15、 and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. 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
16、 with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC
17、 have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the j
18、oint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.

22、interface protocols and an Application Program Interface (API) for Real Time Locating Systems (RTLS). ISO/IEC 24730-5 defines an air interface which utilizes Chirp Spread Spectrum (CSS) at frequencies from 2.4- 2.483 GHz. Chirp pulses, which are pulses with a fast increasing or decreasing instantane
23、ous frequency, have originally used for radar applications. Lately, chirp pulses have been also used for communication applications. ISO/IEC 24730-5 includes ranging and bidirectional communication between tags and infrastructures. Bidirectional communication enables the infrastructure to control th
24、e behaviour of tags. The purpose of ISO/IEC TR 24769-5 is to provide tests conditions and methods for conformance to ISO/IEC 24730-5. ISO/IEC TR 24769-5 contains all measurements required to be made on a product in order to establish whether it conforms to ISO/IEC 24730-5. BS ISO/IEC 24769-5:2012BS

28、red to perform the locating of the RTLS tag. It includes the mandatory 2-ary orthogonal chirp spread spectrum (CSS) modulation and the optional differential quadrature phase shift keying (DQPSK) CSS. This part of ISO/IEC 24769 also includes the ranging packet exchanges, the commands and the reports
29、defined in ISO/IEC 24730-5. Unless otherwise specified, the tests in this part of ISO/IEC 24769 shall be applied exclusively to RTLS tags and readers defined in ISO/IEC 24730-5. 2 Normative references The following referenced documents are indispensable for the application of this document.
