Information technology — Automatic identification and data capture techniques — Real time locating systems (RTLS) device conformance test methods — Part 5: Test methods for chirp spread spectrum (CSS) at 2,4 GHz air interface
ISO/IEC 24769-5:2012 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. ISO/IEC 24769-5:2012 does not include the testing of conformity with regulatory requirements. The test methods require only that the mandatory functions, and any optional functions which are implemented, be verified. The conformance parameters described in ISO/IEC 24769-5:2012 include the radio frequency air interface and packet exchange required 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. ISO/IEC 24769-5:2012 also includes the ranging packet exchanges, the commands and the reports defined in ISO/IEC 24730-5. Unless otherwise specified, the tests in ISO/IEC 24769-5:2012 shall be applied exclusively to RTLS tags and readers defined in ISO/IEC 24730-5.
