Light will be able to access the Internet fax technology refers to the life-saving technology LED

At the end of September 2012, the European institutions innovation and lead the 13 strong potential for the development of start-up technology industry, to the United States, Boston and other places to make a tour of the Silicon Valley, the pure visible light communication (PureVLC) invention (Light FidELity, Li-Fi exclusive light fax) technology, not only has been hailed as the next generation of Wi-Fi network. Show LED industry Savior posture.

Li-Fi is the brainchild of University of Edinburgh's Haas (Harald Haas), as the "time" magazine (Time) said, he is good at will enrich the number of objects of innovative applications, in the case of Li-Fi, the foundation is the world's 14 billion lights, the use of LED chip to control the light source, the million per switch light frequency data transmission.

The surge in global mobile data traffic, radio frequency band is running out of the occasion based on Li-Fi, or can solve the global telecoms as pressing danger. American cable television network (CNN) to estimate the global 14 billion lights if all replaced LED lighting, not only to promote the LED industry is of great significance, will be transformed into street lights can provide hot wireless network, base station and removal of high power consumption space, also have a great contribution to environmental protection.

Intel is also actively R & D

Haas is not the only visible light communication and pure spectral wave spectrum instead of pioneer is committed to research and development, according to the science and technology magazine "online" (Wired) reported that in recent years, Japan and US manufacturers have claimed that developed submarine communication equipment has been mass production of products, such as CASIO (Casio), Intel (Intel), Samsung (Samsung), Boeing (Boing) and other international manufacturers have launched a research program more widely used.

Intel hypothesis, this technology can be applied to the intelligent transportation system, for example: the Li-Fi device is equipped with in vehicle and traffic signals, in order to improve the traffic safety; in addition, there are many specialized in optical technology in Germany, Norway and Israel and the United States company, jointly established international platform Li-Fi group (Li-Fi Consortium), accelerate the pace of development.

Scholars criticize unrealistic

This car is eager for a fight, that car but there are many scholars criticized: "light can surf the Internet communication" is a unrealistic dream, because when the light is obstructed by the object, or mobile phone, the computer itself is not equipped with LED light transmission function, can do nothing.

In response to these criticisms, Haas CNN interview replied: "the development of Li-Fi was not designed to replace Wi-Fi, but complementary, share transfer; as for the light cannot penetrate when communication is interrupted shortcomings, but sometimes can protect the security of signal transmission.
