Information technology — Radio frequency identification for item management — Part 63: Parameters for air interface communications at 860 MHz to 960 MHz Type C

This document defines the air interface for radio frequency identification (RFID) devices operating in the 860 MHz to 960 MHz industrial, scientific, and medical (ISM) band used in item management applications. It provides a common technical specification for RFID devices that can be used to develop RFID application standards. This document is intended to allow for compatibility and to encourage inter-operability of products for the growing RFID market in the international marketplace. It defines the forward and return link parameters for technical attributes including, but not limited to, operating frequency, operating channel accuracy, occupied channel bandwidth, maximum effective isotropic radiated power (EIRP), spurious emissions, modulation, duty cycle, data coding, bit rate, bit rate accuracy, bit transmission order, and, where appropriate, operating channels, frequency hop rate, hop sequence, spreading sequence, and chip rate. It further defines the communications protocol used in the air interface. This document specifies the physical and logical requirements for a passive-backscatter, Interrogator-Talks-First (ITF) systems. The system comprises Interrogators, also known as readers, and tags, also known as labels. An Interrogator receives information from a tag by transmitting a continuous-wave (CW) RF signal to the tag; the tag responds by modulating the reflection coefficient of its antenna, thereby backscattering an information signal to the Interrogator. The system is ITF, i.e. a tag modulates its antenna reflection coefficient with an information signal only after being directed to do so by an Interrogator. This document specifies — physical interactions (the signalling layer of the communication link) between Interrogators and tags; — logical operating procedures and commands between Interrogators and Tags; — the collision arbitration scheme used to identify a specific tag in a multiple-tag environment; — optional security commands that allow the use of crypto suites of ISO/IEC 29167.

Introduction
This document defines the physical and logical requirements for a passive-backscatter, Interrogator-
talks-first (ITF), radio-frequency identification (RFID) system operating in the 860 MHz to 960 MHz
frequency range. The system comprises Interrogators, also known as Readers, and Tags, also known as
Labels or Transponders.
An Interrogator transmits information to a Tag by modulating an RF signal in the 860 MHz to 960 MHz
frequency range. The Tag receives both information and operating energy from this RF signal. Tags are
passive, meaning that they receive all of their operating energy from the Interrogator’s RF signal.
An Interrogator receives information from a Tag by transmitting a continuous-wave (CW) RF signal to
the Tag; the Tag responds by modulating the reflection coefficient of its antenna, thereby backscattering
an information signal to the Interrogator. The system is ITF, meaning that a Tag modulates its antenna
reflection coefficient with an information signal only after being directed to do so by an Interrogator.
Interrogators and Tags are not required to talk simultaneously; rather, communications are half-duplex,
i.e. Interrogators talk and Tags listen, or vice versa.
The described backscatter radio frequency identification (RFID) system that supports the following
system capabilities:
— identification and communication with multiple tags in the field;
— selection of a subgroup of tags for identification or with which to communicate;
— reading from and writing to or rewriting data many times to individual tags;
— user-controlled permanently lockable memory;
— data integrity protection;
— Interrogator-to-tag communications link with error detection;
— tag-to-Interrogator communications link with error detection;
— support for both passive back-scatter tags with or without batteries.
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.
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/she is willing to negotiate licences 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

Introduction
This document defines the physical and logical requirements for a passive-backscatter, Interrogator-
talks-first (ITF), radio-frequency identification (RFID) system operating in the 860 MHz to 960 MHz
frequency range. The system comprises Interrogators, also known as Readers, and Tags, also known as
Labels or Transponders.
An Interrogator transmits information to a Tag by modulating an RF signal in the 860 MHz to 960 MHz
frequency range. The Tag receives both information and operating energy from this RF signal. Tags are
passive, meaning that they receive all of their operating energy from the Interrogator’s RF signal.
An Interrogator receives information from a Tag by transmitting a continuous-wave (CW) RF signal to
the Tag; the Tag responds by modulating the reflection coefficient of its antenna, thereby backscattering
an information signal to the Interrogator. The system is ITF, meaning that a Tag modulates its antenna
reflection coefficient with an information signal only after being directed to do so by an Interrogator.
Interrogators and Tags are not required to talk simultaneously; rather, communications are half-duplex,
i.e. Interrogators talk and Tags listen, or vice versa.
The described backscatter radio frequency identification (RFID) system that supports the following
system capabilities:
— identification and communication with multiple tags in the field;
— selection of a subgroup of tags for identification or with which to communicate;
— reading from and writing to or rewriting data many times to individual tags;
— user-controlled permanently lockable memory;
— data integrity protection;
— Interrogator-to-tag communications link with error detection;
— tag-to-Interrogator communications link with error detection;
— support for both passive back-scatter tags with or without batteries.
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

FINAL DRAFT INTERNATIONAL STANDARD ISO/IEC FDIS 18000-63:2021(E)
Information technology — Radio frequency identification
for item management —
Part 63:
Parameters for air interface communications at 860 MHz
to 960 MHz Type C
1 Scope
This document defines the air interface for radio frequency identification (RFID) devices operating
in the 860 MHz to 960 MHz industrial, scientific, and medical (ISM) band used in item management
applications. It provides a common technical specification for RFID devices that can be used to develop
RFID application standards. This document is intended to allow for compatibility and to encourage
inter-operability of products for the growing RFID market in the international marketplace.
It defines the forward and return link parameters for technical attributes including, but not limited
to, operating frequency, operating channel accuracy, occupied channel bandwidth, maximum effective
isotropic radiated power (EIRP), spurious emissions, modulation, duty cycle, data coding, bit rate, bit
rate accuracy, bit transmission order, and, where appropriate, operating channels, frequency hop rate,
hop sequence, spreading sequence, and chip rate. It further defines the communications protocol used
in the air interface.
This document specifies the physical and logical requirements for a passive-backscatter, Interrogator-
Talks-First (ITF) systems. The system comprises Interrogators, also known as readers, and tags, also
known as labels. An Interrogator receives information from a tag by transmitting a continuous-wave
(CW) RF signal to the tag; the tag responds by modulating the reflection coefficient of its antenna,
thereby backscattering an information signal to the Interrogator. The system is ITF, i.e. a tag modulates
its antenna reflection coefficient with an information signal only after being directed to do so by an
Interrogator.
This document specifies
— physical interactions (the signalling layer of the communication link) between Interrogators and
tags;
— logical operating procedures and commands between Interrogators and Tags;
— the collision arbitration scheme used to identify a specific tag in a multiple-tag environment;
— optional security commands that allow the use of crypto suites of ISO/IEC 29167.
