Researchers from the Fraunhofer institute are there to say managed to get through to the led lighting data wirelessly with a speed of up to 3Gbps, to send. Previous attempts with the technology remained stuck at 230Mbps.

The German Fraunhofer institute is investigating for some years the possibilities to use led lamps to use for data transmission via so-called visible-frequency wireless – or visible light communication technology. This can be very rapidly oscillating leds are used to using visible light data to send. Thanks to this undetectable rapid flashes at terahertz frequencies with multiple led lamps and lichtdetectoren ‘lifi networks,” to be built.

Fraunhofer succeeded in 2010 in to with leds in onderzoeksopstellingen speeds of up to 230Mbps to achieve, but in the meantime, the researchers have the throughput significantly increased. Multiple colors to use, would the German researchers are able to data through lifi equipment up to 3Gbps to send. What do you want out of the research lab in less than ideal conditions as possible, is not made known by the research institute, reports ExtremeTech.

Because lifi networks use unregulated frequency band, can in principle be freely used. In addition, interrupting such networks do not have an existing wi-fi technology, allowing lifi, for example, can be used to busy wi-fi access points, to relieve. It would also be useful in places where wi-fi is undesirable, for example in hospitals. Despite years of research, the first concrete lifi-hardware and applications are still on the market.
