The RSSI-based method for Indoor/outdoor Proximity Tracking

The Sentrax employs a variety of techniques and methods to approximately locate and track assets, inventory, and personnel within facilities. Among the popular technologies in indoor positioning and tracking, the Bluetooth RSSI-based (Received Signal Strength Indicator) stands out for its ability to provide detailed insights into signal strength within environments. Proximity
sensing comes with several benefits with cost-effective live monitoring of goods, easy deployment, and accuracy of several meters with dense deployment۔

Bluetooth RSSI Indoor Positioning and Tracking: How it is used?

Indoor positioning and tracking solutions are becoming increasingly critical across various sectors, including retail, healthcare, logistics, and smart buildings. In this context, the Received Signal Strength Indicator (RSSI) is a key parameter for estimating the location of BLE (Bluetooth Low Energy) devices within indoor spaces. The simplicity of the RSSI-based method contributes to its widespread adoption, as it can be applied to almost any device using wireless communication technologies. Distance calculation relies on the differences in packet arrival times at different receivers and involves measuring the signal strength of the received packets. This method is commonly used to determine the distance between a transmitter and a receiver by observing the decrease in signal strength as the signal moves away from the transmitter.

Whether used in a large warehouse or a small retail store, the principles of Bluetooth RSSIbased tracking are straightforward. To effectively track all necessary assets within a facility, the following components of the system must be in place:

• Devices such as tags capable of transmitting BLE signals.
• Dedicated receivers or gateways designed to receive signals from the tags.
• Specialized RTLS (Real-Time Location System) software, such as the Solix RTLS and IoT Management Platform, which can process all collected data and present it in an easily understandable format.
