LED Lights as High-Speed WLAN Transmitters
From Wifi to Lifi: LED Lights as High-Speed Internet Transmitters
Recently, the media has been reporting some very promising news for our communication society. A great new milestone has reached the world of LED lighting as research by the Fraunhofer Heinrich Hertz Institute turns LED light bulbs into broadband data transmitters. The German organization has conducted research in which the light flicker rate of LED light bulbs are manipulated in order to transmit data at the fast pace of 1 Gbps per single frequency. This means that LED light bulbs, which operate at three frequencies, have a bandwidth potential of 3Gbps. By simply placing your PC or internet-enabled smartphone or computer under a radiant LED light you could be streaming data at a high speed. To put the term high speed into perspective, take note that Google Fiber is expected to operate at only 1Gbps, making LED-run data streaming three times as fast. Although this method is not applicable for sending data, it has great potential and usage for streaming data, such as videos, from the internet as long as the device remains placed under the LED light.
