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. Li-Fi technology using LED lights everywhere, via a tiny chip implanted on the bulb formation, is similar to AP (Wi-Fi hotspot) devices; terminals can access the network at any time. The LIFI invention was designed to challenge existing Wi-Fi technology, but given the limitations of this technique, recently, the School of Information Sciences and the University of Engineering reported positive news, a broadcast network signal of visible light within the cutting-edge international communications LIFI has successfully achieved in the laboratory. Researchers report the network to a 1W LED lamp, light and 4 Internet computers, offline speeds up to 3.25G, real-time system average Internet access speeds up to 150M, one of the "light Internet" fastest in the world. Next month, 10 prototypes will be unveiled at the 2013 Shanghai Industrial Fair. Herald HassLi-Fi, short for "Light Fidelity", called "visible light wireless communication" in Chinese, by Herald Haas and his team at the University of Edinburgh in 2011, a patented technology, this technique uses rapid pulses of radio transmission of information and their use is currently (October 2013) still in the early stages. LIFI principleLi-Filuce lamp to transmit data through a microchip to a normal LED retrofit bulbs, the bulb flashes very fast, you can send data using the bulbs. Light bulbs flash millions of times per second. This way the LED bulb can quickly transfer a binary coding. With the hole open, however, such flashes are not visible, only the sensitive receiver can detect them. This is yes......means of paper......the first product since its birth, a device worth 5,000 euros. PureVLC, through a system already installed at the Baxley Business Academy in London, will give a live speech using light as a medium, London Mayor Boris Johnson (Boris Johnson). Li-Fi overrides Wi-Fi by dominating the landscape of the future and has also had a huge impact on telecom operators and the force of impact would be unprecedented. China On October 15, 2013, the College of Technology in Fudan University Computer Laboratory successfully implemented the visible light transmission network signaling technology. Researchers report the network to a 1W LED lamp, light and 4 Internet computers, maximum speed of 3.25G, average Internet access speed up to 150M, one of the fastest "light Internet" in the world. In November, 10 prototypes will be unveiled at the Shanghai Industrial Fair 2013.
