Experimental study on optical power distribution of indoor visible light communication

Abstract

Abstract: Indoor visible light communication technology is based on white LED(Light- Emitting Diode) light source of optical wireless communication technology. At the airport, hospitals and other places where there are strict limits of electromagnetic interference, the technology can replace the radio communications, which has profound application prospects. Considering the influence the wall reflections during the indoor visible light transmission has,The indoor visible light illumination distribution was acquired by experimental measurements in a room of 4.0m×4.0m×2.8m. The conclusion shows that the light source of the optical signal reflected by the wall will produce severe multipath effects,and then limits the communication rate. In this thesis, The experimental verification of indoor visible light distribution and simulation research was carried out. Moreover, the results of the experiment nearly agree with the theoretical simulation research.

Key words: Visible light communication, Multipath effects, Illumination distribution
