`
`Abstract: This recommended practice addresses the issue of coexistence of wireless local area
`networks and wireless personal area networks. These wireless networks often operate in the
`same unlicensed band. This recommendedpractice describes coexistence mechanismsthat can
`be used to facilitate coexistence of wireless local area networks ({i.e.,
`IEEE Std 802.11b™-
`1999)and wireless personal area networks(i.e., IEEE Std 802.15.1 ™-2002).

`
`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 containedinits standards.
`
`Use of an TEEEStandard is wholly voluntary. The IEEEdisclaimsliability 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 hereinis free from patent infringement. IEEE Standards documentsare 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 TEEE Standard. Furthermore, the viewpoint expressed at the time a standard is
`approved and issued is subject to change brought about through developmentsin 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 documentis
`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
`whollyreflect 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 documentavailable, the IEEE is not suggesting or rendering professional or other services for, or on
`behalf of, any personor entity. Nor is the TEEE undertaking to perform any duty owed by any other personor 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 broughtto the attention of IEEE, the Institute will initiate action to prepare appropriate responses.
`Since IEEE Standards represent a consensus of concernedinterests, it is important to ensure that any interpretation has also received the
`concurrence of a balance ofinterests. For this reason, IEEE and the membersof 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 welcomefrom any interested party, regardless of membership affiliation with IEEE. Sug-
`gestions for changes in documents should be in the form of a proposed change oftext, together with appropriate supporting comments.
`Comments on standards and requests for interpretations should be addressedto:

`
`Note: Attention is called to the possibility that implementation of this standard may require use of subject matter covered
`by patent rights. By publicationof this standard, no position is taken with respect to the existence or validity of any patent
`rights in connection therewith. The TREF. 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 assurancethat 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.

`Specific requirements
`
`Part 15.2: Coexistence of Wireless Personal
`Area Networks with Other Wireless Devices
`Operating in Unlicensed Frequency Bands
`
`1. Overview
`
`This recommendedpractice addresses the issue of coexistence of wireless personal area networks (WPAN)
`and wireless local area networks (WLAN). These wireless networks often operate in the same unlicensed
`frequency band. This recommendedpractice describes coexistence mechanisms that can be used to facilitate
`coexistence of WPANs (i.c., IEEE Std 802.15.1™-2002!) and WLANs(..e., IEEE Std 802.1 1b™-1999).
`The unlicensed frequency bands used by each wireless technology are specified within its respective stan-
`dard. This recommended practice also describes a computer model of the mutual interference between IEEE
`Sid 802.15.1-2002 and IEEE Std 802.1 1b-1999 for information.
`
`1.1 Scope
`
`The scope is to develop a recommended practice for an IEEE 802.15™ WPAN that coexists with other
`selected wireless devices operating in unlicensed frequency bands, to suggest modifications to other IEEE
`802.15 standards to enhance coexistence with other selected wireless devices operating in unlicensed
`frequency bands, and to suggest recommended practices for TEEE Sid 802.11™, 1999 Edition devices to
`facilitate coexistence with TEEE 802.15 devices operating in unlicensed frequency bands.
`
`The scope of this recommendedpractice is limited to coexistence of IEEE Std 802.15.1-2002 WPANs and
`IEEE Std 802.11b-1999 WLANs. This recommended practice will cover the IEEE Std 802.1 16-1999 direct
`sequence spread spectrum standard at data rates of 1, 2, 5.5, and 11 Mbit/s. Both TEEE 802.11™ and IEEE
`802.15 are continuing to work on additional standards.
`
`linformation on references can be found in Clause 2.

`
`LOCAL AND METROPOLITAN AREA NETWORKS—PART 15.2: COEXISTENCE OF WPANS
`
`1.2 Purpose
`
`Usage models exist that presume cocxistence of IEEE 802.15 devices with other wircless devices operating
`in unlicensed frequency bands. The purpose of this recommended practice is to facilitate coexistence of
`IEEE 802.15 WPANdevices with selected other wireless devices” operating in unlicensed frequency bands.
`The intended users of this recommended practice include IEEE 802 WLAN developers, as well as designers
`and consumers of wireless products being developed to operate in unlicensed frequency bands.
`
`This recommended practice includes a computer model of the mutual interference of an TEEE 802.11b
`WLAN and IEEE 802.15.1 WPAN. This model can be used to predict the impact of the mutual interference
`between these wireless systems. The model includes many parameters that can be modified to fit various
`user scenarios.
`
`This recommended practice defines several coexistence mechanisms that can be used to facilitate coexist-
`ence of WLAN and WPAN networks. The several coexistence mechanisms defined in this recommended
`practice are divided into two classes: collaborative and non-collaborative. A collaborative coexistence mech-
`anism can be used whenthere is a communication link between the WLAN and WPAN networks. This is
`best implemented when both a WLAN and WPANdevice are embeddedinto the same piece of equipment
`(e.g., an IEEE 802.11b card and an IEEE 802.15.1 module embedded in the same laptop computer). A non-
`collaborative coexistence mechanism does not require any communication link between the WLAN and
`WPAN.

`usage scenarios that assume IEEE 802.15 devices will coexist with these selected and that we are able to obtain technical specification
`on these selected devices.
