Abstract :
The paper presents development of a 10 Mbit/s visible light communications link that uses lighting LEDs as both transmitters and receivers. The system uses the simple binary on-off keying modulation without any equalization. Transmission distances exceeding 20 cm were obtained with a low power LED and no light concentrators (lenses). Both the throughput and transmission range are expected to much improve when using high power LEDs and more effective modulation formats.
