|Issue Date:||2016||Conference:||22nd European Wireless Conference, EW 2016||Abstract:||So far, most of the research activity on visible light communications (VLC) technology has been focused on the communication problem, paying very little attention to the layout design and implementation conditions of practical illumination systems. Therefore, in this paper, we propose to evaluate and analyze the VLC channel effects imposed by a realistic indoor LED-based lighting system. A modified Monte Carlo-based ray tracing algorithm is employed to evaluate the VLC channel impulse response for a typical office room as a function of the wavelength, the physical characteristics of the light sources and their layout in the room. A commercial lighting design software is employed to adopt a realistic lighting layout. Results show that the VLC system's bandwidth is clearly influenced by the spatial distribution of the light sources, but more important, there are some time-synchronization challenges among the emitters that should be addressed before attempting to integrate the VLC technology to the indoor lighting market.||URI:||http://hdl.handle.net/10553/46228||ISBN:||9783800742219||Source:||European Wireless Conference 2016, EW 2016, p. 395-399|
