Indoor Positioning with infsoft Locator Tags

infsoft Locator Tag

infsoft Locator Tags are small BLE and UWB tags which enable capturing and tracking objects and people indoors. They are also suitable for analyzing walking routes. Much like infsoft Locator Nodes, they work with server-based installations, which means that the position is determined on a server (cloud or on-premise). In contrast to infsoft Locator Nodes, infsoft Locator Tags are primarily developed for large areas where only a few objects should be captured using BLE.

infsoft Locator Tags are modularly constructed and can be equipped with BLE and Ultra-wideband modules - depending on the application scenario. Thus, they are suitable for Ultra-wideband applications.

For indoor positioning with infsoft Locator Tags, evenly distributed beacons are necessary. Since beacons are relatively cheap (3-30 Euros) and easy to install (can be glued to walls/ceilings, battery-powered), they are especially suitable for large areas with just a few items to track. The tag itself is inexpensive, battery-powered and roughly has the size of a matchbox. It is adhered to the object, people who should be tracked, can simply put it into their pockets.

The infsoft Locator Tags receive the Bluetooth signals of the beacons installed in the building and transmit the data via WiFi to the infsoft LocAware platform®. Here, the position is calculated and provided via web services. The beacons can be used for precise indoor navigation for employees and clients independently. In order to make use of indoor navigation, an app is necessary. Hence, infsoft Locator Tags are suitable for all scenarios where a few objects should be tracked in a large area and indoor navigation is an interesting additional feature.


Functionality of infsoft Locator Tags with Ultra-wideband Module

infsoft Locator Tags are designed to fit our client's specific needs. This is why they can be equipped with various modules. So they can be used in a very flexible way and can be changed according to current requirements. Besides BLE, Ultra-wideband is one possible module. UWB enables asset tracking in industrial environments with an accuracy of 10-30 cm.

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

Use Cases for Indoor Positioning with infsoft Locator Tags

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

In a large clinic, certain medical devices such as a mobile X-ray machine can be tracked. In addition, patients benefit from indoor navigation.

Software solution used: Indoor Tracking, Indoor Navigation
Sensors used: Bluetooth Low Energy (beacons)
Example of use: Positioning of Medical Equipment in a Clinic


The walking routes of guardians can automatically be tracked on a large factory site, if the guards are equipped with a locator tag.
Software solution used: Indoor Tracking
Sensors used: Bluetooth Low Energy (beacons)

The Locator 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 forklift to be pursued is equipped with an infsoft locator 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 order management.

Software solution used: Indoor Tracking, Indoor Navigation
Sensors: Ultra-wideband
Example of use: Tracking and Navigation of Floor Conveyors in Industrial Environments
