Ultra-Wideband (UWB) Tracking

GM of Operations

Published 2 May 2026

Ultra-wideband tracking uses short-duration radio pulses to locate tagged assets with 10 to 30 centimetre accuracy indoors, far exceeding the precision of Bluetooth or Wi-Fi positioning systems.

Ultra-wideband tracking is a real-time location system (RTLS) technology that uses short-duration, low-power radio pulses across a wide frequency spectrum to determine the precise position of tagged assets within an indoor or bounded environment. UWB achieves location accuracy of 10 to 30 centimetres, significantly better than Bluetooth (1 to 3 metres) or Wi-Fi (3 to 5 metres) based systems. UWB tags transmit pulses that are received by fixed anchors installed around the tracked area, and the system calculates position using time-of-flight or time-difference-of-arrival measurements. UWB has gained adoption in manufacturing, automotive assembly, logistics, healthcare, and mining where high-precision location data is required for safety zones, process automation, and collision avoidance. Recent integration of UWB into smartphones and wearable devices is also expanding its accessibility beyond dedicated industrial RTLS installations. Unlike Bluetooth and Wi-Fi positioning, which rely on signal strength measurements that are easily distorted by environmental factors, UWB timing-based measurements are inherently more resistant to multipath interference from metal structures, machinery, and other reflective surfaces common in industrial environments.

Why it matters

Applications that require precise indoor positioning, such as automated guided vehicle navigation, collision avoidance between workers and mobile equipment, and high-value tool tracking in assembly environments, cannot achieve adequate performance with lower-accuracy technologies. UWB fills this gap by providing real-time, centimetre-level accuracy without the line-of-sight limitations of optical systems. For safety-critical applications such as proximity warning in mining and construction, the accuracy and low latency of UWB can be the difference between effective hazard alerting and a system that generates excessive false alarms.

How MapTrack helps

MapTrack integrates with UWB infrastructure to ingest high-precision location data, combining it with asset records, maintenance history, and compliance data in a single dashboard that provides full operational visibility across every tracked zone.

Frequently asked questions

How accurate is UWB tracking compared to Bluetooth and GPS?

UWB achieves 10 to 30 centimetre accuracy in ideal conditions, compared to 1 to 3 metres for Bluetooth Low Energy and 3 to 10 metres for GPS (outdoors only, with no indoor capability). This makes UWB the most accurate option for indoor real-time location. However, UWB requires dedicated anchor infrastructure and is more expensive per coverage area than Bluetooth-based solutions.

What infrastructure is required for UWB tracking?

A UWB RTLS requires fixed anchor devices installed around the coverage area (typically every 20 to 50 metres depending on the environment), UWB tags attached to assets or worn by personnel, a location engine server that processes the timing data and calculates positions, and network connectivity between anchors and the server. The anchors need power and, in most systems, Ethernet or Wi-Fi backhaul. Installation complexity is higher than BLE beacon systems but lower than active RFID portal infrastructure.

When should an organisation choose UWB over Bluetooth beacons?

Choose UWB when the use case demands high accuracy (sub-metre), low latency (near real-time position updates), or safety-critical applications such as collision avoidance and exclusion zone enforcement. Choose Bluetooth when zone-level accuracy (room or area) is sufficient, when the priority is low cost per tag, or when the tags need multi-year battery life with minimal infrastructure. Many large facilities deploy both technologies: UWB for high-value or safety-critical tracking and Bluetooth for broader asset visibility.

Related terms

RFID Tracking

RFID (Radio-Frequency Identification) tracking uses electromagnetic fields to automatically identify and track tags attached to assets. Passive RFID tags are powered by the reader’s signal and work at short range, while active RFID tags have their own power source and can transmit over longer distances. RFID enables hands-free, multi-item scanning without requiring line-of-sight to each tag.

GPS Tracking

GPS (Global Positioning System) tracking uses satellite signals to determine and record the real-time geographic location of assets, vehicles, or equipment fitted with GPS receivers. Tracking data is transmitted to a central platform via cellular or satellite networks, providing continuous visibility of asset movements, routes, and dwell times. GPS tracking is fundamental to fleet management and high-value mobile asset monitoring.

IoT Sensors

IoT (Internet of Things) sensors are connected devices that collect and transmit data about an asset’s condition, environment, or usage in real-time. Common sensor types measure temperature, vibration, humidity, fuel levels, engine hours, pressure, and tilt. The data is transmitted wirelessly to a central platform for monitoring, alerting, and analysis.

QR vs Barcode vs RFID vs GPS

QR codes, barcodes, RFID and GPS are the four common ways to identify and track a physical asset, and they trade off range, cost and what they tell you. A barcode is a printed 1D label read at close range with line of sight - the cheapest option, but it only identifies the asset, it does not locate it. A QR code is a 2D barcode that any smartphone camera can scan, holds more data, and can link straight to the asset record. RFID uses radio tags that a reader can pick up wirelessly, without line of sight, several tags at once - ideal for fast stocktakes, though it reports presence in a zone rather than a precise position. GPS uses a powered tracker to report real-time location anywhere outdoors, which is why it suits vehicles and mobile plant rather than a shelf of hand tools. Most operations end up using more than one: a printed QR or barcode for the register, and GPS on the assets that move.
