What Is RTLS (Real Time Location System) Technology?

Real-time location systems (RTLS) are systems specifically designed to locate a person or thing in real-time. It is a wide range of technology applied in various fields of asset management. However, its application varies with industries. Properly designed RTLS’s primary purpose is to track, locate, manage, and track real-time personnel. This allows companies to make informed decisions based on data collected from the system. Mostly, RTLS applies to industries such as mining and manufacturing but is very effective in healthcare settings. In this article, we will discuss the components of the RTLS system, application areas, and technologies that use this system.

RTLS System Components

The primary function of the RTLS system is to manage and track assets when they revolve around an internal facility. In this case, the RTLS server used can be called a GPS that provides the same location data in real-time. It is also able to track the history of assets and personnel. Although the application of RTLS varies, the components of software and hardware are identical.

  • Transmitters

The job of a transmitter is to identify a person’s object. It receives signals from recipients and responds with real-time data. The function of a transmitter, also called a transponder, badge, or tag is to send data about the location and identity of an object or person via a wireless signal.

  • Receivers

At the facility, receivers collect data from items about tagged people or their location. They can track the position of an item using tag proximity or triangulation.

  • Software

It is a management portal that retrieves data from recipients. Computers and operators can then analyze the data received.

Application Areas For RTLS Systems

  • Asset Tracking And Management

RTLS is an important system for tracking and managing assets in a company. Through wireless signals, the system can communicate with RFID readers within the company. The system has an access control system that allows a person to sign in or out of an asset.

  • Access Control

In this application, the system allows a worker or visitor to pass through security checkpoints. It records activity in designated areas. Therefore, employees or visitors can carry RTLS badges that allow them and provide real-time data of their current location.

  • Employee Tracking And Safety

RTLS is used to monitor the location and safety of workers and patients in healthcare settings. It also applies to high-security areas to monitor personnel health and safety. The system can monitor workers, lonely employees, or patients in hospitals in hazardous environments. It helps to participate effectively in emergencies.

  • Emergency Mobilization

Employees can wear RTLS badges with an emergency collection system that monitors their location in the event of an emergency evacuation. The company should have a meeting place where all the personnel should gather. The system then records existing employees to help identify at-risk individuals and their current location.

  • Network Security

With WPA in the system, it is possible to limit the Wi-Fi spread area from which the Wi-Fi user can communicate. In short, it limits access by user location.

What Technologies Does RTLS Use?
  • Passive and Active RFID

When we talk about RFID, we are talking about both active and passive. RTLS works in passive RFID when placed at the entrance or exit of a building. They get power when someone brings the tagged object closer to the meter. The tags are small and the price is low. Active RFID is similar to passive RFID although they are larger and more expensive.

  • Infrared

Infrared radiation, when combined with RTLS, is effective when you need or have room. If you want to identify the position of a particular asset in a room without having to manually search for it, IR with RTLS can help identify where the asset is, and it’s a low cost for an enterprise. Is a choice. It can send and receive signals from the tag on the asset and send the data to the computer.

  • Wi-Fi

When paired with RTLS, Wi-Fi access points can also be used to provide the real-time location of devices. They work with RFID in much the same way, although they are limited in proximity.


With RTLS, ultrasound waves can provide the right location at room level. The reason it is limited to the surface of the room is that the solid walls block the waves.

Final Thoughts!

From the details given above, you can see that RTLS is applicable in many fields. Whether you want room-level tracking or high-accuracy asset tracking and workplace safety, RTLS can provide the solution you need. You just have to be more discriminating with the help you toward many persons. It will provide real-time data on the location of your assets and staff to improve safety and security.
