24、, providing an air interface implementation for wireless, non-contact information system equipment for item management applications. Typical applications operate at ranges greater than one metre.The RFID system includes a host system and RFID equipment (interrogator and tags). The host system runs a
25、n application program, which controls interfaces with the RFID equipment. The RFID equipment is composed of two principal components: tags and interrogators. The tag is intended for attachment to an item, which a user wishes to manage. It is capable of storing a tag serial number and other data rega
26、rding the tag or item and of communicating this information to the interrogator. The interrogator is a device, which communicates to tags in its RF communication range. The interrogator controls the protocol, reads information from the tag, directs the tag to store data in some cases, and ensures me
27、ssage delivery and validity. This system uses an active tag.RFID systems defined by this part of ISO/IEC 18000 provide the following minimum features: identify tag in range; read data; write data or handle read-only systems gracefully; selection by group or address; graceful handling of multiple tag
28、s in the field of view; error detection.This part of ISO/IEC 18000 consists of two modes, Base and Extended. The following simplified differences should be drawn between the two modes: Base Mode defined in clause 6 is backwards compatible and includes all features described in the last revision of t
29、his part of ISO/IEC 18000 (ISO/IEC 18000-7:2009) with the addition of security features as described in clause 6.7. Extended Mode defined in clause 7 is new to this part of ISO/IEC 18000. Extended Mode presents a new communication protocol stack (PHY, MAC and Application layers) and provides an exte
30、nded feature set that addresses more complex user and deployment requirements.Substantive differences exist between Base Mode and Extended Mode across all layers of the communication protocol (PHY, MAC and Application). However, both modes may co-exist in any given physical environment.All parties a
31、re directed to consider carefully their use model before determining the most appropriate mode.The International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) draw attention to the fact that it is claimed that compliance with this document may involve the
32、 use of patents concerning radio frequency identification technology.ISO and IEC take no position concerning the evidence, validity and scope of these patent rights.The holders of these patent rights have assured ISO and IEC that they are willing to negotiate licences under reasonable and non-discri
33、minatory terms and conditions with applicants throughout the world. In this respect, the statements of the holders of these patent rights are registered with ISO and IEC.

36、 PreambleThe preamble shall be comprised of twenty (20) cycles of 60 s period, 30 s high and 30 s low, followed by two final level changes which identifies the communication direction: 42 s high, 54 s low (tag to interrogator); or 54 s high, 54 s low (interrogator to tag). Refer to Figure 2 above.6.

All
42、 derived application standards shall share the same physical layer protocols, but their command/response structure/field and command sets may vary depending on the application. The three basic commands (“Collection with Universal Data Block”, “Sleep” and “Sleep All But”) defined in this part of ISO/
43、IEC 18000 shall be supported by all derived application standards. All other commands required by this part of ISO/IEC 18000 shall be supported by this part of ISO/IEC 18000 compliant products, but not necessarily by products compliant with derived application standards.When the interrogator sends o

In the event that the interrogator wants to inventory all the active tags within its range, it sha
45、ll send out a Collection command as defined in this part of ISO/IEC 18000. All tags adhering to this part of ISO/IEC 18000 or derived application standards shall respond to this basic Collection command. A tag shall respond with the collection response defined by the tags own application data link l
