Asset Tracking and RTLS Glossary

Asset Tracking

In a business context, asset tracking refers to a company keeping physical tabs on its assets. Or, put simply, using a tracking device to identify the physical location of different objects.


Interferometry is based on wireless propagation. Wireless propagation in space is very useful for location tracking - RADAR is a good example.


Radio Frequency Identification (RFID) is a technology that employs electronic labeling using radio waves. The fundamental concept involves small devices known as tags, which are attached to objects for identification purposes. These tags store information that can be wirelessly read by a compatible device using radio waves.

Chain of Custody

Chain of custody refers to the process of tracking a product from its initial source as raw materials through to its final destination, whether that is the end user or retailer.

Internet of Things (IoT)

The Internet of Things (IoT) is the network of physical items that use sensors, software, and wireless devices to connect and communicate with each other.

Real-Time Location System (RTLS)

A real-time location system is a technology-based solution that tracks and monitors the exact location of a given item or asset.

Digital Twin

A digital twin is a computerized version of a physical object, space, or system. Computer software that generates a virtual replica of a real-life item makes it easy to visualize what a finished product, building, or complex system would look like and/or how it would respond to various conditions. 

Location Data

Location data is information about the geographical position of a device at a specific time. Devices may be standalone such as a smartphone that can collect and transmit data about its whereabouts.


Wi-Fi refers to a wireless technology that enables mobile and stationary devices (smartphones, tablets, personal computers, IoT gadgets, etc.) to connect to local networks and the Internet, often for free.
