Chinese breakthrough in VLC technology may enable to download a HD Hollywood movie in around 0.3 second!

A new Chinese breakthrough in visible light communication (VLC) technology may enable people to download a HD Hollywood movie in around 0.3 second simply using the light of a lamp. A test conducted by the Ministry of Industry and Information Technology confirmed that the real-time traffic rate of a Chinese VLC system had reached 50 gigabytes per second (Gbps). The real-time speed is the highest obtained by China so far. In August 2014, media reported a group of Mexican scientists used similar technology to transmit data with speeds up to 10 Gbps.

VLCIT expert and academic Wu Jiangxing said it will be possible to establish a huge VLC network based on the billions of bulbs and LED lighting facilities already around the globe.The technology is green and consumes far less energy and can secure information better than radio, which has loopholes such as signal disturbance, leaks and interception, according to the ministry.
