You can already buy new products that are compliant with the proposed 802.11n wireless standard, they even promise speeds of data transmission much higher than 802.11g. The problem is that the draft of the standard failed to gain approval at a working group meeting of the IEEE on Tuesday. Draft 1.0 needed 75% support to move forward. Rejection of a draft is not uncommon at this stage of the process, but this one is different because manufacturers are already selling chips and devices based on the draft. Major changes to the next draft to gain approval could challenge the efficacy of those devices. Experts believe that the changes will indeed be major, while the manufacturers who have already committed to the draft standard are predictably saying that their products will remain relevant and effective.
Comments and potential changes to the standard will now be submitted to the working group. There has been some dispute over whether chips that meet the now rejected draft lived up to performance and interoperability claims made by chip makers.
