标准简介：This part of ISO/IEC 18000 defines the air interface for radio frequency identification (RFID) devices operating
below 135 kHz used in item management applications. Its purpose is to provide a common technical
specification for RFID devices to allow for compatibility and to encourage inter-operability of products for the
growing RFID market in the international marketplace. This part defines the forward and return link
parameters for technical attributes including, but not limited to, operating frequency, operating channel
accuracy, occupied channel bandwidth, spurious emissions, modulation, duty cycle, data coding, bit rate, bit
rate accuracy, bit transmission order. It further defines the communications protocol used in the air interface.
This part contains two types. The detailed technical differences between the types are shown in the parameter
tables.
This part of ISO/IEC 18000 specifies
• The physical layer that is used for communication between the interrogator and the tag.
• The protocol and the commands
• The method to detect and communicate with one tag among several tags (“anti-collision”)
It specifies two types of tags: Type A (FDX) and Type B (HDX). These two types differ only by their physical
layer. Both types support the same anti-collision and protocol.
FDX tags are permanently powered by the interrogator, including during the tag-to-interrogator transmission.
They operate at 125 kHz.
HDX tags are powered by the interrogator, except during the tag-to-interrogator transmission. They operate at
134,2 kHz. An alternative operating frequency is described in Annex B.
An optional anti-collision mechanism is described in Annex D.
