In China there was a wireless Internet transmits data via normal bulbs Bashny.Net

Chinese scientists have achieved significant results, having successfully tested Li-Fi technology, where wireless signals transmitted through ordinary led lamp.
In this situation, four computers can connect to the Internet using one-watt led bulb using light as a carrier signal instead of the ordinary radio waves, according to Professor of information technology from the Shanghai Fudan University Chi Nan.





Light bulb with built-in chip can provide a transfer speed of 150 megabytes per second is a lot more than the average broadband connection in China.



Currently the wireless equipment is quite expensive and ineffective, commented Chi. "For example, in the case of mobile phones worldwide was built millions of base stations to strengthen the signal but most of the power of their network goes to the cooling system, she says and adds that the coefficient of utilization of their energy amounted to only 5 percent.



We remind you that recently created a special device that will speed up and stabilize Your Internet connection.
