The WWiSE proposal has brought Motorola on board and adopted parts of their proposal: Task Group N in the IEEE 802.11 Working Group voted a few weeks ago to continue forward on just WWiSE (Broadcom and many others) and TGn Sync (Atheros and many others). Qualcomm signed on to TGn Sync when their proposal didn't make the cut, and the Motorola notion was also voted down. WWiSE's press release says elements of Motorola's plan will improve WWiSE's robustness and range.
This is a key jockeying move because the next meeting could achieve a majority vote on a single proposal which would then move through drafts to final ratification probably in late 2006. A simple majority selects a winning proposal, but changes in drafts must be approved by a 75-percent super majority. Both TGn Sync and WWiSE are willing to compromise, but both want their drafts to be the starting point. WWiSE says they have a more minimal approach on top of which more options can be added without being mandatory parts of the specification; TGn Sync says their more thorough approach gives the standard more legs and more competitive power.
