doc.: IEEE /010r0 Submission January 2000 Steve Shellhammer, Symbol TechnologiesSlide 2 Our plan for the week Report on ExCom vote in Kauai Start development of Coexistence Model Call for Submissions on Coexistence Mechanisms Discuss with Jim Lansford on how TG2 and Bluetooth SIG can work together Presentations on Coexistence Model and Coexistence Mechanisms

doc.: IEEE /010r0 Submission January 2000 Steve Shellhammer, Symbol TechnologiesSlide 3 Develop a Coexistence Model for the 2.4 GHz ISM band, that we can all agree to, which will help us assess the issues of Coexistence in a more quantitative way Deliver a Recommended Practice for WPAN devices intended to operate in a WLAN environment. Coexistence Task Group Charter

In order for the Recommended Practice to be forwarded to the Executive Committee for Sponsor ballot, the letter ballot must pass in both Working Groups. Agreement between &

doc.: IEEE /010r0 Submission January 2000 Steve Shellhammer, Symbol TechnologiesSlide 10 Call for submission on Coexistence Mechanisms As members of the Task Group are developing the Coexistence Model they may think of ideas on how to facilitate coexistence of WPAN and WLAN devices. The purpose of this Call for Submissions is to solicit submissions on these Coexistence Mechanisms to IEEE Coexistence Task Group, IEEE /009r0

doc.: IEEE /010r0 Submission January 2000 Steve Shellhammer, Symbol TechnologiesSlide 11 Discussion on TG2 and Bluetooth Collaboration Met with Jim Lasford and Evan Green from Intel, representing the Bluetooth SIG Bluetooth recently established a Task Group on WLAN interference. The goals of that task group are consistent with the goals of TG2. Going forward we will look for ways to work together.
