Foreword
ISO (the International Organization for Standardization) 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 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 have established a joint technical committee,
ISO/IEC JTC 1.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject

Introduction
ISO/IEC 24730-62 defines an air interface for Real Time Locating Systems (RTLS) devices used in asset
management applications.
This International Standard provides test methods for measuring performance of equipment compliant
with ISO/IEC 24730-62.
ISO/IEC IS 24769-62 contains all measurements required to be made on a product in order to establish
whether it conforms to ISO/IEC 24730-62.

Information technology — Real-time locating system
(RTLS) device performance test methods —
Part 62:
High rate pulse repetition frequency Ultra Wide Band
(UWB) air interface
1 Scope
This International Standard defines the test methods for determining the performance characteristics
of Ultra Wide Band (UWB) real time locating system (RTLS) equipment including tags and readers
which are applicable to the selection of equipment that conforms to ISO/IEC 24730-62 for specific
applications. This International Standard does not apply to the testing in relation to regulatory or
similar requirements.
The RTLS equipment performance parameters included in this International Standard only include the
Ultra Wide Band (UWB) radio frequencies link between tags and readers. Unless otherwise specified, the
tests in this International Standard apply exclusively to RTLS equipment defined in ISO/IEC 24730-62.

4.1 Performance requirements
4.1.1 Preface
This part of ISO/IEC 24770 specifies a series of tests to determine the performance characteristics of
RTLS equipment relative to the ISO/IEC 24730-62 air interfaces. The results of these tests can be used
to determine the suitability of RTLS equipment for applications.
4.1.2 Location accuracy
The primary function of RTLS equipment is to locate tags within the area covered by the readers.
Location accuracy determines the primary performance criteria of an RTLS. Location accuracy can be
characterized by comparing the system’s calculated location for a given set of tags to the actual location
of the tags. The system must be able to locate tags to within the applications allowable error. The
location tests specified in this standard are confined to line-of-sight situations. Although this will not
be applicable to all applications, the complexity of all the variations of blockage and partial blockage
are beyond the scope of this test.
4.1.3 Tag capacity
A RTLS must typically locate a large number of tags. The number of tag blinks per second that can
be processed and located through the readers can be used to determine a system’s tag capacity. The
system must be able to provi
