LED visible light communication technology Li-Fi has made breakthrough
Li-Fi is the use of visible light for data transmission pop new wireless transmission technology, invented by the German physicist Harald Haas. The technology, by changing the frequency of the light flashes in the room for data transmission, can connect to Internet without WiFi as long as the light is opened inside the room.
According to the announcement issued by the university, the researchers used micron light emitted by the light emitting diode, make Li-Fi networks in 10 Minelli with less than 0.5 watts of power to 1.1Gbps data transfer speed, its power consumption is only 10 watts 5% LED bulbs use electricity.
The study by the University of Edinburgh, Scotland ? Harald Haas (Harald Haas) professor, led jointly with the United States pureLiFi completed. Harald Haas ? LED technology is known as one of the leading global figures.
Visible light communication has become the United States, Japan and European countries contested in international communications research. Many experts believe, Li-Fi represents the future trend of mobile Internet. Li-Fi WiFi cost than many because it uses radio waves instead of visible light transmission signal. Large spectrum of radio spectrum than 10,000 times, you can get higher data density.
A U.S. market research company said total sales visible light communication technology market expected to grow from $ 96 million in 2012 increased significantly to 2018's $ 6.14 billion.
In China, there are companies conducting Li-Fi network technology research. Fudan University last October has successfully used the house visible network to transmit signals. At that time the maximum transmission rate was up to 3.25G, an average access rate of 150M.
