This month, the IEEE 802.11n working group selected the TGn Sync proposal over the competing WWise proposal with a simple majority but could not immediately attain the 75 percent approval necessary to confirm the proposal as the first draft of the standard. Compromise between the backers of TGn Sync and the extant WWise proposal is now necessary. According to Airgo Networks representatives, some of the issues of contention are:
Whether 40MHz or 20MHz channels should be mandatory: TGn Sync favors 40MHz channels for improved capacity, but this may take longer to implement and may conflict with regulations in Japan.
The number of mandatory data rate modes.
The quantity and usefulness of proposed extensions to the 802.11 MAC (media access control) sublayer.
If a compromise is not attained after the next few meetings of the working group, the WWise proposal will be reintroduced. The next working group meeting is scheduled for May 13-15 in Queensland, Australia. Stay tuned.
