Defer decision to continue/discontinue the Inter- working project until after the IEEE meeting in Portland. It was noted that both BRAN and IEEE will be meeting during the same week in September in Seattle and a joint meeting at that time would be desirable and presumably easy to arrange.

CSMA members shall directly participate in 5GSG/IEEE802.11 meetings representing each company for the globalization discussion, if necessary. MMAC-PC will continue to work together with ETSI-BRAN and IEEE802.11 members within joint 5GSG framework for short term harmonization. CASG participants agreed to create a new group to work toward a single standard of the next generation wireless LAN including wireless Homelink applications using 5GHz band. This new group will be a joint group comprising HiSWANa members and Wireless Homelink members of MMAC- PC.

10. doc.: IEEE 802.15-01/371r0 Submission July 2001 Tim Blaney, MobilianSlide 10 Amend something previously adopted This is a motion that can be used if it is desired to change only a part of the text or to substitute a different version. This requires a two-thirds vote RONR (10 th ed.), Section 35, pg 293 ff

11. doc.: IEEE 802.15-01/371r0 Submission July 2001 Tim Blaney, MobilianSlide 11 Rescind A motion by which a previous action or order can be canceled or counter mended. The effect of rescind is to strike out an entire main motion that has been adopted at some previous time This requires a two-thirds vote RONR (10 th ed.), Section 35, pg 293 ff

12. doc.: IEEE 802.15-01/371r0 Submission July 2001 Tim Blaney, MobilianSlide 12 Reconsider Reconsider – enables a majority in an assembly to bring back for further consideration a motion which has already been voted on. The purpose of reconsidering a vote is to permit correction of hasty, ill-advised or erroneous action, or to take into account added information or a changed situation that has developed since the taking of the vote –It can only be made by a member on the prevailing side during the session at which the original motion was approved. This requires a two-thirds vote RONR (10 th ed.), Section 37, pg 304 ff

13. doc.: IEEE 802.15-01/371r0 Submission July 2001 Tim Blaney, MobilianSlide 13 Scope of Proposed Project: Establish coexistence and inter-working among the 802.11a, ETSI HiperLAN/2, MMAC CSMA and HiSWANa standards. Extension of each of the MAC and PHY layers of these standards will be defined collaboratively to achieve coexistence and inter-working. Purpose of Proposed Project: To establish coexistence and inter-working among the 802.11a, ETSI HiperLAN/2, MMAC CSMA and HiSWANa standards. A subsequent project under a separate PAR is to create a single converged standard in the 5GHz band. PAR of Global 5GHz WLAN Standard (TGj)

LMSC Nov 9, 2000 approved formation of 5GSG (with contingencies of forming similar groups at ETSI BRAN and MMAC were fulfilled)
