Radio Frequency Identification (RFID) revolutionised asset tracking by enabling automated identification and real-time inventory visibility. However, as logistics operations grow more complex and demand higher precision, complementary technologies like Ultra-Wideband (UWB) and Bluetooth Low Energy (BLE) are emerging as powerful solutions to address RFID’s limitations.
Why Look Beyond RFID?
While RFID offers benefits such as non-line-of-sight scanning and bulk reading, it faces challenges in accuracy, range, and interference — especially in crowded, metal-rich logistics environments. To meet the increasing demand for precise location tracking and detailed asset insights, logistics providers are turning to UWB and Bluetooth technologies.
Ultra-Wideband (UWB): Precision and Reliability
UWB operates by sending very short radio pulses across a wide frequency spectrum, enabling highly accurate location tracking with centimetre-level precision. This capability allows logistics companies to:
- Track assets in real time within warehouses and yards with exceptional accuracy.
- Navigate complex indoor environments where GPS falls short.
- Improve safety by monitoring equipment and personnel locations simultaneously.
UWB’s robustness against interference and multipath effects makes it ideal for harsh industrial settings.
Bluetooth Low Energy (BLE): Cost-Effective and Versatile
BLE tags provide a flexible and affordable option for asset tracking and proximity detection. Advantages include:
- Low power consumption enabling long battery life.
- Wide adoption and compatibility with smartphones and other Bluetooth-enabled devices.
- Seamless integration with IoT platforms for data analytics and asset management.
BLE is particularly useful for tracking smaller assets and enabling location-based services such as smart notifications and access control.
Complementing RFID: Hybrid Tracking Systems
Many logistics operators leverage hybrid solutions combining RFID, UWB, and BLE technologies to maximise benefits:
- RFID delivers efficient bulk identification and automated inventory.
- UWB provides pinpoint location accuracy for high-value or critical assets.
- BLE offers flexibility and cost efficiency for supplementary tracking.
This layered approach ensures comprehensive visibility, optimising supply chain operations end-to-end.
Real-World Applications
- High-value pallet and container tracking with UWB in crowded warehouses.
- Asset and personnel safety monitoring in logistics yards using UWB.
- BLE-enabled smart lockers and mobile asset tracking for last-mile delivery.
The Future of Asset Tracking in Logistics
As IoT ecosystems mature, integration of UWB and BLE with cloud analytics and AI-driven insights will further enhance supply chain agility, reduce losses, and enable proactive operational decisions.
