Abstract:
This paper investigates the applicability of an intuitive advertising system for large indoor environments using Visible Light Communication (VLC). This VLC based positioning system includes the use of the visible light signal to light the space and to transmit the information for positioning of travelers and of advertising campaigns in the surroundings. An LED-assisted positioning and navigation VLC system is proposed. A VLC scenario for large environments is analyzed, the emitters and receivers are characterized and the communication protocol presented. Different layouts are investigated. Square and hexagonal meshes are tested and a 2D localization design, demonstrated by a prototype implementation, is presented. The key differences between both topologies are discussed. For both, the transmitted information, indoor position, path direction, as well as bidirectional communication are determined. The results showed that the LED-aided VLC navigation system makes possible to determine the position of a mobile target inside the network, to infer the travel direction as a function of time and to interact with the information received.
