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. IS

16、O 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 have established a joint technical committee, IS

22、terface (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 instantaneous frequency, have originally used for radar appl

23、ications. 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 the behaviour of tags. The purpose of ISO/IEC TR 247

24、69-5 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.

26、24769 defines the test methods for determining the conformance of real time locating systems (RTLS) tags and readers with the specifications given in the corresponding parts of ISO/IEC 24730-5. This part of ISO/IEC 24769 does not include the testing of conformity with regulatory requirements. The te

27、st methods require only that the mandatory functions, and any optional functions which are implemented, be verified The conformance parameters described in this part of ISO/IEC 24769 include the radio frequency air interface and packet exchange required to perform the locating of the RTLS tag. It in

28、cludes 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 defined in ISO/IEC 24730-5. Unless otherwise speci

29、fied, 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.
