Recently, China's "research on key technologies of visible light communication systems" has recently made a major breakthrough, and the real-time communication rate has been increased to 50Gbps
.
This means that 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.
Wu Jiangxing, an expert in the field of information in China and academician of the Chinese Academy of Engineering, said 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 build a huge visible light communication network
.
It can be imagined that after the realization of large-scale visible light communication in the future, 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 can also be used by LED light source on airplanes and high-speed trains to meet the wireless communication needs of indoor networks, Internet of Things, Internet of Vehicles, Industry 4.
