Abstract: The Radio Frequency (RF) suffers from interference with most electronic devices, limited, scar, expensive and also it can penetrate through walls that make it unsecure. To overcome these limitations, we used Visible Light Communication Technique (VLC) that use Light Emitting Diode (LED) for transferring data, in addition to its main function, lighting .VLC system uses LEDs due to its higher data rate, longer life time, easy to install and low cost, so it is preferred rather than other lighting sources. VLC transfers data over a range in Electromagnetic (EM) spectrum which is visible to human that’s from (380-750nm). In this paper, we report a simulation program for indoor visible light communication environment based on Matlab where we introduce both Line of Sight (LoS) and Non – Line of Sight (N-LoS) models for visible light source and photodiode in wireless communication and introduce for the first time the effect of reflections from the room four walls on the receiver surface.
