This paper presents a Three Dimensions (3D) model of optical power distribution in a diffused cellular indoor Visible Light Communication (VLC) system. To achieve an ideal system which has a maximum coverage area with a minimum power consumption, both hexagon geometric structure and holographic Light Shaping Diffuser (LSD) are employed. The authors analyzed the mathematical models for both square and hexagonal structures with and without using LSD. In addition, the practical system consisting of a (Luxeon Star/O) royal blue LED as a transmitter is used to verify and evaluate the system performance.
