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 Canadian Advisory Committee (CAC) 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 \"CAN/CSA-ISO/IEC 24791-1\" throughout. At the time of publication, ISO/IEC 24791-1:14 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC. This Standard has been formally approved, without modification, by the Technical Committee and has been approved as a National Standard of Canada by the Standards Council of Canada. Scope ISO/IEC 24791 defines a Software System Infrastructure that enables RFID system operations between business applications and RFID interrogators. RFID software systems are composed of RFID interrogators, intermediate software systems, and applications that provide control and coordination of air interface operation, tag and sensor information exchange, and health and performance management of system components. This part of ISO/IEC 24791 provides the following: - an overview of the Software System Infrastructure; - the relationship of the Software System Infrastructure to existing ISO components, e.g. ISO/IEC 15962; - a basic description of each Software System Infrastructure component and the services that it provides (The detailed description of a particular component can be found in other Parts of ISO/IEC 24791.); - illustrative (informative) deployment models of the components of the Software System Infrastructure.
