A research project from Siemens reportedly broke the record for wireless data transmission speeds by using white light-emitting diodes (LEDs) rather than radio waves. Siemens researchers reportedly transmitted data at 500 Mbps, beating the previous record of 200 Mbps.
The researchers used Ostar LEDs, which is one of the brightest LEDs available. The lights are modulated at a frequency that enables high-speed data transmission. A photodetector receives the light signals and changes them into electrical pulses.
According to Siemens, the technology could be used in numerous areas, such as enhancing the performance of WiFi networks when it comes to interference. The transportation market might benefit by using LED stoplights to transmit information to automobiles.
