High-Rate Wi-Fi Asset Tracking for Logistics Hubs
The challenge
Retail distribution hubs had extensive Wi-Fi infrastructure but lacked methods to effectively use it for high-rate asset tracking. Accuracy and update frequency were insufficient for rapid conveyor-to-pallet handoffs, especially in environments with heavy metal and dense RF noise. This demanded a robust solution built through expert product engineering.
What we built
EurthTech deployed an augmented Wi-Fi tracking solution that uses existing enterprise APs plus Edge AI embedded systems collectors. Trackers operate as Wi-Fi clients that periodically probe and send compressed telemetry over a low-power fallback (like BLE). This hybrid approach avoids massive AP configuration changes while providing frequent location updates and loss-detection events, supporting a crucial Predictive maintenance AI IoT strategy for material handling equipment.
How it works
The tags use Wi-Fi chipsets in light client mode with embedded systems development focused on scan-window optimization and accelerometer-triggered bursts. Edge collectors perform local fingerprint matching against a pre-built RSS map when latency is a concern, ensuring rapid updates to floor operators. Server-side smoothing uses particle filters to cope with noisy RSS distributions, utilizing AI GIS analytics to achieve aisle-level granularity and provide per-zone heatmaps and anchor health indicators.
Results
In a distribution hub pilot, the system provided frequent location updates with a median error of ~4.0 m, meeting operational needs. Search times for misplaced totes dropped by 55%, and conveyor handoff errors reduced due to better upstream visibility.
Scalability & Digital Twin: The platform used hashed/ephemeral device IDs for privacy and partitioned topic streams Kafka for scaling. By accurately digitizing every asset's movement and dwell time, the data forms the basis for a high-fidelity Digital twin smart city logistics model, allowing for simulation and workflow automation—a key capability of our GIS consulting company expertise.
