Background/Objectives: This paper investigates the Line of Sight(LOS) Optical Wireless Channel(OWC) characterization for Visible Light Communications (VLC) designing a realistic indoor environment adding path loss along with Additive White Gaussian Noise (AWGN) to the channel. Findings:The results are very promising, as the transmission distance has been significantly increased maintaining the optimal quality of transmission. The quality of transmission is evaluated by measuring the quality of images received under various channel impairments. The effect of various channel impairments on data transmission has been discussed and elaborated generating various simulation scenarios. Applications/ Improvements:The propose indoor OWC for VLC enhances the transmission range from 4 meters to 6 meters having optimal quality of transmission in a channel representing real indoor environment.
