March 2005 doc. : IEEE 802. 11 -05/0190 r 0 Self Proclaimed Advantages • SYNC – Further along technically and better documented – Faster to approval • Wwise – Added six members – WWi. SE has an efficient and streamlined design – Detailed and stable specification, suitable for immediate progress to Draft 1. 0 • Key differences may be in: – – Submission MIMO inter-leaver design Short cyclic prefix Efficient pilot tone usage Compact preambles 5 John Barr, Motorola/Jim Allen, Appairent Technologies

March 2005 doc. : IEEE 802. 11 -05/0190 r 0 Step 17 17. When one proposal is left, there shall be a confirmation roll call vote either in favor of the proposal or for none of the above. The proposal shall be required to achieve a 75% majority in order to be submitted to the IEEE 802. 11 n Editor as the initial technical specification. If the remaining proposal fails to achieve a 75% majority, the members who voted "no" shall be requested to provide to the chair their reason(s) for voting no and what would be required to change their vote to affirmative. The proposer shall have an opportunity to respond to the concerns of the no voters, after which a roll call vote will be taken to approve the proposal. • Requirement to have a reason to vote no was removed.
