Where Can I Find Details About the Link-Timing Mechanism of Passive EPC Tags?

Posted By RFID Journal, 09.25.2015

For my project, I need to know the values of the timing—T1, T2, T3, etc. With EPC Class 1 Gen 2 RFID, there are no precise values for these link timings. So does that mean they are completely aleatory values, or are they specific for each tag?

I am not an RF engineer, but my understanding is that a reader determines the link timing in a passive ultrahigh-frequency (UHF) RFID tag based on the second generation Electronic Product Code standard. It communicates with the tag and informs it when to send packets of data. If any of our readers can provide additional details about the link-timing mechanism of passive EPC tags, they are invited to post information below.
