Among the most innovative and promising technologies at present time appears without place to doubts Li-Fi (Light-Fidelity), a technology based on high-speed data transmission using visible or infrared light, a complement to Wi-Fi based solutions for broadband access in diverse indoor or ad-hoc environments. The estimation of wireless optical channel parameters in such environments is of great importance for the prediction and optimization of such systems. Traditionally efforts have been made in this direction: the simplified analysis of empty scenarios, that is, devoid of furniture or obstacles of any kind typically present in offices and working environments where Li-Fi access systems would be deployed. The present work proposes the application of a general model of simulation of the propagation of optical signals in the wireless channel, developed previously by the authors and based on Monte Carlo ray-tracing and the use of bidirectional reflectance functions (TRM-B model), applied to enriched virtual environments, that is to say, digitally synthesized 3D environments that recreate with more precision the characteristics of real deployment scenarios, which allows a more accurate estimation of the channel parameters and its performance for Li-Fi systems.

Palabras clave : Li-Fi; VLC; optical wireless channel; Monte Carlo ray-tracing.
