Title: Next-Generation Signals and Architectures for High-Precision Indoor Positioning Systems
Abstract:
This presentation provides a comprehensive analysis of the paradigm shift in Indoor Positioning Systems (IPS) spanning the 2024–2026 technological period. Moving beyond traditional, low-accuracy proximity tracking, the industry is transitioning toward deterministic, high-precision spatial intelligence. The study examines the architectural evolution and commercial deployment of key signaling technologies, including Wi-Fi Sensing (IEEE 802.11bf) and Wi-Fi 8, Bluetooth 6.0 Channel Sounding, and Ultra-Wideband (UWB) for micro-location. Furthermore, it explores macro-level cellular innovations such as 5G-Advanced, Ambient IoT, and the impending 6G Integrated Sensing and Communication (ISAC) framework. Niche but critical non-RF modalities—including acoustic positioning, Light Fidelity (Li-Fi), and geomagnetic fusion—are also evaluated. By synthesizing standardization timelines, hardware ecosystem maturity, and comparative performance metrics, this presentation concludes that the future of spatial intelligence is fundamentally hybrid, heavily reliant on artificial intelligence, and essential for modern enterprise operations.
