipment will be integrated to build a huge visible light communication network
.
In the future, after the realization of large-scale visible light communication, each lamp can be used as a high-speed network hotspot, people can download several movies under the street lamp when waiting for the car, and wireless high-speed Internet access with the help of LED light sources on airplanes and high-speed trains can meet the needs of indoor networks, Internet of Things, Internet of Vehicles, and Industry 4

The wireless communication requirements of network terminals such as secure payment, smart city, national defense communications, weapons and equipment, and electromagnetic sensitive areas provide a new and cheap access method
for Internet +.
In the next few decades, the amount of information transmission will exceed the carrying capacity of the existing radio spectrum, visible optical communication technology can effectively break through the dilemma of serious shortage of radio spectrum resources, is one of the next generation wireless communication technologies with broad application prospects, and can form a strategic emerging industry
with an annual output value of trillions.
