The Wi-Fi Alliance won't modify its certification tests for the ratified version of 802.11n: Changes aren't needed, the group says. This was completely expected, but glad to put yet another check in a box. The 802.11n standard will finally move from draft to completed status in September, although a vote taken recently has already formally closed the process.
PC World notes, from a briefing with the alliance, that there are four optional elements to 802.11n that will be certified in the future. Those optional parts were where changes took place after the mandatory elements were settled more or less in January 2007.
