Wi-Fi Networking News got tipped off by an anonymous IEEE member (it wasn't us, we only joined for the magazines) that the 802.11n draft is going to be very delayed.
Instead of receiving the standard 2,000 comments on the draft, the committee received 12,000. Thus, the vote is again going to be nowhere near the 75% required to ratify the draft.
Their guess, November '06 or January '07 for a draft. That means higher speeds will have to wait. But if you want broader coverage, current generation MIMO gear can provide it with their Multiple-In-Multiple-Out antennas. But those Draft-N device look like an even worse idea now if you want compatibility with future N gear.
