A flexible software defined radio-based UHF RFID reader based on the USRP and LabView

Abstract

This paper presents a UHF RFID Reader designed for recognition and tracking in IoT domain. It is built by NI USRP software radio platform and NI LabVIEW with flexible physical/MAC layer parameters, which can be modified easily and monitored clearly from front panel of this Reader compared to commercial RFID Reader. Queried random number sequence from a commercial Tag can be detected within half meter using this UHF Reader. All designs of this Reader are based on EPC Gen-2 RFID protocol, any further research based on this Reader can be easily connected and tested with commercial Tags.
