16 November, 2001 doc. : IEEE 802. 15 -01/490 r 2 Presentations • 1 day of non-proposals – There have been many compromises proposed • • CCK-OFDM CCK+OFDM PBCC + CCK-OFDM DQPSK with 10/11 Reed-Solomon coding • Vote on closed balloting – Failed Submission James P. K. Gilb, Mobilian

16 November, 2001 doc. : IEEE 802. 15 -01/490 r 2 Confirmation of CCK-OFDM • Vote at 8: 30 am (closed door, written ballot) – 4 months after down selection – Failed 83/67/4 (55% approve, 75% required) • Compromises suggested – Straw polls on many options – Discussed withdrawing the PAR • Vote Thursday at 4: 15 pm on compromise – – Submission B plus A equals G CCK + CCK-OFDM + PBCC-22 CCK-OFDM and PBCC are optional (and incompatible) Passed 116/36/0 (76. 3%/23. 7%) James P.
