Indoor Positioning Using infsoft UWB Tags

infsoft UWB Tags are small modular components using Ultra-wideband (UWB) that enable tracking objects and vehicles indoors and are also suitable for analyzing walking routes. They are typically used in server-based procedures, which means that the position is determined on a server (cloud).

Functionality of infsoft UWB Tags

server- and client-based indoor positioning using infsoft Ultra-wideband (UWB) Tag

infsoft UWB Tags can be used in different application scenarios. Ultra-wideband enables asset tracking in industrial environments with an accuracy of 10-30 cm.

Based on the Time Difference of Arrival (TDoA) method, the position of the UWB tag is determined using a measurement of time differences. The UWB tag sends signals to installed infsoft Locator Nodes 1100 in the environment. The distance between the tag and the Locator Nodes 1100 is calculated based on the signal run time. Since the distance between the Locator Nodes and the tag varies, the signal reaches each Locator Node at a different time. These time differences are the basis for the multilateration calculation used to determine the position of the UWB Tag. As a crucial factor, all Locator Nodes require direct line-of-sight, as they have to synchronize with each other.

The system can either be set up in a server-based (visualization of positioning data in the backend, no display on a client (smartphone)) or client-based approach (visualization of positioning data on a client (smartphone) and, if necessary, transmission to the backend).

Use Cases for Indoor Positioning with infsoft UWB Tags

infsoft UWB Tags enable some exciting use cases in many different industries. Here are some examples:

The infsoft UWB Tag can be supplied with power over the vehicle. The evaluation shows which areas have been cleaned how many times.

Software solution used: Indoor Tracking, Indoor Analytics
Sensors used: Bluetooth Low Energy (beacons), Ultra-wideband

The tugger train to be pursued is equipped with an infsoft UWB Tag, which passes the geo data via Bluetooth or USB interface to the driver's smartphone. There, the position can be displayed in a map and can be linked via return channel to a location-based task management.

Software solution used: Indoor Tracking, Indoor Navigation
Sensors: Ultra-wideband
Example of use: Process Optimization in Automotive Manufacturing
