  1. 5GSG Liaison ReportPortland, Oregon Friday July 13, 2001 Tim Blaney, Mobilian

  2. 5GHz Study Group • Original Intent • Standard Harmonization - Single Global Standard for 5GHz WLANs • International effort • IEEE, ETSI, MMAC • Interim Objective • Interworking mechanism (TGj) • Interworking Proposal Concepts • Legacy backward compatibility maintained • Approaches so far based upon superframes using either DCF or PCF • HCF now being investigated • Likely to have no impact on Client, AP implementation only • Future plan • 5GHz Partnership Project now called 5WING Tim Blaney, Mobilian

  3. Motions • The SG recommends a motion to the 802.11 WG to reconsider the approval and forwarding to Exec Com of the PAR and 5 criteria for TGj (Doc 01-172, 01-173) • Approved in SG 13-0-13 • Motion to extend the 5GSG until the November plenary with the original goals as previously adopted, allowing a joint discussion with the other standards bodies (ETSI BRAN, MMAC) in the September 2001 meeting of the Joint SG to refine the aforementioned goals. • Approved in SG 21-2-2 • Background • Attempt to split the activity of the 5GSG into two groups • TGj and 5WING, where 5WING would look at future networks Tim Blaney, Mobilian

  4. Motion • Motion to amend something previously adopted • Amend the motion to substitute “rescind” for “reconsider” resulting in the following motion to be presented in the Closing Plenary: • The SG recommends a motion to the 802.11 WG to rescind the approval and forwarding to Exec Com of the PAR and 5 criteria for TGj (Doc 01-172, 01-173) Tim Blaney, Mobilian

  5. Coordination Remains Important • Three way Joint Study Group • (IEEE, ETSI/BRAN, MMAC) • Alternating ETSI and IEEE meeting venues • Co-located meetings in September 2001 • (More) Formal representation from MMAC Tim Blaney, Mobilian

  6. BRAN #24 Activity European Telecommunications Standards Institute BRAN#24 26 June to 29 June 2001 Sophia-Antipolis, France Executive Summary - BRAN24d141 1.      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. Tim Blaney, Mobilian

  7. MMAC Notice of Reorganization and Activities • MMAC letter to ETSI BRAN and IEEE (BRAN24d140) • Announcing reorganization • The Convergence Ad-hoc Study Group of MMAC-PC (a.k.a CASG) met on 23rd May, 2001 to discuss how to proceed towards convergence of MMAC wireless systems, HiperLAN2 and IEEE802.11a using 5 GHz band • CSMA WG work is done and will be closed soon. • 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. Tim Blaney, Mobilian

  8. Leadership • Bruce Kraemer – current chair in 5GSG as authorized by IEEE 802.11 • Jamshid Khun-Jush is vice chair • Reorganization • Nominate TK Tan as chair in 5GSG • Nominate Bruce Kraemer as co-vice chair • Any other nominations from the floor? • A recommendation from 5GSG subject to approval by Stuart in 802 WG • Result: Unanimous consent (37 attendees) Tim Blaney, Mobilian

  9. Appendix Informational and Background Material Tim Blaney, Mobilian

  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 (10th ed.), Section 35, pg 293 ff Tim Blaney, Mobilian

  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 (10th ed.), Section 35, pg 293 ff Tim Blaney, Mobilian

  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 (10th ed.), Section 37, pg 304 ff Tim Blaney, Mobilian

  13. PAR of Global 5GHz WLAN Standard (TGj) 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. Tim Blaney, Mobilian

  14. 5GHz Standardization Roadmap IW additions IEEE 802.11a (wireless Ethernet) IEEE 802.11e/f/h (QoS, Security, DFS/TPC, ..) Joint SG Requirements Coexistence Inter-working Spectrum 5WING Partnership Project (BRAN/IEEE/MMAC) single global standard Inter-working Standards Revisions 5GWIAG BRAN-HL/2 (wireless ATM, IP) Home Profile HE phase2 UMTS - interworking Public Access IW additions 2000 2001 MMAC also participating Today Tim Blaney, Mobilian

  15. History of 5GSG Formation • Liaisons on PHY during creation of 802.11a and HL2 (’98-’99) • Substantial harmonization • Initiated by 5GWLIAG (May 2000) – to address problems of multiple standards at 5Ghz space • Letters exchanged on request to recognize 802.11a as a member of HL2 (Jul 2000) • Led to ETSI joining the Sept 2000 IEEE meeting • Creation of Joint 5GSG (Sept 2000) • Alternative meeting venues • 5Ghz Global Standardization and Convergence discussion - IEEE September meeting, Scottsdale • Industry consensus towards global standardization at 5Ghz • Request for an 802.11 Study group (with coordination with ETSI BRAN and MMAC) to address these issues. • LMSC Nov 9, 2000 approved formation of 5GSG (with contingencies of forming similar groups at ETSI BRAN and MMAC were fulfilled) Tim Blaney, Mobilian
