IEEE 802.11aa-2012 includes a more sophisticated prioritization to balance network management information and data traffic to achieve better network performance as a result.
Also, 802.11aa integrates new Quality of Service (QoS) features, including group-addressed transmission service, stream classification service, management of overlapping networks and support for the IEEE 802.1Q Stream Reservation Protocol. According to the IEEE, the changes deliver improved management of audio/video stream quality, link reliability and application performance when channel capacity is insufficient or when WLANs overlap on the same radio channel.
“IEEE 802.11 is constantly being refined and innovated to address the emerging needs of the marketplace, and these two new standards are further proof of that fact,” said Bruce Kraemer, chair of the IEEE 802.11 working group. “Both of these amendments specify timely enhancements to the base standard that continue to expand IEEE 802.11’s use in more and more business and residential applications around the globe.”
The IEEE 802.11aa is available for purchase at the IEEE Standards Store. The PDF is priced at $5, while the printed version is sold for $99.
