How Does RFID RTLS Locate Personnel With Sub-meter Accuracy?
RFID location tracking – RTLS systems:
An RFID location tracking system provides companies with real-time data on the status and movement of employees. Such technology is built on the active RFID technology. It is a cutting edge way for businesses to maintain streamlined processes, yet is surprisingly simple in how it operates.
The Basics Of RTLS – RFID Location Tracking
There are two types of RFID tracking; a passive RFID or an active RFID tracker and locator system. Both systems work in similar ways to track movement, but they are set up in different ways. Litum IoT can help businesses set up one an active RFID locator and tracker that allows you the benefits of real-time monitoring and tracking of assets.
Passive RFID systems do not actively track movement in real-time. They can only track assets and people when they pass through a gateway or near a reader. The drawback to this kind of system is that it has a limited range. The tag is only powered by the radio signal that it receives from the RFID locator. Yet, its return signal is much weaker than that sent from an active RFID tag.
So, a passive system may only be able to trigger on tags up to 7 meters away. This is usually good enough to track when assets or people leave rooms, the building, or go to specific work areas.
Location Tracking – RTLS with Active RFID Systems
Active RFID location tracking systems are a little more exciting. They allow businesses to track the real-time movement of assets and people throughout a monitored area. Some systems can track tags up to 30 meters away with a location accuracy of within a few meters. Active tags can be set up with panic buttons for employees, and sensors for monitoring the workplace environment or equipment operation. This data is sent along with the location signal to the reader.
Active RFID location tracking uses powered tags, which contain an internal battery. This energy source allows the tag to send out a strong, continuous signal that an RFID tracker and locator can pick up. Most RFID tags have batteries that can provide power for weeks or months before needing to be recharged.
How This Data Makes It Onto Your Computer Screen
The information picked up by an RFID tracker and locator is sent to a computer containing Litum RFID location tracking system software. It interprets the data and displays it as a moving image on an overlay of the building map.
With the map screen open, you’ll be able to watch as the signals from active ID tags ping off locators throughout the building. These active RFID tags will be shown moving second-by-second around the floor.
Total Awareness Of Workplace Activities
Both passive and active RFID location tracking allows companies to get an intimate view of the goings on in different work areas. However, an active RFID tracking system allows companies to take asset monitoring to another level. From the manufacturing facility to the accounting office, you’ll know where employees are, what equipment is used, and where inventory goes instantly.
