23、Ultra Wide Band (UWB) air interface 1 Scope This International Standard defines the test methods for determining the conformance of Ultra Wide Band real-time locating system (RTLS) tags with the specifications given in the corresponding parts of ISO/IEC 24730-62, but does not apply to the testing of

24、 conformity with regulatory or similar requirements. The test methods require only that the mandatory functions, and any optional functions which are implemented, be verified. This may in appropriate circumstances, be supplemented by further, application specific functionality criteria that are not

25、available to the general case. Unless otherwise specified, the tests in this International Standard apply exclusively to RTLS tags defined in ISO/IEC 24730-62. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for i
