• The symbol, T=>R, refers to commands or communications signal air interface from a tag to an
interrogator (tag-to-reader).
6 Requirements: Physical layer, collision management system and protocol values
for 13,56 MHz systems
6.0 General and applicable to All Modes
6.0.1 Presentation as determined in ISO/IEC 18000-1
The context, form and presentation of this part, which provides physical layer, collision management system
and protocol value definitions for RFID systems for item identification operating at 13,56 MHz are in
accordance with the requirements of ISO/IEC 18000-1.
6.0.2 ISO/IEC 18000-3 Interoperability
This part of ISO/IEC 18000 specifies three MODES of operation at 13,56 MHz
These MODES are not interoperable, but they are expected to operate without causing any significant
interference with each other. Any known causes of interference are listed in Annex O.
NOTE 1 It is recommended that users select one MODE for any specific application.
NOTE 2 Local national regulations may further limit either power, frequency or bandwidth allocations and such
limitations may reduce the capability of a system within that country. Users shall have the responsibility to ensure that they
use only systems that comply with these regulations. This implies a user responsibility to obtain proofs from manufacturers,
and where appropriate have adequate tests carried out to assure that systems are in compliance.
NOTE 3 At the time of preparation of this part of ISO/IEC 18000, the interrogator to tag link and tag to interrogator link
physical layer emissions may be subject to type approval or certification. It is therefore necessary to make reference to
local or regional radio regulations and radio standards in addition to this part of ISO/IEC 18000. All systems are required to
comply with local radio regulations, which may affect performance.
6.0.3 ISO/IEC 18000-3 interrogator conformance/compliance
To claim compliance with this part of ISO/IEC 18000, an interrogator/ reader shall support either MODE 1,
MODE 2, or MODE 3. The interrogator may support any or all modes as an option (the modes are not
interoperable).
6.0.4 ISO/IEC 18000-3 tag compliance
To claim compliance with this part of ISO/IEC 18000, a tag shall support either MODE 1, MODE 2, or MODE 3.
The tag may support any or all modes as an option (the modes are not interoperable).
6.0.5 Command structure and extensibility
Clauses 6.1, 6.2, and 6.3, include definition of the structure of command codes between an interrogator and a
tag and indicate how many positions are available for future extensions. Command specification clauses
provide a full definition of the command and its presentation. Each command is labelled as being “mandatory”
or “optional”. In accordance with ISO/IEC 18000-1, the clauses of this part of ISO/IEC 18000 make provision
for “custom” and “proprietary” commands.
The types of permitted command options are defined in subclauses 6.0.6 to 6.0.9.
6.0.6 Mandatory commands
A mandatory command shall be supported by all tags that claim to be compliant. Interrogators which claim
compliance shall support all mandatory commands.
