What Is An Indoor Position Tracking System?

Indoor position tracking system involves multiple devices connected over a network that aims at providing location tracing services for individuals and other holdings that cannot be traced via GPS or other location tracing systems such as satellites.

GPS and satellites are restricted to some extent and in some cases are unable to reach the location of the people or assets they wish to trace which can result in the provision of inaccurate results. That’s the reason why businesses have started adopting indoor positioning system Bluetooth as they can even provide results when the GPS fails. These systems are capable of tracking people and assets even at places where GPS and satellites fail to track.  

Most airports, remote workplaces, underground locations, mining sites, etc., tend to use indoor position systems as they provide a functional insight into the movement of assets and people. It provides real-time directions and can even reach places where GPS cannot. There are various types of Indoor Positioning System Technology such as:  

Proximity-based systems

These systems can trace the location of a person or thing at room level in a specified facility. They make use of beacons and tags for tracking purposes. 

Wifi based systems

In such systems, the wifi transmitters transfer simple and smaller packets to numerous wifi access points given in a particular facility. Accordingly, the strength and point of time when the signals were received is sent to the backend by the access points which is calculated based on the algorithms set for computing the position of the target. Further, the information is sent to the cloud regarding the location of the target.  

Ultra Wide Band systems

To use an indoor position tracking system, the area needs to be covered with UWB anchors for indoor purposes to create a local setup. The UWB system makes use of three or more than three wide-band readers that send a wide pulse over a huge spectrum in GHz. The chirps are then heard by the readers that come from the wide-band tags that have an exciter deployed in them capable of creating pulses that cause short and instantaneous bursts. Accordingly, the readers measure the reported time and send it back to the central server.  

Infrared systems

The IR system makes use of infrared rays or pulses to track the signals within a building premise. To read the IR tag pulses, the IR receivers are installed in every room which further reads the pulses and tracks the location of the object or individual.
