IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Stan-
dards 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.
Use of an IEEE Standard is wholly voluntary. The IEEE disclaims liability for any personal injury, property or other damage, of any
nature whatsoever, whether special, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use
of, or reliance upon this, or any other IEEE Standard document.
The IEEE does not warrant or represent the accuracy or content of the material contained herein, and expressly disclaims any express or
implied warranty, including any implied warranty of merchantability or fitness for a specific purpose, or that the use of the material
contained herein is free from patent infringement. IEEE Standards documents are supplied “AS IS.”
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. Every IEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a document is
more than five years old and has not been reaffirmed, it is reasonable to conclude that its contents, although still of some value, do not
wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Stan-
dard.
In publishing and making this document available, the IEEE is not suggesting or rendering professional or other services for, or on
behalf of, any person or entity. Nor is the IEEE undertaking to perform any duty owed by any other person or entity to another. Any per-
son utilizing this, and any other IEEE Standards document, should rely upon the advice of a competent professional in determining the
exercise of reasonable care in any given circumstances.
Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specific applications.
When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses.
Since IEEE Standards represent a consensus of concerned interests, it is important to ensure that any interpretation has also received 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 interpretation requests except in those cases where the matter has previously received for-
mal consideration.
Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affiliation with IEEE. Sug-
gestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments.
Comments on standards and requests for interpretations should be addressed to:

Note: Attention is called to the possibility that implementation of this standard may require 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. The IEEE shall not be responsible for identifying patents for which a license may be
required by an IEEE standard or for conducting inquiries into the legal validity or scope of those patents that are brought
to its attention. A patent holder has filed a statement of assurance that it will grant licenses under these rights without com-
pensation or under reasonable rates and nondiscriminatory, reasonable terms and conditions to all applicants desiring to
obtain such licenses. The IEEE makes no representation as to the reasonableness of rates and/or terms and conditions of
the license agreements offered by patent holders. Further information may be obtained from the IEEE Standards
Department.

Introduction
This amendment is part of a family of standards for local and metropolitan area networks. The relationship
between the standard and other members of the family is shown below. (The numbers in the figure refer to
IEEE standard designations.
1
)
This family of standards deals with the Physical and Data Link layers as defined by the International
Organization for Standardization (ISO) Open Systems Interconnection (OSI) Basic Reference Model (ISO/
IEC 7498-1: 1994). The access standards define five types of medium access technologies and associated
physical media, each appropriate for particular applications or system objectives. Some access standards
have been withdrawn and other types are under investigation.
The standards defining the technologies noted above are as follows:
• IEEE Std 802:
2
Overview and Architecture. This standard provides an overview to the family of
IEEE 802 Standards.
• IEEE Std 802.1B
™
LAN/MAN Management. Defines an OSI management-compatible architecture
and 802.1k
™
and services and protocol elements for use in a LAN/MAN environment for
[ISO/IEC 15802-2] performing remote management.
• IEEE Std 802.1D
™
Media Access Control (MAC) Bridges. Specifies an architecture and protocol
for the interconnection of IEEE 802 LANs below the MAC service boundary.

The IEEE 802 Overview and Architecture Specification, originally known as IEEE Std 802.1A, has been renumbered as IEEE Std 802.
This has been done to accommodate recognition of the base standard in a family of standards. References to IEEE Std 802.1A should be
considered as references to IEEE Std 802.
This introduction is not part of IEEE Std 802.11g-2003 (Amendment to IEEE Std 802.11, 1999 Edition,
as amended by IEEE Stds 802.11a-1999, 802.11b-1999, 802.11b-1999/Cor 1-2001, and 802.11d-2001),
