Introduction to RTLS

Imagine having complete real-time visibility of assets, inventory, or even personnel within your operations. Real-Time Location Systems (RTLS) make this possible, offering businesses revolutionary capabilities to track, manage, and optimize their physical resources. 

What is RTLS (Real-time location Systems)?

At its core, RTLS is a technology that provides the real-time location of objects, people, or assets within a specific area using tags, sensors, and software. It’s a powerful tool leveraged across industries like healthcare, manufacturing, warehouse management, and more. This guide will break down RTLS, discuss its benefits, and explore how you can harness its full potential.

By the end of this article, you’ll have a comprehensive understanding of RTLS, its workings, and how it can transform business operations. 

How Does RTLS Work?

RTLS technology brings together a combination of tags, sensors, and software to determine the real-time location of assets, people, or objects. Curious about how it all fits together? Here’s a closer look at the key components that work together to make it possible:

Tags and Devices

The process starts with tags, which are attached to the items or individuals you want to track. Traditionally, these small devices send out signals containing both unique identifiers and location data. Tags can be either active, meaning they regularly transmit signals, or passive, meaning they only respond when prompted by a sensor.

Sensors or Beacons

Next, strategically placed sensors or beaconss come into play. These devices are positioned within the designated tracking area to pick up signals from the tags. Once the sensors receive this information, they send it along to the RTLS software for further processing.

RTLS Software

This is where the magic happens. The RTLS software acts as the system’s brain, analyzing the received signals with advanced algorithms. These algorithms can range from complex methods like Time Difference of Arrival (TDoA), which offers high precision, to simpler techniques like Received Signal Strength Indicator (RSSI) for broader, less specific location tracking.

Output and Interface

The processed data is delivered through a user-friendly interface, such as maps, dashboards, or integrated tools like computerized maintenance management systems (CMMS). This ensures the insights are clear, actionable, and ready to support your operations.

RTLS may utilize different wireless technologies, each suited for specific applications:

  • RFID: Cost-effective for identifying assets but limited by short range.
  • Wi-Fi: Useful for leveraging existing network infrastructure, often providing room- or floor-level accuracy.
  • Bluetooth Low Energy (BLE): Energy-efficient for proximity tracking, with improving accuracy.
  • Ultra-Wideband (UWB): Known for sub-meter accuracy and minimal interference, ideal for high-precision needs.

Comparison of RTLS and RFID

RTLS and RFID are both powerful tracking solutions, but they serve different purposes.

  • RFID

    • Static technology that detects tagged objects within a proximity of the reader.

    • Ideal for basic inventory tasks and batch scanning but lacks real-time capabilities.

  • RTLS

    • Dynamically tracks objects in real time, offering room or area-level visibility and actionable data.

    • Essential in environments like healthcare where continuous monitoring of assets, personnel, and operations is critical.

What is the History of RTLS?

Early Days (RTLS 1.0 – Early 2000s): 

RTLS technology emerged. These systems used simple tags but complex and expensive infrastructure, making installations labor-intensive and disruptive.

Transition Period (RTLS 1.5 – Early 2010s): 

BLE technology became mainstream, but cost and accuracy issues persisted, limiting practicality of these solutions. 

The Next Generation (RTLS 2.0 – Late 2010s):
Cognosos introduced an innovative solution with battery-operated tags and beacons, leveraging cloud technology and machine learning for precise, cost-effective, and efficient real-time tracking, marking a significant advancement in RTLS.

Benefits of RTLS for Asset Management
