802.11e Qos for Wireless

Multimedia 802.11e standard speeds up | The Register

The Wi-Fi Alliance says it will skip an interim certification for multimedia and voice over IP extensions to 802.11x, since it seems that the IEEE standards body will fast track the full standard, 802.11e, to be approved by June.
The body, which tests and promotes WLAN standards, had been planning to release a stopgap spec – in a two-step process similar to that for Wi-Fi security extensions, by which the Alliance released WPA as a move towards the full IEEE 802.11i standard.

This is a hot topic of research at the moment in Ireland.
