SINR analysis and cell zooming with constant illumination for indoor VLC networks

Abstract

Visible Light Communication offers potential for dual purpose devices providing both wireless data and illumination; however much of the early research in the area has focused primarily on link capacity. In this work, an RF cell zooming method is adapted for VLC such that the additional requirement of constant illumination is met. This method has the potential to improve traffic distribution in multi-user environments and handover at cell edges when considering mobile users. SINR is observed and analyzed in a range of scenarios to show coverage variability when transmitters are capable of dynamically changing their signal power.
