Calibration Method Research And Device Setup For RFID Testers

While the Internet of Things is rapid developing in global world,the radio frequency identification(RFID)technology,which is one of the technologies in the Internet of Things,plays a huge role in transportation,retail,logistics and other fields.But for the RFID devices,no calibration specifications or verification regulation for RFID testers have been released,nor any calibration devices for RFID testers established.The corresponding GB standards are mainly for RFID products,but not for RFID testers.So there is an urgent need to study RFID tester calibration methods and experimental devices.This paper discusses the calibration situation of RFID technology in measurement domain,then describes the classification and technical standards of RFID technology.We make much research on the specification and testing requirements for RFID products in the international standards on the basis of the above,and define the calibration parameters for RFID testers.By making full use of existing instruments of Shanghai Institute of Measurement and Testing Technology,we establish the calibration devices for RFID testers.Finally,the calibration methods of important calibration parameters are analyzed.The suggestions on measurements are given according to the uncertainty analysis results and data analysis results,which are used in national technical specifications “Calibration Specification for Radio Frequency Identification(RFID)Testers”.
