Abstract

Li-Fi (Light Fidelity) stands as a state-of-the-art wireless technology that sends data through light-based transmissions. Mobile robots require effective indoor location systems because they operate within hospitals, museums, and airport interiors. Researchers have studied the behavior of the On-Off Keying (OOK) modulation technique used in Li-Fi systems by observing the impact of background interference. Our model determines the performance of a 550 nm wavelength white LED transmitter using Opti System software. Evaluation of the system occurs through examinations under two conditions: when ambient light noise exists and when it does not. The research outcomes demonstrate that Li-Fi technology can deliver dependable high-speed indoor localization services for environments experiencing changes in ambient lighting conditions. Simulation findings indicate a Q factor measurement of 6.47 with noise, while the results show 19.18 when noise is not present. The network supports 10 Gbps data transmission at 2.96e-11 Bit Error Rate with ambient noise and 2.3e-82 Bit Error Rate with ambient noise under a 10-meter connection range.
