A novel method to improve the subcarrier frequency accuracy for UHF RFID sensing system
2021 IEEE International Conference on RFID (RFID)(2021)
摘要
This paper presents a novel method to improve the subcarrier frequency accuracy of tag chip for UHF RFID sensing system based on EPC global Gen2 protocol. By changing the tag's response to the Write command, the tag returns the subcarrier before returning the response specified in the protocol. In this way, a frequency calibration loop will be established between reader and tag. This method not on...
