Many outstanding scientific innovations are taking place in the world and Li Fi currently is a hit in that list. This amazing innovation has been developed by the Chinese who have been successfully able to develop a new and a much cheaper way to get connected to the world of internet by the use of signals which are sent through light bulbs, making the use of radio frequencies obsolete which is used in the current ‘WiFi’ connection. This huge step has been quite appreciated by many and may change the entire process of connectivity to the internet.
Chi Nan who is an information technology professor currently teaching in Shanghai’s Fudan University told the press that a single one watt LED bulb can be used to connect four computers to the internet using light as the carrier of the signals instead of the conventional radio frequencies used in WiFi.
It was told by him that a light bulb making use of embedded microchips is able to produce data rates which can be as fast as the speed of 150 megabits in a second. This speed is judged to be quite speedier than the average speed of the broadband connection in China. The researcher Chi Nan currently leads a Li-Fi research team which has included scientists from the Shanghai Institute of Technical Physics.
The name Li-Fi of this technology was originally coined by Harald Haas, who is a researcher working in the University of Edinburgh located in the UK. The name refers to the visible light communication technology delivering a networked, high-speed, mobile communication which is working in a similar manner to Wi-Fi.
The new technology Li-Fi has been made cost effective and quite efficient as well. 10 sample Li-Fi kits will be made available on display in the China International Industry Fair which will take place on November 5 in the great city of Shanghai.
The main contributor to this project, Chi Nan also told the reporters that this technology has made use of the fact that millions of base stations which are established all over the world strengthen the Wi-Fi signal but a greater part of the energy is spent on their cooling, rendering only 5 per cent of utilization rate, which this technology shall avoid.
It will be a tough fight for Li-Fi to compete with Wi-Fi technology but still people would be wondering as to how effective this Li-Fi technology would be after it will be made available to the common public.
