CSA ISO/IEC 18000-4:19

CSA Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). For brevity, this Standard will be referred to as \"CSA ISO/IEC 18000-4\" throughout. This Standard supersedes CAN/CSA-ISO/IEC 18000-4:16 (adopted ISO/IEC 18000-4:2015). At the time of publication, ISO/IEC 18000-4:2018 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC. The International Standard, was reviewed by the CSA TCIT under the jurisdiction of the CSA Strategic Steering Committee on Information Technology and deemed acceptable for use in Canada. From time to time, ISO/IEC may publish addenda, corrigenda, etc. The TCIT will review these documents for approval and publication. For a listing, refer to the Current Standards Activities page at standardsactivities.csa.ca. This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It hasbeen published as a National Standard of Canada by CSA Group. Scope This document defines the air interface for radio frequency identification (RFID) devices operating in the 2,45 GHz industrial, scientific, and medical (ISM) band used in item management applications. This document provides a common technical specification for RFID devices that can be used by ISO committees developing 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. This document defines the forward and return link parameters for technical attributes including, but not limited to, operating frequency, operating channel accuracy, occupied channel bandwidth, maximum equivalent isotropically 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. This document further defines the communications protocol used in the air interface. This document contains four modes. Mode 1 is an interrogator talks first with passive tag. Mode 2 is a tag talks first with battery-assisted passive tag. Mode 3 is a globally available, ubiquitous network supporting (but not limited to) the logistics and transportation industry; agnostic to any device, commercial or otherwise, requiring global availability. Mode 4 is a configurable data rate active RFID system. It provides the functions of long range objects identification and environmental sense, and it is intended to realize the low cost device and low power consumption, long range identification, fast and reliable tags access. The detailed technical differences between the modes are shown in the parameter tables.
