Li-Fi is coming soonLIFI (Light Fidelity), known as visible light wireless communication, also known as optical fidelity technologies , is a data transmission technology using a light bulb. light. Li-Fi technology using LED lights everywhere, thanks to a tiny chip implanted on the bulb formation, is similar to AP (Wi-Fi hotspot) devices; terminals can access the network at any time. LIFI invention designed to challenge existing Wi-Fi technology, but given the limitations of this technique,Recently, the School of Information Sciences and College of Engineering positive news, a light transmission network signal visible inside the cutting-edge international communications LIFI has managed to achieve in the laboratory. Researchers report the network to 1W LED lamp bead, light and 4 computers Internet, offline speed up to 3.25G, real-time system average Internet access rates of up to 150 M, one of the fastest “light Internet” in the world. Next month, 10 prototypes will be unveiled at the 2013 Shanghai Industrial Fair. Herald HassLi-Fi, English abbreviation of "Light Fidelity", called in Chinese "wireless visible light communication", by Herald Haas and his team at the University of Edinburgh in 2011., a patented technology, this technique uses rapid pulses radio transmission of information, and their use is currently (October 2013) in its infancy. LIFI principle Li-Fi lamp to transmit data via microchip to ordinary device Retrofit LED bulbs, the bulb flashes very quickly, you can send data using bulbs. Light bulbs flash millions of times per second. In this way, the LED bulb can quickly transfer binary coding. However, for an open hole, these flashes are not visible, only the sensitive receiver can detect them. It's so...... middle of paper ......the first product since its creation, equipment worth 5,000 euros. PureVLC will also make, thanks to a system already installed at the Baxley Business Academy in London, with light as a support, a live speech by the Mayor of London, Boris Johnson (Boris Johnson). Li-Fi crushes Wi-Fi and dominates the landscape of the future, and has even had a huge impact on telecom operators, and the force of impact would be unprecedented.ChinaOctober 15, 2013, College of Laboratory Technology of Computer Science from Fudan University successfully implemented the visible light transmission network signaling technology. Researchers report the network to 1W LED lamp bead, light and 4 computers Internet, maximum throughput of 3.25G, average Internet access rates of up to 150M, one of the " "Lightweight Internets" the world's fastest. In November, 10 prototypes will be unveiled in 2013 at the Shanghai industrial fair.
