  title={Indoor Navigation System Based on LiFi Technology},
  author={S. Divya and Karuppannan Kokila and M. Varshini and P. B. Vishnu Priya and S. R. Zainab Beevi},
In this study we propose an indoor navigation system that utilizes visible light communication technology which employs LED lights aimed at supporting people who travel indoors. The main component of this communication system is high brightness LED, which acts as a communication source and a photo diode which shows good response to visible length region serving as a receiving element. Important factors we should consider while designing Li-Fi are presence of light and line of sight. LED can be… Expand
