In this contribution, we discuss the impact of propagation impairments in indoor and outdoor optical wireless communication. In outdoor terrestrial systems, fog attenuation is the major effect which limit the link length whereas in indoor systems, multipath bounds the available bandwidth and both above parameters quantified through measurements and simulations.
This work reports a set of preliminary predictions of the Signal-to-Noise-plus-Interference Ratio (SNIR) of a Visible Light Communication (VLC) system inside an airplane cabin devoted to provide high-speed Internet access to air travelers. Different conditions of signal sources, noise and interference have been addressed, making use of an in-house developed Modified Monte Carlo (MMCA) ray tracer simulator...
This work reports the development of a MATLAB® simulation tool for the indoor VLC channel characterization. In addition to the evaluation of the light level and the impulse responses in any point of the simulation volume, the modeling of the various sources of disturbance (sunlight, skylight, general illumination devices and interfering ones) is also specifically addressed. The accuracy of the predictions...
