New IEEE 802.11(TM) Amendments Designed to Improve Audio/Video Streaming and Wireless Network and Application Performance
IEEE 802.11aa(TM)-2012 Specifies New QoS Features for More Robust Audio/Video Applications; IEEE 802.11ae(TM)-2012 Defines Prioritization of Management Frames
IEEE, the world's largest professional organization advancing technology for humanity announced the publication of two IEEE 802.11™ amendment standards. IEEE 802.11aa™-20121 supports more robust audio and video streaming for IEEE 802.11 applications. IEEE 802.11ae™-20122 improves network performance by prioritizing management frames sent on an IEEE 802.11 wireless link.
“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.”
IEEE 802.11aa contains several important 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. The enhancements for the 802.11 MAC (Medium Access Control) layer are intended to deliver a host of benefits, including improved management of audio/video stream quality, link reliability and application performance in instances such as when channel capacity is insufficient or when WLANs overlap on the same radio channel. IEEE 802.11aa is available for purchase at the IEEE Standards Store.
IEEE 802.11ae defines a mechanism for prioritizing management frames and a protocol for communicating prioritization policy. IEEE 802.11ae enables a more sophisticated prioritization capability that balances the need to move both network management information and data traffic and yields improved performance of IEEE 802.11 networks and the applications that use them. IEEE 802.11ae is available for purchase at the IEEE Standards Store.
