Applying RSSI filters for optimal RFID performance - RFID Arena: WHAT DOES THE RSSI VALUE TELL US AND WHAT IS IT GOOD FOR?
It's fairly simple. RSSI stands for "Received Signal Strength Indicator" and it tells us the strength of the signal sent from an RFID tag to an RFID reader. But for what do we use that information in real-life?
For estimating the distance between an RFID tag and an RFID reader
For identifying the movement direction of an RFID tag
For setting optimal reading and writing conditions
For analysing and optimizing the environment
For locating lost tags
