UWB Indoor Positioning: Centimeter-Accurate Location Tracking
How Ultra-Wideband (UWB) delivers 10–30cm indoor accuracy, where it beats BLE, and the best use cases for precise positioning.
When room-level accuracy is not enough, Ultra-Wideband (UWB) delivers 10–30cm indoor positioning. UWB is the technology behind precise asset tracking, collision avoidance and secure access. Here is how it works and where it excels.
How UWB works
UWB measures the time-of-flight of very short radio pulses between anchors and tags. Because it uses timing rather than signal strength, it is far more accurate and resistant to interference than BLE or Wi-Fi positioning.
UWB vs BLE
- Accuracy: UWB 10–30cm vs BLE 1–5m
- Cost: UWB higher per anchor/tag
- Latency: UWB very low (real-time)
- Best for: UWB precision zones; BLE broad low-cost coverage
Top use cases
Forklift-pedestrian collision avoidance, precise tool and equipment tracking, secure hands-free access, and process automation where exact position triggers actions.
Deploy UWB with TechNexusGen
We design UWB anchors and tags, tune the location engine, and often blend UWB (precision zones) with BLE (broad coverage) for cost-effective, accurate indoor positioning.
