Visible Light Communication for Outdoor Positioning: A Review

The scope of visible light communication (VLC) in the navigation industry is expanding day by day. This is due to the potential of achieving high navigation accuracy in indoor and outdoor environments. It outperforms the global positioning system (GPS) in providing precise results. In particular, a GPS may not satisfy the stringent need for centimeter-level accuracy. This paper provides a brief review of VLC technology for outdoor navigation. It explores the solid-state lighting technologies that play a pivotal role in achieving accurate localization. It also identifies some emerging areas of applications for VLC-based outdoor positioning systems.
