Fudan Internet network to achieve light speed 150M replace wifi? Looks beautifulREVIEW: no WiFi signal, point a Nike Air Max Lebron 10 Low LED lamp able to access. Yesterday, Fudan University researchers access to a network signal light 1W LED lamp beads, four computers to the Internet under the lights, the highest rate of up to 3.25G, the average access rate up to 150M. Replace wifi? It looks beautiful. If the light is blocked, the network signal will be cut off. You look at a black band was Marco. Find inspiration, digging a dark horse, comment hotspots, here is the dark horse Nike Hyperdunk 2013 news agency: no WiFi signal, point a LED lamp able to access. Yesterday, the Department of Computer Science and Technology, spread the good news, a use of the house visible light transmission network signals the international forefront of communications technology in the laboratory successful. Researchers will Kobe Bryant access a network signal light 1W LED lamp beads, four computers to the Internet Nike KD V Elite Low under the lights, the highest rate of up to 3.25G, the average Internet speeds of up to 150M, called the world's fastest 'Light Internet.' Next month, 10 prototype will be unveiled in 2013 Shanghai International Industry Fair. Visible light communication is called Lifi has Nike Air Max 2012 Men been on a person's head to draw a shining light bulb, it is used to symbolize an inventor's idea came, but the German physicist Harald Haas from the bulb itself. ' lighting 'of whimsy: a tiny light-dependent, the invisible network signal becomes' visible 'network signal. Haas and his team Air Jordan Outlet at the University of Edinburgh's latest invention, a patented technology that uses flashing lights to transmit digital information, this process is called visible light communication Nike Air Jordan 10 (VLC), people often put it affectionately known as 'Lifi', to show it to the currently represented WiFi wireless network transmission technology may revolutionize. This is hard to imagine a network technology in the end far away from us? The answer is: very close, it is she keeps coming to us from Fudan University laboratory. Professor, Department of Computer Science and Technology Xue Xiangyang told reporters, there are many limitations of current radio signal transmission devices that rare, expensive, but the efficiency is not high, such as mobile phones, Air Jordan Women the world's millions of base stations to help them enhance the signal, but most energy is consumed in the cooling efficiency of only 5%. In contrast, Womens Heels the lamp used worldwide but inexhaustible, especially in the domestic large-scale LED light source is to replace the traditional incandescent lamp. Just add Nike Air Max a microchip in any humble Nike Air Jordan 5 Women LED bulbs, you can let the bulb into a wireless network transmitter. Visible light communications security and the economy began last year, the Shanghai Municipal Science and Technology Commission have been universities and research institutes layout of the international forefront of wireless communications technology in the city, visible light communication key technology research and application undertaken by the Fudan University made significant progress: researchers not only in a lab environment using visible signal transmission network, and can achieve 'a drag four', that lit a small lamp, four computers can access the same time, mutual transfer network signals. Professor Chi Nan research staff noted that light and radio waves, all belong to an electromagnetic wave, the basic principles of propagation network signal is consistent. Study, to ordinary LED bulbs mounted on a microchip that can control it millions of times per second flashing light indicating 1, off represents 0. As the frequency is too fast, the human eye can not perceive, but light sensor can receive these changes. In this way, the binary data is encoded into light signals rapidly and effectively transmitted. Computer under the lights through a special receiver, read in the light of 'Morse code.' 'There is light where there is a network signal to turn off the lights, network no.' Chi Nan told reporters, compared with existing WiFi, visible future communications security and the economy. WiFi rely invisible radio wave transmission equipment power is growing, it is bound to enhance local electromagnetic Nike Air Yeezy II radiation; a wireless signal through walls, network information secure. These security risks in the visible light communication 'wiped out.' Moreover, a large spectrum of radio spectrum than 10,000 times, which means more bandwidth and higher speed, network settings and almost no new infrastructure. Lifi technology has its limitations, of course, still in the laboratory as a new network technologies and products, and its future potential should not be overestimated. 'Because, from lighting control to communications chip design and manufacture of a series of key technology products, all the Nike Kobe 9 researchers 'DIY' to really like WiFi as every family, through a series of industrial development, there is still a long way to go. 'Chi Nan believes, Lifi technology itself has its limitations, such as if the light is blocked, the network signal will be cut off, and so on. Therefore, it is not WiFi Cheap Nike Free Outlet competitors, but a complement to each other, to help release the spectrum space. Its future, the ability to produce killer type of application, but also on people unlimited imagination: between cars rely LED lights to 'dialogue', the use of aircraft passenger cabin overhead LED reading Nike KD 7 Kids light to the Internet ......
