标准范围

ISO/IEC 18000-2:20 09定义了工作在135 kHz以下的射频识别（RFID）设备的空中接口。ISO/IEC 18000-2:20 09的目的是为RFID设备提供通用技术规范，可供制定RFID应用标准的ISO委员会使用。ISO/IEC 18000-2:20 09旨在允许兼容性并鼓励国际市场上产品的互操作性。ISO/IEC 18000-2:20 09定义了用于在询问器和标签之间通信的物理层，并且进一步定义了在空中接口中使用的通信协议。ISO/IEC 18000-2:20 09定义了两种类型的标签:A型和B型，其区别仅在于它们的物理层。两者都支持相同的清单（防冲突）和协议。A型标签由询问器永久供电，包括在标签期间-到询问器传输，并在125 kHz下工作。B型标签由询问器供电，除了在标签到询问器的传输期间，并且在125kHz或134.2 kHz下工作。

ISO/IEC 18000-2:2009 defines the air interface for radio frequency identification (RFID) devices operating below 135 kHz. The purpose of ISO/IEC 18000-2:2009 is to provide a common technical specification for RFID devices that can be used by ISO committees developing RFID application standards. ISO/IEC 18000-2:2009 is intended to allow for compatibility and to encourage inter-operability of products in the international marketplace. ISO/IEC 18000-2:2009 defines the physical layer used for communication between the interrogator and the tag and further defines the communications protocol used in the air interface.

Two types of tag are defined by ISO/IEC 18000-2:2009: Type A and Type B, which differ only by their physical layer. Both support the same inventory (anti-collision) and protocol.

Type A tags are permanently powered by the interrogator, including during the tag-to-interrogator transmission, and operate at 125 kHz.

Type B tags are powered by the interrogator, except during the tag-to-interrogator transmission, and operate at 125 kHz or 134,2 kHz.
