Personal optical wireless communications: LOS/WLOS/DIF propagation model and QOFI

Abstract

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.
