Feasibility Analysis of Self-Oriented BLE Anchors Powered by NEMA Motors for DoA-based Indoor Positioning

Abstract:
Indoor positioning systems (IPS) are widely used in various scenarios, utilizing fingerprinting, Bluetooth, or Wi-Fi technologies. However, the current infrastructure for indoor positioning is insufficient and lacks consistency over time due to environmental changes and other factors. This lack of adaptability to dynamic environments poses a significant challenge in indoor localization today. A fresh perspective is required to address these issues, emphasizing the need for dynamic and adaptable devices. Unfortunately, development efforts have primarily focused on fingerprinting algorithms and artificial intelligence models, overlooking the potential of adaptable hardware solutions. This paper presents an analysis of a novel dynamic antenna setup designed to adapt to changing environments, providing an enhanced indoor positioning solution based on Bluetooth Low Energy (BLE) and Direction-of-Arrival (DoA) technology. The goal is to evaluate and improve upon a previous design, reduce the error, and enhance the feasibility, thus providing an accurate position of the moving device in many conditions for different scenarios. This approach provides a solution for positioning and coverage and an evolving solution over time that can adapt to other systems in continuously changing environments.
