IEEE Hilton Head Accomplishments Motions: May 2001 IEEE Hilton Head Accomplishments Motions: PProposed that we extend the 5GSG to the next joint plenary. Motion passed in study group 36/0/0 Motion passed in plenary 74/6/4 PProposed that we pursue the creation of a 5GHzPP as a vehicle for establishing a single global standard. Motion passed in study group 23/0/1 PPAR document (11-01-172) passed in plenary 41/8/17 P5 Criteria document (11-01-173) passed in plenary 42/6/13 Bruce Kraemer, Intersil

9. Scope of Proposed Project: May 2001 9. 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. 10. 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. Bruce Kraemer, Intersil
