What is the Meaning of RTLS and How Does It Work?

RTLS (Real-Time Location System) is a system that uses wireless technologies like Bluetooth (BLE), RFID, Wi-Fi, or Ultra-Wideband (UWB) to continuously track and display the real-time position of objects or individuals within a physical space.

How RTLS Works (Step-by-Step)

1. Tags (Attached to Things)

• Small devices placed on assets, people, or equipment

• Emit signals at regular intervals

2. Anchors / Readers (Installed in the Environment)

• Fixed sensors deployed across the area

• Receive signals from tags

3. Positioning Engine (Core System)

• Signal strength (RSSI)

• Time of flight (ToF)

• Angle of arrival (AoA)

4. Software Platform (Visualization Layer)

• Displays real-time locations on a map/dashboard

• Enables alerts, analytics, and reporting

Different RTLS solutions use various signal measurement techniques such as:

• RSSI (Received Signal Strength Indicator)

• Time of Flight (ToF)

• Angle of Arrival (AoA)

These methods determine RTLS location with varying levels of accuracy and latency.
