`Abstract: The medium access control (MAC) and physical characteristics for wireless local area
`networks (LANs) are specified in this standard, part of a series of standards for local and metropol-
`itan area networks.The medium access control unit in this standard is designed to support physi—
`cal layer units as they may be adopted dependent on the availability of spectrum. This standard
`contains three physical layer units: two radio units, both operating in the 2400—2500 MHz band,
`and one baseband infrared unit. One radio unit employes the frequency—hopping spread spectrum
`technique, and the other employs the direct sequence spread spectrum technique.
`Keywords: ad hoc network, infrared, LAN, local area network, mobility, radio frequency, wireless

`
`IEEE Standards documents are developed within the Technical Committees of the IEEE Societies and the
`Standards Coordinating Connnittees of the IEEE Standards Board. Members of the committees serve volun—
`tarily and without compensation. They are not necessarily members of the Institute. The standards developed
`Within IEEE represent a consensus of the broad expertise on the subject within the Institute as well as those
`activities outside of IEEE that have expressed an interest in participating in the development of the standard.
`
`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.
`
`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
`all 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 technical committees are not able to pro-
`vide an instant response to interpretation requests except in those cases where the matter has previously
`received formal consideration.
`
`Comments on standards and requests for interpretations should be addressed to:
`
`Secretary, IEEE Standards Board

`
`Note: Attention is called to the possibility that implementation of this standard may require use of sub—
`ject matter covered by patent rights. By publication ofthis 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 all 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.
`The patent holder has, however, filed a statement of assurance that it will grant a license under these
`rights without compensation or under reasonable rates and nondiscriminatory, reasonable terms and
`conditions to all applicants desiring to obtain such a license. The IEEE makes no representation as to
`the reasonableness of rates and/or terms and conditions of the license agreement offered by the patent
`holder. Contact information may be obtained from the IEEE Standards Department.
`
`
`
`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 fiom 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 reaflirmed, it is rea-
`sonable 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.
`
`
`
`Authorization to photocopy portions of any individual standard for internal or personal use is granted by the
`Institute of Electrical and Electronics Engineers, Inc., provided that the appropriate fee is paid to Copyright
`Clearance Center. To arrange for payment of licensing fee, please contact Copyright Clearance Center, Cus—
`tomer Service, 222 Rosewood Drive, Danvers, MA 01923 USA; (978) 750—8400. Permission to photocopy
`portions of any individual standard for educational classroom use can also be obtained through the Copy—
`right Clearance Center.

`This family 0 "standards deals with the Physical and Data Link layers as defined by the International Organiza—
`tion for Standardization (ISO) Open Systems Interconnection (OSI) Basic Reference Model (ISO/IEC 7498-
`l: 1994). The access standards define seven types of medium access technologies and associated physical
`media, each appropriate forpaiticular applications or system objectives. Other types are under investigation.
`
`The standards defining the access technologies are as follows:

`This standard defines the protocol and compatible interconnection of data communication equipment via the
`“air”, radio or infrared, in a local area network (LAN) using the carrier sense multiple access protocol with
`collision avoidance (CSMA/CA) medium sharing mechanism. The medium access control (MAC) supports
`operation under control of an access point as well as between independent stations. The protocol includes
`authentication, association, and reassociation services, an optional encryption/decryption procedure, power
`management to reduce power consumption in mobile stations, and a point coordination function for time—
`bounded transfer of data. The standard includes the definition of the management information base (MIB)
`using Abstract Syntax Notation 1 (ASN.1) and specifies the MAC protocol in a formal way, using the Speci—

`
`This standard is a revision of IEEE Std 802.11—1997. The Management Information Base according to 0S1
`rules has been removed, many redundant management items have been removed, and Annex D has been
`completed with the Management Information Base according to SNMP. Minor changes have been made
`throughout the document.

`
`The infrared implementation of the PHY supports 1 Mbit/s data rate with an optional 2 Mbit/s extension.
`The radio implementations of the PHY specify either a frequency—hopping spread spectrum (FHSS)
`supporting 1 Mbit/s and an optional 2 Mbit/s data rate or a direct sequence spread spectrum (DSSS)
`supporting both 1 and 2 Mbit/s data rates.
`
`This standard contains state-of—the—art material. The area covered by this standard is undergoing evolution.
`Revisions are anticipated to this standard Within the next few years to clarify existing material, to correct
