Violators may be prosecuted. 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.
Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. Informative Annexes to this Standard provide contact information in respect of the radio regulations within which such systems have to operate, and some informational views of system architectures within which RFID for item management is likely to be used. Annexes A and C. Vision statement This Standard ISO defines of a common set of parameters that are necessary at any frequency in order to avoid contention or interference with other RFID systems, to establish the highest degree of interoperability as is practicable, and to ease migration between technical solutions and their supporting software.
The Standard envisions common methods of determination and description. Mission statement The mission of this Standard is to determine common parameters to be defined in an item identification air interface Standard; the method and means of their definition, and to provide a common format for their elaboration and definition.
Subsequent Parts of this Standard ISO —2 to ISO —n , shall provide the parameter definitions, at different frequencies, for each of the parameters required by this Standard in accordance with the common format herein determined, and may also, where appropriate, provide regional definitions with geographical constraints.
If any parameter defined in this Standard is inappropriate at a particular frequency, it shall be specifically and expressly stated in that Part of the Standard that the named and referenced parameter is not appropriate at that frequency. This Standard also provides description of example conceptual architectures in which these air interfaces are often to be utilized. See Section 6, fig 1. The means of generating and managing such transactions, other than a requirement to achieve the transactional performance determined within this Standard, are outside the scope of this Standard, as is the definition or specification of any supporting hardware, firmware, software or associated equipments.
See fig 1. Command specification clauses provide a full definition of the command and its presentation. Interrogators shall be technically capable of performing all optional commands that are specified in the Standard although need not be set up to do so. Tags may or may not support optional commands.
If an optional command is used, it shall be implemented in the manner specified in the Standard. A custom command shall not solely duplicate the functionality of any mandatory or optional command defined in the Standard by a different method.
A proprietary command shall not solely duplicate the functionality of any mandatory or optional command defined in the Standard by a different method. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document including any amendments applies.
Amendment 1 Rules of Extensibility. Such systems may or may not be interoperable, but shall not significantly interfere with each other. This Standard limits its Scope to transactions and data exchanges across the air interface at Reference Point Delta. See Figure 6. Standardisation of other Reference Points are outside the scope of this Standard. This block contains all centralised functions of General Distribution Logistic Model applications.
Local System. This is the local roadside Entity that handles the "real-time" and distributed parts of the General Distribution Logistic Model application. Fixed Communication Control. Communication block that handles the medium independent part of the communication link. Media Adaptation. The medium dependent Entity On-board Communication Control. Communication control that handles the medium independent part of the communication link. Application Processes.
This Entity symbolises several in-vehicle applications, of which the General Distribution Logistic Model may be only one application process. Alpha is the reference point which delimits the functions of the central system and the local system.
The reference point where data, commands, etc. Between fixed communication control and media adaptation. Between on-board and fixed equipment. This reference point usually corresponds with an air interface in the nature of Dedicated Short Range Communication. Between media adaptation and on-board communication control.
Reference point between on-board communication control and application processes. Initialisation A1 2. The slave, if prepared to handle any of these, can start the transmission referring to the chosen application.
Some example typical conceptual architecture views and contexts in which RFID for item Management are likely to be used are shown in Annex C.
