Strategy to Improve the Positioning Accuracy of Bluetooth in a Complex Indoor Environment

Bluetooth positioning technology is vulnerable to multipath interference, signal occlusion and other factors in a complex environment, which cannot meet the requirements of high precision positioning. In order to improve the positioning accuracy of Bluetooth, this paper summarizes several technical principles of Bluetooth positioning, focusing on three key influencing factors: environment, hardware and algorithm. Then, through integrating the research results of recent years, this paper puts forward precision improvement strategies from three perspectives: hardware optimization, algorithm improvement and system design. The effectiveness of the technology is validated through real-world applications in commercial, industrial, and medical sectors. Finally, addressing technical bottlenecks in complex environments, this study explores future development directions such as multi-technology integration and intelligent algorithm iteration, providing theoretical and practical references for high-precision Bluetooth positioning applications in smart scenarios.
