UWB (or Ultra-wideband) asset tracking is fast becoming a force within the asset tracking arena. It benefits from greater accuracy as well as being able to determine height too.
Similar to Bluetooth, the Ultra-Wideband (UWB) technology gives devices the ability to determine their location when they are close to each other.
This means it may be used for a wide variety of location-based services, such as the indoor location of assets, wayfinding inside venues, as well as contextual notifications.
Indoor positioning with Ultra-wideband has some significant advantages: Firstly, the accuracy is 10-30 cm, which is considerably better than when working with Bluetooth (5-10 meters) or Wi-Fi (5-15 meters).
Also, latency time (i.e. the time between when the data is collected and uploaded) is very low with position requests of up to 100 times/second. Finally, with UWB tracking, height differences can be measured accurately which is not usually available with other tracking methodologies.
UWB tracking uses distance measurement via time-of-flight (abbreviated to ToF) to precisely measure location. The Detector listens for signals from the UWB Beacons attached to the assets being tracked.
The detector calculates the assets location based on how long it takes for pulses of radio wave signals to travel from the UWB Beacon to the UWB Detector. In this way, UWB asset tracking solution delivers precise indoor UWB positioning.
At present, UWB is the only commercially available wireless technology that delivers highly accurate and highly precise locations. UWB tracking delivers fine-ranging measurements, while also supporting high-level security to protect access credentials and data communications. In short, it provides a highly accurate and secure asset tracking option.
Asset tracking or locating systems are fast be surpassed by asset intelligence. The advent of Industry 4.0 and the data it provides is changing manufacturing forever.
Safe Distancing has reached renewed prominence with COVID and the need to maintain distance to inhibit its spread. But there are many other applications of this technology which are explored in the post.
