Background 802.15 has TG2 coexistence group March 2002 Background 802.15 has TG2 coexistence group 802.11b and Bluetooth(TG1) coexistence BWA in unlicensed bands uses same spectrum as WLAN 802.16 has an internal coexistence TG Jim Lansford, Mobilian Corporation

Today’s Presentations March 2002 Today’s Presentations The meaning of “Coexistence” Coexistence vs. Interoperability Simultaneous transmission: Another coexistence issue Jim Lansford, Mobilian Corporation

March 2002 What is a TAG? Rules: Jim Lansford, Mobilian Corporation

March 2002 Statement of Purpose Goal is to have a group that can review and make coexistence recommendations to ExCom on current or proposed PARs within the established wireless WGs of the IEEE802 standards body Similar in concept to the FCC OET, which makes recommendations to the commissioners about policy The functional charter of this new group is to address the wireless coexistence issues across all wireless WGs Jim Lansford, Mobilian Corporation

Impact to Existing Efforts March 2002 Impact to Existing Efforts The activities of 802.15.2 remain unchanged. They can continue working on their specific tasks at hand. No impact on 802.11h DFS is a coexistence mechanism The 802.16.2 Coexistence activity for Licensed bands remains unchanged. Jim Lansford, Mobilian Corporation

Possible 802 COEX TAG Structure March 2002 Possible 802 COEX TAG Structure Membership by WG rules Credit for own WG attendance, if WG chair allows Jim Lansford, Mobilian Corporation

802 COEX TAG Procedures Membership & Voting Ratification of guidelines March 2002 802 COEX TAG Procedures Membership & Voting Attendance at the 802 COEX Tag meetings is open to anyone Attendance at first meeting grants membership TAG follows WG rules after that Attendance at 802 COEX TAG meetings will count towards attendance at the individual’s primary WG WG chairs would have to agree to this Ratification of guidelines A guideline requires a 75% approval vote by the members of the 802 COEX TAG as outlined above The guideline is then presented to ExCom and the appropriate wireless WG(s) Minority opinion summary would be included Jim Lansford, Mobilian Corporation

Regulatory & Coexistence Complementary Charters March 2002 Regulatory & Coexistence Complementary Charters Regulatory TAG Harmonize the IEEE 802 activities with the worldwide regulatory bodies Coexistence TAG Harmonize the IEEE 802 activities with the internal wireless WGs relative to unlicensed bands Jim Lansford, Mobilian Corporation

March 2002 Summary Next steps Finalize TAG proposal based on feedback from this meeting Make motion to create TAG at SEC meeting on Friday Jim Lansford, Mobilian Corporation
