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
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
Details of any patent rights identified during the development of the document will be in the Introduction
and/or on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/IEC JTC 1, Information technology, SC 6,
Telecommunications and information exchange between systems.
This second edition cancels and replaces the first edition (ISO/IEC 29157:2010), which has been
technically revised.

Introduction
This International Standard is the revision of ISO/IEC 29157. This International Standard was established
to provide a unified platform for services of data rates up to 1 Mbps: control data, voice, audio, and
video. The purpose of the revision is to accommodate the advancement of technology for higher-quality
services in the mobile applications.
The direction of the revision is three-fold: to enhance throughput, to facilitate co-existence with other
technologies such as time-division LTE (long term evolution) and WiMAX II, and to increase data rate.
For the higher throughput, the length of the preamble of the payload frames is made variable up to the
user’s need (see 9.2.2). For the co-existence, the duration of the middle frames is reduced to 4 ms from
16 ms to make align with those of the other technologies (see 8.3). With the shorter middleframes, the
International Standard does not only harmonise with other technologies, but also attains advantages of
shorter communication delay and less paring time. To increase the data rate, the message part of the payload
frames may be modulated with QPSK. The modulation format is indicated by the ‘PHY version’ of the header
(see Clause 7 and 9.3). With the addition of the new option, the data rate can be increased to 2 Mbps. In
addition, to protect communications against security challenges due to the loss of protection provided by
wires, this International Standard provides the optional security mechanism (See 9.3.2 and Annex A).
