Wireless testbeds are widely used in research and require scalability, modularity, and extendibility of the hardware and software. These needs can be achieved by using software-defined radios (SDRs). In the case of ultrahigh-frequency radio frequency identification (UHF RFID), SDR-based RFID readers have been developed and used as wireless testbeds for enhancements in UHF RFID systems. Significant research effort is focused on realizing SDRs. In addition, the testing industry responded to this demand with several commercial products. Researchers also review existing work on SDR-based RFID readers, which are used as wireless testbeds to enhance UHF RFID systems, particularly in the field of secure communication and passive localization of RFID tags.
