Experimental System Design for Optical Wireless Localization Using RSS Measurements

This work presents the design, implementation, and preliminary evaluation of a LiFi-based optical wireless localization system. The study begins with a comprehensive analysis of LiFi capabilities in a controlled laboratory environment, followed by the initiation of system design and experimental setup.

The localization approach leverages Received Signal Strength (RSS) measurements in the uplink, where signals transmitted from user terminals are collected by multiple spatially distributed antennas. This architecture enhances spatial diversity and improves localization accuracy. Optimal antenna placement and architectural design are emphasized to maximize coverage while minimizing localization errors.

The system design consists of three key components:

1. Transmitter/Receiver Design – Development of circuits ensuring reliable signal transmission and reception between terminals and system infrastructure.

2. Preliminary Results – Experimental RSS measurements at varying distances provide insights into signal attenuation, validate system design, and inform adjustments in antenna placement and processing methods.

3. Processing Platform – A real-time platform for signal acquisition, synchronization, and processing. It enables dynamic RSS analysis, application of localization algorithms, filtering, and performance evaluation.

This structured approach lays the foundation for further refinement of LiFi-based localization systems, demonstrating the feasibility of RSS-driven optical wireless positioning in experimental conditions.
