N2 - An indoor visible light positioning system using the received signal strength intensity method and the trilateration technique with user mobility support is proposed for applications, e.g. healthcare. Accurate position information of medical staffs and patients is required for data transmission, tracking, navigation, etc. Seamless data transmission while user is on the move has been conceptualized considering the optical network formed by photosensor (light emitting diode)-based transmitters. Efficiency of these services depends on the position accuracy. To investigate factors contributing to higher position errors in a practical environment, the proposed system is evaluated. Evaluation is done through simulation and experiment for different channel conditions, and the receiver rotation due to user mobility. Simulation results show an average two-dimensional position error of 0.32 m in a channel with a strong background light illumination level of − 60 dBm. Experimental results show that the mean position error is 0.7 m in a normal daytime indoor light condition.
