Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
ISO/IEC 18000-7 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 31, Automatic identification and data capture techniques.

ISO/IEC 18000-7:2008(E)
Introduction
This part of ISO/IEC 18000 is intended to address RFID devices operating in the 433 MHz frequency band,
providing an air interface implementation for wireless, non-contact information system equipment for Item
Management applications. Typical applications operate at ranges greater than one meter.
The RFID system includes a host system and RFID equipment (interrogator and tags). The host system runs
an 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 regarding 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 message 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 tags in the field of view;
• error detection.
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 use of a patent
concerning radio frequency identification technology given in 6.2. ISO and IEC take no position concerning the
evidence, validity and scope of this patent right.
The holder of this patent right has assured ISO and IEC that he is willing to negotiate licenses under
reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect,
the statement of the holder of this patent right is registered with ISO and IEC. Information may be obtained

6.2 Data link layer
6.2.1 General
Data between interrogator and tag shall be transmitted in packet format. A packet shall be comprised of a
preamble, data bytes and a final logic low period. The last two pulses of the preamble shall indicate the end of
the preamble and beginning of the first data byte. The same two pulses of the preamble also indicate the
originator of the data packet. Data bytes shall be sent in Manchester code format. Transmission order shall be
most significant byte first; within a byte, the order shall be least significant bit first. Figure 2 illustrates the data
communication timing of the preamble and the first byte of a packet.
Note: Data byte transmitted order is most significant byte first; with a byte the order is least significant bit first. Byte shown
is code 0x64.
Figure 2 — Data communication timing
6.2.2 Preamble
The preamble shall be comprised of twenty pulses of 60 µs period, 30 µs high and 30 µs low, followed by a
final sync pulse which identifies the communication direction: 42 µs high, 54 µs low (tag to interrogator); or
54 µs high, 54 µs low (interrogator to tag).
6.2.3 Data byte format
Data bytes shall be in Manchester code format, comprised of 8 data bits and one stop bit. The bit period shall
be 36 µs, the total byte period shall be 324 µs. A falling edge in the centre of the bit-time indicates a 0 bit, a
rising edge indicates a 1 bit. The stop bit is coded as a zero bit.
6.2.4 CRC bytes
A CRC checksum shall be calculated as a 16-bit value, initialized with all zeroes (0x0000), over all data bytes
16 12 5
(excluding preamble) according to the CCITT polynomial (x + x + x +1). The CRC shall be appended to
the data as two bytes. Reference: ITU-T Recommendation V.41 (Extract from the Blue Book), Code-
independent error-control system, Appendix I - Encoding and decoding realization for cyclic code system.
6.2.5 Packet end period
A final period of 36 µs of continuous logic low shall be transmitted after the last Manchester encoded bit within
the packet.

The Packet Options field, described in Table 3, shall be is used to indicate the presence of the Tag serial
number and Tag manufacturer fields within the current data packet. If the interrogator wishes to address a
single tag by specifying its Tag serial number, Bit 1 of the Packet Options field shall be set, indicating point-to-
point communication. In the case in which the interrogator wants to address all tags within its RF
communication range, Bit 1 of the Packet Options field shall be cleared to indicate a broadcast message. A
broadcast message shall not use the Tag serial number field, which is omitted from the data packet. Reserved
bits are for future use. The default value shall be “0”.
6.2.6.2 Protocol ID
The protocol ID field allows different application standards based on ISO/IEC 18000-7 (“derived application
standards”) to be developed. All 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
two basic commands “collection” (i.e., collection with Universal Data Block)” and “sleep and sleep all but”
defined in this standard shall be supported by all derived application standards. All other commands required
by this standard shall be supported by 18000-7 compliant products, but not necessary by products compliant
with derived application standards.
When the interrogator sends out a wake up signal, all tags based on the ISO/IEC 18000-7 air interface and
derived standards shall wake up.
The interrogator may send out various commands as specified by the application. In the event that the
interrogator wants to inventory all the active tags within its range, it shall send out a Collection command as
defined in this standard. All tags adhering to ISO/IEC 18000-7 or derived application standards shall respond
to this basic Collection command. A tag shall respond with the collection response defined by the tag's own
application data link layer standard (ISO/IEC 18000-7 or derived standard). The tags shall also accept the
Sleep commands defined in this standard. The co-existence of ISO/IEC 18000-7 and derived standards is
illustrated in Annex A.
In this standard, the collection command is Collection with Universal Data Block. In the following section,
collection command and Collection with Universal Data Block are used interchangeably.

ISO/IEC 18000-7:2008(E)
6.2.6.3 Tag Manufacturer ID
The Tag Manufacturer ID is a unique identifier that is issued to each tag manufacturer. The Tag Manufacturer
ID is a 16-bit code assigned by the Registration Authority as called out in ISO/IEC 15963. This 16 bit code is a
combination of the 15963 Allocation Class “0001 0001” and the 8-bit Issuer UID “xxxxxxxx”.
6.2.6.4 Tag Serial Number
The Tag Serial Number is a 32-bit integer that is uniquely assigned to each individual tag during
manufacturing. This number cannot be changed and is read only. The Tag Serial Number has no structure
and does not contain any information besides uniquely identifying a tag. The Tag Serial Number cannot be
reused. Issuance of Tag Serial Numbers may be managed and administered by each manufacturer. The Tag
Manufacturer ID and Tag Serial Number together uniquely identify a tag as defined in ISO/IEC 15963. The
Tag Serial Number for each manufacturer is four bytes in length. An example of the combined data structure
for Tag Manufacturer ID and Tag Serial Number is:
00000001 00010001 xxxxxxxx xxxxxxxxx xxxxxxxx xxxxxxxxx
6.2.6.5 Interrogator ID
The Interrogator ID is a 16-bit integer programmed into the interrogator's non-volatile memory. The
Interrogator ID, which can be changed without restriction, is used to route tag responses efficiently through an
interrogator network. At the moment the Interrogator ID is changed in an interrogator, any ongoing
communication between that interrogator and any tag shall be terminated. An interrogator that receives a tag
message containing an Interrogator ID not equal to the Interrogator ID of that interrogator shall not pass the
message to the system.
6.2.6.6 Command codes
The Command codes and their function as a Read and/or Write command shall be as listed in Table 4, below.
The least significant 7 bits of a command identify its base function; the eighth (MS) bit is set to “0” for a Read
function and “1” for a Write function. Codes not identified are reserved. All commands are mandatory unless
otherwise specified.
