Abstract: This amendment defines modifications to both the IEEE 802.11 physical layer (PHY) and
the IEEE 802.11 medium access control (MAC) sublayer so that modes of operation can be enabled
that are capable of much higher throughputs, with a maximum throughput of at least 100 Mb/s, as
measured at the MAC data service access point (SAP).
Keywords: high throughput, MAC, medium access control, MIMO, MIMO-OFDM, “multiple input,
multiple output,” PHY, physical layer, radio, wireless local area network, WLAN
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 or the soundness of any judgments 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, or every ten years for stabilization. When a document is more than five
years old and has not been reaffirmed
, or more than ten years old and has not been stabilized, 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 Standard.
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 person utilizing this, and any other IEEE Standards document, should rely upon his or
her 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.
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 formal consideration.
A statement, written or oral, that is not processed in accordance with the IEEE-SA Standards Board Operations Manual
shall not be considered the official position of IEEE or any of its committees and shall not be considered to be, nor be
relied upon as, a formal interpretation of the 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, explanation, or interpretation of the IEEE.
Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affiliation
with IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with
appropriate supporting comments.
Recommendations to change the status of a stabilized standard should include a
rationale as to why a revision or withdrawal is required.
Comments on standards and requests for interpretations should
be submitted to the following address:
Secretary, IEEE-SA Standards Board
445 Hoes Lane
Piscataway, NJ 08854
USA
