Chinese professor builds Li-Fi system with retail parts

Michael Kan | Nov. 6, 2013
The equipment is big and expensive, with the research costs at almost US$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.

Over time, however, the Li-Fi receiver could conceivably take the form of a USB dongle that attaches to a notebook. Chi estimates it will take another five years before the technology can enter the market as consumer products. So far, her team has spent about 18 months on the project.
