RFID vs BLE vs UWB Tracking
choose by event and accuracy.
Passive RFID is suited to read events at controlled points. BLE includes signal-strength proximity systems and angle-of-arrival positioning systems, which require different locator layouts. UWB positioning also varies by architecture, including wired and wireless infrastructure. Compare the selected products against required events, update rates, installation constraints, and a representative pilot rather than assuming a universal accuracy or cost ranking.

SRS Networks is a nationwide IT infrastructure deployment partner headquartered in South San Francisco, California, serving multi-site enterprises across the 48 contiguous states, Alaska, and Hawaii since 1996. This page turns field-delivery requirements into a scope, comparison, and acceptance record a buyer can use.
RFID, BLE, and UWB decision matrix
| Technology | Operational strength | Infrastructure tradeoff |
|---|---|---|
| Passive RFID | High-volume portal and choke-point events | Reader fields require antenna design and tuning |
| BLE | RSSI proximity or angle-of-arrival positioning | Selected locator geometry, orientation, tag maintenance, and backhaul |
| UWB | Precise real-time positioning | Model-specific geometry, synchronization, commissioning, and power/backhaul |
Pallet movement favors RFID
A dock or conveyor creates a controlled event point. Passive tags need no battery, while antenna placement and RF containment decide read accuracy.
Distinguish BLE proximity from direction finding
RSSI uses received signal strength; angle-of-arrival systems use directional measurements and a positioning engine. Locator orientation and coordinates matter. Specify the selected method before setting installation or acceptance requirements.
Precise motion favors UWB
Validate the chosen UWB system with real materials, movement, obstructions, and update rates. Wired and wireless designs have different field requirements. Location tracking alone is not a safety-rated collision-prevention system; safety-control design needs its own qualified owner.
Primary technical references
Use the current project specification, adopted code, approved design, and manufacturer instructions for the final decision. These primary references explain the testing and planning basis used in this resource.
When this is not the right approach
Do not select a technology from an accuracy chart alone. Pilot the real tags, materials, speeds, geometry, interference, and software workflow before setting a facility-wide standard.

Passive RFID is suited to read events at controlled points. BLE includes signal-strength proximity systems and angle-of-arrival positioning systems, which require different locator layouts. UWB positioning also varies by architecture, including wired and wireless infrastructure.
