Li-fi Technology China’s new and amazing invention
Chinese scientists have successfully developed a new technology named “Li Fi” the better, fast and cheap alternative of Wi Fi Technology. Chinese scientists claim that they have invented a better, reliable and cost-effective technology than the current technology “Wifi”, Li-Fi
Technology works on a Light Bulb called LED (Light Emitting Diode). Professor Chi Nan of Shanghai institute of technical physics Chinese academy of sciences claims that her team is successful in inventing a technology which works on a 1 Watt LED capable to connect 4 PC’s
simultaneously to the internet. Data travels over light signals instead of radio waves. Chi Nan Says, in Li-Fi Technology, special Micro Chips are used along with the LED’s to get access to the Internet and the speed of this technology can be extend to 150 Mbps which is higher than
the current internet speed in China.
Li-Fi technology stands for “Light-Fidelity Technology” and uses visible light instead of Gigahertz radio frequency. The term “Li-Fi” was coined by Harald Haas from University of Edinburgh in the UK and refers to a visible light technology which will work on a similar principle as
Wi-Fi does. Chi said, the current wireless signal transmission equipments are costly and low in efficiency. Whenever there is light, there is Internet. No light no Internet. Now your Car lamps, street lights and room bulb are your source to fastest Internet.
How Li-Fi technology Works
Li-Fi Technology works in the same manner to Wi-fi. Li-Fi Technology uses light signals to transfer data. LED’s are switched ON and OFF so faster than the human eye can detect and it seems to be continuous. Li-Fi Technology transfers signals in Binary Form (1 and 0), 1 represents
ON State and 0 the Off State. A Micro chip added to the LED controls the ON and OFF Switching. Suppose you have a LED at sending end which flashes and sends signals and a Photo Detector receives signals on the other end. As soon as light flashes the photo detector detect the
signals as 1 or ON otherwise 0 or OFF. Flashing the light many time will build a message and enable the data to travel. This is how Li-Fi Technology.
Pros and Cons of Li-Fi Technology
1. Internet can be accessed in those areas where optical fiber is not easy to deploy. 2. Provides good connectivity where there is light even in streets. 3. If it creates a bridge of network, all the lights of your house will act as a source of internet means full signals and great
connectivity. 4. Faster than the Wi-Fi technology
Cons of Li-Fi Technology
1. This technology works on exact line of sight, means light will not pass through the walls, we will be bound to a room. 2. How data will be transmitted back to the LED. 3. Long distance links will not be easy to create
Future of Wi-Fi Technology
It seems like Li-Fi Technology will beat Wi-Fi Technology in indoors but it will take some time to do so.But Li-Fi Technology does not seems to be beating it in outdoors. However we are looking forward to the Public display of Li-Fi kits which are to be displayed at China’s
International Industry Fair on 5 of November 2013 in Shanghai.
