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.
IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating
Committees of the IEEE Standards Association (IEEE‐SA) Standards Board. The IEEE develops its standards
through a consensus development process, approved by the American National Standards Institute, which
brings together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers
are not necessarily members of the Institute and serve without compensation. While the IEEE administers the
process and establishes rules to promote fairness in the consensus development process, the IEEE does not
independently evaluate, test, or verify the accuracy of any of the information contained in its standards.
The main task of ISO/IEC JTC 1 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 called to the possibility that implementation of this standard may require the use of
subject matter covered by patent rights. By publication of this standard, no position is taken with
respect to the existence or validity of any patent rights in connection therewith. ISO/IEEE is not responsible
for identifying essential patents or patent claims for which a license may be required, for conducting
inquiries into the legal validity or scope of patents or patent claims or determining whether any
licensing terms or conditions provided in connection with submission of a Letter of Assurance or a
Patent Statement and Licensing Declaration Form, if any, or in any licensing agreements are reasonable
or non‐discriminatory. Users of this standard are expressly advised that determination of the validity
of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility.
Further information may be obtained from ISO or the IEEE Standards Association.
ISO/IEC/IEEE 8802‐15‐4 was prepared by the LAN/MAN of the IEEE Computer Society (as
IEEE 802.15.4‐2015). It was adopted by Joint Technical Committee ISO/IEC JTC 1, Information
technology, Subcommittee SC 6, Telecommunications and information exchange between systems, in
parallel with its approval by the ISO/IEC national bodies, under the “fast‐track procedure” defined in the
Partner Standards Development Organization cooperation agreement between ISO and IEEE. IEEE is
responsible for the maintenance of this document with participation and input from ISO/IEC national bodies.
This second edition cancels and replaces the first edition (ISO/IEC/IEEE 8802-15-4:2010), which has been
technically revised.

Important Notices and Disclaimers Concerning IEEE Standards
Documents
IEEE documents are made available for use subject to important notices and legal disclaimers. These notices
and disclaimers, or a reference to this page, appear in all standards and may be found under the heading
“Important Notice” or “Important Notices and Disclaimers Concerning IEEE Standards Documents.”
Notice and Disclaimer of Liability Concerning the Use of IEEE Standards Docu-
ments
IEEE Standards documents (standards, recommended practices, and guides), both full-use and trial-use, are
developed within IEEE Societies and the Standards Coordinating Committees of the IEEE Standards
Association (“IEEE-SA”) Standards Board. IEEE (“the Institute”) develops its standards through a
consensus development process, approved by the American National Standards Institute (“ANSI”), which
brings together volunteers representing varied viewpoints and interests to achieve the final product.
Volunteers are not necessarily members of the Institute and participate without compensation from IEEE.
While IEEE administers the process and establishes rules to promote fairness in the consensus development
process, IEEE does not independently evaluate, test, or verify the accuracy of any of the information or the
soundness of any judgments contained in its standards.
IEEE does not warrant or represent the accuracy or content of the material contained in its standards, and
expressly disclaims all warranties (express, implied and statutory) not included in this or any other
document relating to the standard, including, but not limited to, the warranties of: merchantability; fitness
for a particular purpose; non-infringement; and quality, accuracy, effectiveness, currency, or completeness
of material. In addition, IEEE disclaims any and all conditions relating to: results; and workmanlike effort.
IEEE standards documents are supplied “AS IS” and “WITH ALL FAULTS.”
Use of an IEEE standard is wholly voluntary. The existence of an IEEE standard does not imply that there
are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to
the scope of the IEEE standard. Furthermore, the viewpoint expressed at the time a standard is approved and
issued is subject to change brought about through developments in the state of the art and comments
received from users of the standard.
In publishing and making its standards available, IEEE is not suggesting or rendering professional or other
services for, or on behalf of, any person or entity nor is IEEE undertaking to perform any duty owed by any
other person or entity to another. Any person utilizing any IEEE Standards document, should rely upon his
or her own independent judgment in the exercise of reasonable care in any given circumstances or, as
appropriate, seek the advice of a competent professional in determining the appropriateness of a given IEEE
standard.
IN NO EVENT SHALL IEEE BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,
EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO:
PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA, OR PROFITS; OR
BUSINESS INTERRUPTION) HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY,
WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR
OTHERWISE) ARISING IN ANY WAY OUT OF THE PUBLICATION, USE OF, OR RELIANCE
UPON ANY STANDARD, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE AND
REGARDLESS OF WHETHER SUCH DAMAGE WAS FORESEEABLE.
Translations
The IEEE consensus development process involves the review of documents in English only. In the event
that an IEEE standard is translated, only the English version published by IEEE should be considered the
approved IEEE standard.
Official statements
A statement, written or oral, that is not processed in accordance with the IEEE-SA Standards Board
Operations Manual shall not be considered or inferred to be the official position of IEEE or any of its
committees and shall not be considered to be, or be relied upon as, a formal position of IEEE. At lectures,
symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall
make it clear that his or her views should be considered the personal views of that individual rather than the
formal position of IEEE.
Comments on standards
Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of
membership affiliation with IEEE. However, IEEE does not provide consulting information or advice
pertaining to IEEE Standards documents. Suggestions for changes in documents should be in the form of a
proposed change of text, together with appropriate supporting comments. Since IEEE standards represent a
consensus of concerned interests, it is important that any responses to comments and questions also receive
the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and
Standards Coordinating Committees are not able to provide an instant response to comments or questions
except in those cases where the matter has previously been addressed. For the same reason, IEEE does not
respond to interpretation requests. Any person who would like to participate in revisions to an IEEE
standard is welcome to join the relevant IEEE working group.
Comments on standards should be submitted to the following address:

Laws and regulations
Users of IEEE Standards documents should consult all applicable laws and regulations. Compliance with the
provisions of any IEEE Standards document does not imply compliance to any applicable regulatory
requirements. Implementers of the standard are responsible for observing or referring to the applicable
regulatory requirements. IEEE does not, by the publication of its standards, intend to urge action that is not
in compliance with applicable laws, and these documents may not be construed as doing so.
Copyrights
IEEE draft and approved standards are copyrighted by IEEE under U.S. and international copyright laws.
They are made available by IEEE and are adopted for a wide variety of both public and private uses. These
include both use, by reference, in laws and regulations, and use in private self-regulation, standardization,
and the promotion of engineering practices and methods. By making these documents available for use and
adoption by public authorities and private users, IEEE does not waive any rights in copyright to the
documents.
