China achieves wireless Internet access via lightbulbs
IT Professor Chi Nan of Fudan University states that four computers under a one-watt LED lightbulb can connect to the Internet under the principle that light can be used as a carrier instead of traditional radio frequencies. Lightbulbs with embedded microchips can produce data rates as fast as 150 Mbps, much higher than the average broadband connection.
With the technology still in the early stages, research is being conducted to solve problems such as blocked light, which cuts off the signal. Light communication controls, microchip design, and manufacturing are also keys to making wireless internet access via lightbulbs successful.
