IEEE 802.15.2 2003 Edition, June 12, 2003 Recommended Practice for Information technology—Telecommunications and information exchange between systems—Local and metropolitan area networks—Specific requirements Part 15.2: Coexistence of Wireless Personal Area Networks with Other Wireless Devices Operating in Unlicensed Frequency Bands

Description / Abstract:
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 IEEE Std 802.11™, 1999
Edition devices to facilitate coexistence with IEEE 802.15 devices
operating in unlicensed frequency bands.
The scope of this recommended practice 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 802.11b-1999 direct sequence spread spectrum standard at data rates of 1, 2, 5.5, and 11 Mbit/s. Both IEEE 802.11™ and IEEE 802.15 are continuing to work on additional standards.
Purpose
Usage models exist that presume coexistence of IEEE 802.15 devices with other wireless devices operating in unlicensed frequency bands. The purpose of this recommended practice is to facilitate coexistence of IEEE 802.15 WPAN devices with selected other wireless devices 2 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 IEEE 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 coexistence 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 mechanism can be used when there is a communication link between the WLAN and WPAN networks. This is best implemented when both a WLAN and WPAN device are embedded into 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 noncollaborative coexistence mechanism does not require any communication link between the WLAN and WPAN.
2 The term "selected wireless devices" includes the following: a) Other 802 devices, and b) other wireless devices in the international marketplace operating in the same frequency band as an IEEE 802.15 WPAN. We will limit our scope to dealing with devices that have 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.
