`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(cid:173)
`itan area networks. The medium access control unit in this standard is designed to support physical
`layer units as they may be adopted dependent on the availability of spectrum. This standard con(cid:173)
`tains three physical layer units: two radio units, both operating in the 2400-2500 MHz band, and
`one baseband infrared unit. One radio unit employs the frequency-hopping spread spectrum tech(cid:173)
`nique, 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 Committees of the IEEE Standards Board. Members of the com(cid:173)
`mittees serve voluntarily and without compensation. They are not necessarily members of the Insti(cid:173)
`tute. 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 inter(cid:173)
`est in participating in the development of the standard.
`
`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. Every IEEE Standard is sub(cid:173)
`jected 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 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 rep(cid:173)
`resent 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 provide 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:

`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.

`"Formerly IEEE Std 802.1A.
`
`This family of standards deals with the physical and data link layers as defined by the International Organi(cid:173)
`zation for Standardization/International Electrotechnical Commission (ISOIIEC) Open Systems Intercon(cid:173)
`nection Basic Reference Model (ISO/IEC 7498-1: 1994 ). The access standards define several types of
`medium access technologies and associated physical media, each appropriate for particular applications or
`system objectives. Other types are under investigation.
`
`The standards defining the access technologies are as follows:
`
`• IEEE Std 802
`
`Overview and Architecture. This standard provides an overview to the fam(cid:173)
`ily of IEEE 802 Standards. This document forms part of the 802.1 scope of
`work.

`management-compatible architecture, and services and protocol elements
`for use in a LAN/MAN environment for performing remote management.

`[ISOIIEC 10038]
`
`MAC Bridging. Specifies an architecture and protocol for the interconnec(cid:173)
`tion of IEEE 802 LANs below the MAC service boundary.
`
`• ANSI/IEEE Std 802.1E
`[ISOIIEC 15802-4]
`
`System Load Protocol. Specifies a set of services and protocol for those
`aspects of management concerned with the loading of systems on IEEE
`802LANs.

`
`In addition to the family of standards, the following is a recommended practice for a common Physical
`Layer technology:
`
`• IEEE Std 802.7
`
`IEEE Recommended Practice for Broadband Local Area Networks
`
`The following additional working group has authorized standards projects under development:
`
`• IEEE 802.14
`
`Standard Protocol for Cable-TV Based Broadband Communication Network
`
`The reader of this standard is urged to become familiar with the complete family of standards.
`
`Conformance test methodology
`
`An additional standards series, identified by the number 1802, has been established to identify the
`conformance test methodology documents for the 802 family of standards. Thus the conformance test
`documents for 802.3 are numbered 1802.3.
`
`IEEE Std 802.11-1997
`
`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(cid:173)
`bounded transfer of data. The standard includes the definition of the management information base (Mill)
`using Abstract Syntax Notation 1 (ASN.l) and specifies the MAC protocol in a formal way, using the Speci(cid:173)
`fication and Description Language (SDL).
`
`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) support(cid:173)
`ing 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
`possible errors, and to incorporate new related material. Information on the current revision state of this and
`other IEEE 802 standards may be obtained from
