Personal optical wireless communication POW is a promising solution for increasing the available communication bandwidth within a room. This technology can offer, with line of sight and diffuse propagation, very high-speed communications between portable devices. This paper presents a generic line of sight, wide line of sight (LOS/WLOS) propagation model and a diffuse (DIF) propagation model for the design of wireless optical communications. It also presents a software tool, with these models, offering the possibility to simulate the optic path loss models in a room. This simulation can be shown with furniture and optical wireless equipments in 2D or 3D view.

Optical wireless communication link (OWCL) requires a good transmission channel characterization. We present a physical method that uses a reduced-size model in order to characterize the impulse response of the optical wireless channel in real indoor environments filled with furniture. High resolution and real time characterization are the advantages of the method.
