http://www.theregister.co.uk/2004/09/02/wi-fi_proThe Wi-Fi Alliance formally began issuing WPA 2 certificates yesterday, as eight products received the right to use the organisation’s second-generation wireless security brand.
WPA 2 is derived from 802.11i, the wireless security standard finally ratified by the IEEE in July. WPA 2 essentially mandates the use of the AES encryption standard, thus far only offered by some vendors as an option alongside WPA’s Temporal Key Integrity Protocol (TKIP).
WPA essentially provided components of 802.11i that didn’t require hardware acceleration.
The WFA will next introduce its Wireless Mulitmedia (WMM) marque, which is expected to begin issuing certification for later this month. A subset of the 802.11e quality of service standard, WMM essentially provides wireless traffic a range of priorities, depending on the kind of data they contain. Time-dependent information, like video or audio, for example, will get priority over, say, email traffic.

The Wi-Fi Alliance (WFA) will formally unveil its Wi-Fi Multimedia (WMM) certification next week, and with it the first ten products that can carry the WMM brand.
Just as the organisation’s Wi-Fi Protected Access (WPA) security specification pre-dated the ratification of the IEEE 802.11i standard from which it was derived, so too is WMM as sub-set of the upcoming quality of service standard 802.11e.
The WFA unveiled WPA 2 earlier this week.
According to WFA CEO Frank Hanzlik, 802.11e takes two approaches to improving the performance of time-dependent data, such as video: prioritising such traffic and segmenting the bandwidth. The two approaches are dubbed Wireless Media Extensions (WME) and Wireless Scheduled Media (WSM), respectively.
Hanzlik told The Register that WMM will initially use WME. WSM support is likely to come sometime in the first half of 2005 when 802.11e is finally ratified, he said.
“It’s our intention to remain very aligned with the IEEE,” he added.
When 802.11e is ratified, WMM is not likely to be upgraded to WMM 2, as the WFA has done with WPA, Hanzlik said. At this stage, the organisation will instead brand QoS as ‘WMM with Scheduled Media’, for example. That will allow the WFA to extend WMM with further QoS-related technologies as they emerge, Hanzlik said.
WMM will be a baseline technology to which other features can be added on, he said
