Hybrid VLC communication system for small to medium size enterprises

Abstract

The present paper focuses on the support of the key factors in the components development. This is approached with the design and implementation of a VLC/IR-RF hybrid system (Visible Light Communication / Infrared - Radio-Frequency) based on an innovative and multifunctional thermal sensor measurement module with increased sensitivity, low cost and low energy consumption. This system will have the capability of multi-functional detection for energy consumption monitoring and environmental control in homes, buildings and offices by using an ultra-low-resolution sensor ( $80\mathrm{x}80$ ) called micro-bolometer, which possess the ability to detect movements and ambient temperature. Additionally, the hybrid VLC system will provide the capability of integration of secondary sensors for detecting chemical and physical information from personal buildings and offices. The final goal of the Hybrid VLC/IR-RF project is to provide a hybrid bidirectional optical communication system capable of delivering high performance in terms of maximum communication distance, transfer speed and resistance to sunlight disturbance. The research activities were started by developing a laboratory testbed oriented in this case only on analyzing the characteristics of a VLC communication channel under the influence of the already existing LED lighting sources within the research laboratory.
