A RFID-Based Smart Shelving Storage System in UHF band is presented for localization of tagged items with specific reference to a pharmacy drawer for drug storage. Employing RSSI (Received Signal Strength Indicator) information during drawer opening and closing movements, a classification of the tagged item is achieved. During drawer movements, the relative position of tag and reader antenna changes, so allowing for uncorrelated RSSI measurements to exploit with a linear classifier. Measurements in a real scenario are carried out with commercial tags and reader antennas. Location performance is presented in terms of the probability of making a correct decision. © 2012 IEEE.

Abstract
A RFID-Based Smart Shelving Storage System in UHF band is presented for localization of tagged items with specific reference to a pharmacy drawer for drug storage. Employing RSSI (Received Signal Strength Indicator) information during drawer opening and closing movements, a classification of the tagged item is achieved. During drawer movements, the relative position of tag and reader antenna changes, so allowing for uncorrelated RSSI measurements to exploit with a linear classifier. Measurements in a real scenario are carried out with commercial tags and reader antennas. Location performance is presented in terms of the probability of making a correct decision. © 2012 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
