Real-Time UWB Asset Tracking (Simoldes)

Summary

This UWB-powered industrial asset tracking system delivers real-time, high-precision location tracking (10–30 cm accuracy) for factories and warehouses, solving equipment misplacement, workflow inefficiencies, and redundant asset usage. By integrating Ultra-Wideband (UWB) tags and anchors, the system enables continuous asset visibility where GPS fails indoors. Designed for low-maintenance, high-efficiency tracking, the smart battery-optimized tags last up to 20 months without recharging, minimizing operational disruptions. Google Cloud IoT and Firebase power a real-time telemetry pipeline, while AI-assisted anomaly detection and geofencing automation optimize asset utilization. The platform supports 1,000+ trackers per factory, streamlining cross-location asset transfers and global scalability. With a 28% reduction in equipment misplacement, a 6-month ROI, and predictive maintenance insights, the system has been successfully deployed across multiple factories, improving efficiency and reducing unnecessary asset redundancies.

Challenges

• Factories lacked real-time visibility into asset movement, leading to misplaced equipment (namely forklifts), inefficient workflows, and unnecessary redundancies.
• Need for centimeter-level precision in high-density industrial environments, where GPS is ineffective indoors.
• Battery life concerns – Traditional tracking systems required frequent recharging or battery swaps, adding downtime and operational costs.
• Scalability across multi-country factories – The system had to handle hundreds of assets per location, with seamless asset transfers between global factory networks.

Solution

• Ultra-Wideband (UWB) Precision Tracking – Deployed UWB anchors throughout facilities to achieve real-time tracking with 10–30 cm accuracy.
• Battery-Optimized Smart Tags – Implemented context-sensitive update rates, enabling up to 20 months battery life on a single replaceable cell, reducing maintenance efforts.
• Cloud-Enabled Asset Intelligence – Built a high-throughput data pipeline to stream telemetry data in real time while enabling historical analysis for predictive asset optimization.
• Automated Geofencing & Trigger Alerts – Integrated custom automation workflows, allowing automated inventory management and instant alerts when assets leave designated areas.
• Global Scalability & Cross-Factory Transfers – Designed the platform to support 1,000+ trackers per factory floor, enabling seamless asset management across international sites.

Impact

• 28% reduction in equipment misplacement, significantly improving factory workflow efficiency.
• 6-month ROI achieved by eliminating excess asset redundancy (namely forklifts) and reducing equipment retrieval delays.
• Enabled predictive maintenance analytics, extending asset lifespan and reducing unplanned downtime.
• Adopted across multiple factory locations and companies.
