——Report by Prof. Harald Haas at SSLCHINA 2014
SSLCHINA 2014 will be held on November 6, 2014 at Westin Hotel in Guangzhou.
As one of the largest and most influential international professional forums in China or even the world, SSLCHINA 2014 will gather together the top technical experts as usual. Besides the familiar heavyweights such as George Craford, SSLCHINA 2014 will also invite many new faces at the frontier of technology development. One of them is Professor Harald Haas, who will give a keynote speech at the opening ceremony.
The main research field of Professor Harald Haas is visible light communication. He is a German physicist and Chair of Mobile Communications at School of Engineering of University of Edinburgh, and he has coined the technical term Li-Fi. Previously, he worked as Project Manager at Nokia Siemens Networks. He is honored as one of the leading researchers in the field of LED in the world.
Prof. Harald Haas will attend SSLCHINA 2014 and share his latest research achievements in the field of "visible light communication" at the opening ceremony.
Li-Fi is a brand new wireless transmission technology which uses visible light spectrum for data transmission. The new technology transmits data by changing the flicker frequency of lighting in the room. When the lights are turned on in a room, people can be connected to the internet without WiFi.
Prof. Harald Haas, who is one of the creators of the new technology, is now working with the students of University of Edinburgh to make a change on the traditional media of data transmission through "visible light communication". They try to change the future wireless transmission by using fast flickering LED to realize wireless data transmission of binary numbers.
"Currently, our target is to realize dual transmission function. A bulb is not only an output unit, it can also be a wireless transceiver device, which can be a future communication device as the Wireless Hotspot. We are now reforming the wireless communication technology, which might be a propelling force for the rising of the Internet of Things. We believe it can be the transmission method of the internet in the future," said Prof. Haas.
According to the latest announcements of the University of Edinburgh, researchers are able to transmit data at a speed of 1.1 Gbps within the range of 10 meters through Li-Fi network by using light emitted by micron-level LED. The electric power required is less than 0.5 W and the total power consumption is only 5% of a 10 W LED light bulb.
Since light is not able to pass through walls, Li-Fi is probably safer than the traditional wireless connection method Wi-Fi. Besides, LED bulbs are very popular now, so Li-Fi is expected to be cheaper and more energy-efficient than the current wireless communication system.
