Potentialities and challenges of VLC based outdoor positioning

摘要

While visible light communication (VLC) with inherent advantages is believed to be the next generation of wireless technology, positioning using visible light also has the potential of becoming a standard approach for positioning in the future. Although many indoor positioning systems based VLC have been proposed recently, there is very few paper related outdoor positioning using visible light. In this paper, firstly we point out difficulties when using visible light for outdoor positioning. Then we survey existing indoor positioning techniques using visible light and evaluate the potentialities and challenges of applying them to outdoor positioning.
