Data transmission with LEDs

Web resource:
Researchers at the Fraunhofer Heinrich Hertz Institute in Berlin and at Siemens AG have successfully achieved a data transmission rate of 500 megabits per second (Mbit/s) using a commercially available LED.


This article provides information on the advantages of data transmission with light compared to wireless transmission and shows possible applications.

Information and ideas:
This technology is also applied in the construction of LED miniprojectors that can be integrated into digital cameras or mobile phones. This technology would make it possible, for example, not only to take photos but also to immediately project them on a wall. A small blue laser diode is used for this.
