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.
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 joint 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 24730-61 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 31, Automatic identification and data capture techniques.
ISO/IEC 24730 consists of the following parts, under the general title Information technology — Real time
locating systems (RTLS):
Part 1: Application program interface (API)
Part 2: Direct Sequence Spread Spectrum (DSSS) 2,4 GHz air interface protocol
Part 5: Chirp spread spectrum (CSS) at 2,4 GHz air interface
Part 21: Direct Sequence Spread Spectrum (DSSS) 2,4 GHz air interface protocol: Transmitters operating
with a single spread code and employing a DBPSK data encoding and BPSK spreading scheme
Part 22: Direct Sequence Spread Spectrum (DSSS) 2,4 GHz air interface protocol: Transmitters operating
with multiple spread codes and employing a QPSK data encoding and Walsh offset QPSK (WOQPSK)
spreading scheme

Introduction
This series of standards defines an air interface protocol for Real Time Locating Systems (RTLS) for use in
asset management and is intended to allow for compatibility and to encourage interoperability of products for
the growing RTLS market.
This document establishes an air interface technical standard for Real Time Locating Systems that operates
within the 6 – 10.6 GHz unlicensed band. RTLSs are wireless systems with the ability to locate the position of
an item anywhere in a defined space (local/campus, wide area/regional, global) at a point in time that is, or is
close to, real time. Position is derived by measurements of the physical properties of the radio link.
Conceptually there are four classifications of RTLS:
– Locating an asset via satellite - requires line-of-sight - accuracy to 10 meters
– Locating an asset in a controlled area, e.g., warehouse, campus, airport - area of interest is
instrumented - accuracy to 3 meters
– Locating an asset in a more confined area - area of interest is instrumented - accuracy to tens of
centimetres
– Locating an asset over a terrestrial area using a terrestrial mounted readers over a wide area, cell
phone towers for example – accuracy 200 meters
With a further two methods of locating an object which are really Radio Frequency Identification (RFID) rather
than RTLS:
– Locating an asset by virtue of the fact that the asset has passed point A at a certain time and has not
passed point B
– Locating an asset by virtue of providing a homing signal whereby a person with a handheld can find
an asset
Method of location is through identification and location, generally through multilateration types
– Time of Flight Ranging Systems
– Amplitude Triangulation
– Time Difference of Arrival (TDOA)
– Cellular Triangulation
– Satellite Multilateration
– Angle of Arrival
This standard defines the air interface protocol needed for the creation of an RTLS system. There are many
types of location algorithms that could be used. Examples of location algorithms are given in Annex A.
