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 and recommendations on standards, and requests for interpretations should be
addressed to:

Introduction
This introduction is not part of IEEE Std 802.11p-2010, IEEE Standard for Information technology—
Telecommunications and information exchange between systems—Local and metropolitan networks—Specific
requirements—Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications—
Amendment 6: Wireless Access in Vehicular Environments.
IEEE 802.11™ devices may be used in environments where the physical layer properties are rapidly
changing and where very short-duration communications exchanges are required. The purpose of this
standard is to provide the minimum set of specifications required to ensure interoperability between wireless
devices attempting to communicate in potentially rapidly changing communications environments and in
situations where transactions must be completed in time frames much shorter than the minimum possible
with infrastructure or ad hoc IEEE 802.11 networks. In particular, time frames that are shorter than the
amount of time required to perform standard authentication and association to join a BSS are accommodated
in this amendment.
This specification accomplishes the following:
— Describes the functions and services required by stations to operate in a rapidly varying environment
and to exchange messages without joining a BSS
— Defines the signaling techniques and interface functions used by stations communicating outside of
the context of a BSS that are controlled by the IEEE 802.11 MAC
This amendment to IEEE Std 802.11-2007 is based on extensive testing and analyses of wireless
communications in a mobile environment. The results of these efforts are documented in ASTM E2213-03,
Standard Specification for Telecommunications and Information Exchange Between Roadside and Vehicle
Systems—5.9 GHz Band Wireless Access in Vehicular Environments (WAVE)/Dedicated Short Range
Communications (DSRC) Medium Access Control (MAC) and Physical Layer (PHY) Specifications.a This
amendment to IEEE Std 802.11-2007 is technically compatible with ASTM E2213-03.

Updating of IEEE documents
Users of IEEE standards should be aware that these documents may be superseded at any time by the
issuance of new editions or may be amended from time to time through the issuance of amendments,
corrigenda, or errata. An official IEEE document at any point in time consists of the current edition of the
document together with any amendments, corrigenda, or errata then in effect. In order to determine whether
a given document is the current edition and whether it has been amended through the issuance
of amendments, corrigenda, or errata, visit
the IEEE Standards Association website at http://
ieeexplore.ieee.org/xpl/standards.jsp, or contact the IEEE at the address listed previously.

Patents
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. A patent holder or patent applicant has filed a statement
of assurance that it will grant licenses under these rights without compensation or under reasonable rates,
with reasonable terms and conditions that are demonstrably free of any unfair discrimination to applicants
desiring to obtain such licenses. Other Essential Patent Claims may exist for which a statement of assurance
has not been received. The IEEE is not responsible for identifying Essential Patent Claims for which a
license may be required, for conducting inquiries into the legal validity or scope of Patents Claims, or
determining whether any licensing terms or conditions provided in connection with submission of a Letter of
Assurance, 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
the IEEE Standards Association.
