China achieves wireless Internet access via lightbulbs

Summary: Using technology dubbed Li-Fi, scientists have pulled off getting online four computers under a one-watt LED lightbulb, which could eventually be a more cost-effective alternative to Wi-Fi in the country.
Chinese scientists have made headway with successful experiments using Li-Fi technology, where wireless signals are sent by lightbulbs, according to Xinhua News.

Four computers under a one-watt LED lightbulb may connect to the Internet under the principle that light can be used as a carrier instead of traditional radio frequencies, said Chi Nan, an IT professor at Shanghai's Fudan University.
