Chinese Professor Builds Li-Fi System With Retail Parts

alphadogg writes "The equipment is big and expensive, with the research costs at almost $500,000. But by just using retail components, Chinese professor Chi Nan has built her own Li-Fi wireless system that can use LED lights to send and receive Internet data. "I bought the lights from Taobao," she said, referring to the Chinese e-commerce site. The professor from Fudan University showed off the technology on Tuesday at the China International Industry Fair in Shanghai. Unlike traditional Wi-Fi routers that use radio signals, Chi's system relies on light to send and receive data wirelessly. Others scientists, especially in the U.K., have also been researching the technology, and dubbed it "Li-Fi". But rather than develop specialized hardware, Chi bought off-the-shelf retail parts to create her system."

You pull the racist card so much that eventually will loose any meaning at all. The same for homophobic, socialist, fascist et all.

mod parent up

Even though it was an AC, the parent here was actually funny and should have been modded up. I'm amazed that the modder had nothing better to do with his mod points than mod this down in a mistaken display of Poritical collectness.

What everyone seems to be missing here is this fantastic accomplishment. What the starving Chinese should take grate pride in is there is no little trinket that Chi Nan can fail to duplicate, as long as she doesn't have to pay for it herself.
