KingSun has with the Tsinghua University successfully developed a visible light communication mobile phone version of the sample

(6) Dongguan KingSun Au Optronics Co micro-blog admit, with Tsinghua University in May 2013 signed a cooperation agreement in the field of visible light communication and positioning. At present, has successfully developed Lifi mobile phone version of the sample, is expected to eventually reach the size of iPhone and the degree of light can be achieved in the market.

You are not allowed to turn on any radio equipment on the plane. If you turn on the cockpit lights on your head, you may be able to get on the internet.

In the evening, the driver's line of sight is blocked, traffic accidents are difficult to avoid, if the car's LED lights can talk to each other, and even traffic lights and exchange of information, perhaps we will be more secure.

No WiFi signal, the point of a LED lamp will be able to access the Internet is not fantasy. The use of indoor visible light transmission network of international cutting-edge communications technology in the laboratory of Fudan University successfully.

German physicist Harald Haas (Haas) and his team at the University of Edinburgh in the United Kingdom first invented the patented technology. To transmit digital information with flashing lights, this process is called visible light communication (VLC), people often call it the "LiFi", to show it to the wireless network transmission technology represented by WiFi may bring revolutionary change.

Both contrast, each has advantages and disadvantages

However, LiFi can completely replace WiFi? Perhaps from the table below, we can see.

By comparison, people may have a lot of problems, such as: daytime lights to the Internet? Visible light cannot penetrate the object, if the light is blocked, the signal will be cut off the mobile Internet is how to do? How to use the mobile phone we represent the general trend, the lights on the Internet?

For these problems, the researchers late Professor Nan said that the international community has been in the study of a new technology, in the case of LED lights do not emit light, through the realization of the current function of the Internet access. "LiFi is not a competitor to WiFi, but a complementary technology that helps to release spectrum space. The inventor Haas is said, we still need WiFi, when the light signal is blocked, you can seamlessly switch to the RF communication system. In addition, for the Fudan University, the task force is now the most need to overcome is how to fill the circuit and a variety of devices to reduce the transmitter receiver narrowing, and finally put into a chip. Haas, the inventor of the technology, suggested that the LED could be sent to a bulb by installing a microchip.

In addition, China industry insight network researcher Lin Lin told reporters, visible light communication technology, not only relates to the communication technology field, the technology category also relates to visible light, so the industry will also have a lot of work to improve the certification and review.

Market prospects and how to intervene?

Research institutions MarketsandMarkets pointed out that the visible light communication technology will be increasingly used for WiFi and mobile phone network data complement, while total sales in the market is expected from 2012's $96 million increase to $6 billion 140 million in 2018 scale.

At present, the visible light communication is dependent on the LED lighting, so the popularity of the LED indoor lighting market has become a prerequisite for high-speed optical communication market. The national key basic research and development plan (973 Plan) project chief scientist Xu Zhengyuan stressed that is different from the outdoor lighting by a large number of government investment, LED interior lighting should be widely accepted by thousands of households, to further improve energy efficiency, reduce the cost. At the same time, with the help of low cost visible light communication module, the integrated LED lighting will arouse the strong interest of consumers and investors, and achieve a win-win situation for lighting enterprises and communications companies.

Dongguan KingSun Au Optronics Co (hereinafter referred to as KingSun) in May 2013 and the Tsinghua University signed a cooperation agreement in the field of visible light communication and positioning. It is understood that KingSun laboratory with Tsinghua University has successfully developed a Lifi version of mobile phone communication samples, is expected to eventually reach iPhone size and thin degree can be achieved market.

KingSun assistant general manager, spokesman for the cast in an enterprise "section to observe" interview with reporters, said: "LiFi and WiFi seem to have a plasma and LCD tv. Technically speaking, plasma TV may also have more advantages, but because of market promotion, enterprise's tendency to guide and consumer acceptance, resulting in plasma did not realize industrialization, to withdraw from the market situation. Therefore, the LiFi from the laboratory to the actual application, but also depends on the development of the whole industry chain, especially the development of LED lighting companies and the popularity of LED lighting. "

KingSun in outdoor lighting and indoor lighting applications, already began to use intelligence and signal transmission. Our next goal is to LiFi as the carrier to achieve more remote data transmission, including wireless transmission. Duan Zhu said.

Lin Lin told reporters, compared with Wifi, Lifi technology is a new technology, but want to make its massive popularity into people's lives, must pass a series of industrial development, formed a complete industrial chain structure. While the current Lifi technology is still in the laboratory stage, want to access the communication network for each bulb, a huge amount of work, there is no enterprise to join the industry. "
