Evaluation of the Effect of Gen2 Parameters on the UHF RFID Tag Read Rate

The UHF RFID technology is nowadays widely spreading in different industries, e.g. in the supply chain and warehouse management of different goods among others. This paper presents passive UHF RFID tag read rate measurements using the EPCglobal Class 1 Gen 2 protocol. Tag encoding schemes such as FM0 and Miller, and Gen2 parameters such as Tari and Backscatter Link Frequency are varied to find out their effect on the tag's reading rate. Relating to these parameters alterable in the tag reader, this paper provides certain achievements which can be exploited in industrial RFID configurations and setups.
