RTLS operates by tagging objects or individuals with devices that emit signals. These signals are then captured by a network of receivers that calculate the tag’s location, often in real-time. The technology can be applied across numerous scenarios, from monitoring equipment in hospitals to enhancing guest experiences in hospitality by offering personalized services based on location.

In WiFi-based RTLS, the tags are usually WiFi-enabled devices such as smartphones, tablets, or specialized badges. The system utilizes the existing WiFi infrastructure, making it a cost-effective solution for businesses looking to implement or upgrade their location-tracking capabilities without the need for substantial additional investments in hardware.

Access Points

Access points (APs) play a crucial role in a WiFi RTLS setup. They act as the receivers that pick up the signals emitted by the tags. By measuring the strength of the signal from a device as it connects to multiple APs, the system can determine the device’s location with surprising accuracy. The more access points available, the more precise the location data.

How Routers Facilitate Indoor Positioning

Routers, while primarily known for providing internet connectivity, also contribute to the effectiveness of WiFi RTLS. They can serve as bridges between access points and the location engine, managing data traffic and ensuring that location information is processed efficiently. In some configurations, routers can function as access points, further extending the network’s reach and location-tracking capabilities.

The Process of Location Tracking

The process of location tracking in a WiFi RTLS involves several steps:

  • Detection: The system detects a signal emitted by a WiFi-enabled device.
  • Signal Measurement: Access points measure the signal strength and, in some cases, the angle of arrival (AoA) of the signal.
  • Data Aggregation: The measurements are sent to a location engine, which aggregates the data from multiple access points.
  • Location Calculation: Using algorithms, the location engine calculates the device’s position based on the aggregated data.
  • Application Integration: The calculated location is then integrated into various applications, enabling businesses to track assets, enhance security, improve customer service, and more.

WiFi RTLS stands out for its ability to leverage existing infrastructure, offering a blend of cost-effectiveness, scalability, and versatility. As businesses continue to seek efficient ways to manage resources and improve operations, WiFi RTLS emerges as a valuable tool in the digital transformation toolkit, seamlessly integrating with existing networks to provide comprehensive location-tracking solutions.
