碩士 === 國立中正大學 === 通訊工程學系 === 98 === Radio frequency identification (RFID) is an automatic identification system using the radio frequency based on non-contact transmission between the interrogator and tags to reach target sensing and exchange information. We will discuss the EPC Class-1 Generation-2 (EPC C1G2) RFID Specification defined in the air interface, of which the class-1 RFID systems communicate at carrier frequencies of 860MHz to 960MHz. For tag identification, the system should at least provide the following features: an electronic product code (EPC) identifier, a tag identifier (TID), a ‘kill’ function that can permanently disable the tag, an optional password-protected access procedure, and an optional user memory. This thesis discusses the information exchanged between the interrogator and tags. In addition, information transfer procedures are divided into two sections and are explained in detail. Furthermore, management of tag populations by the method of sessions A and B symmetry will be explained in detail.
