An approach for indoor location estimation to the visually challenged using light fidelity (Li-Fi) technology

Indoor navigation is favorable for every person, and is exclusively essential for the visually challenged. The proposed method uses Light-Fidelity (Li-Fi) technology for transmission of the information. Li-Fi is apt for high-density wireless data exposure in restrained regions that are free of hindrances. Li-Fi is a progressing branch of Optical Wireless Communication and can give greater data rate transmission laterally with the proficiency to employ surplus users since it uses a spectrum bandwidth of wider-range.
