The 802.11n version of Wi-Fi promises to deliver higher speeds and greater reliability than earlier versions.
The WiFi Alliance has announced the first list of products that meet its 802.11n Draft 2.0 specification. These products follow the preliminary specifications that were announced in March and should be upgradable to the final 802.11n specification when that is released in 2008, although such upgrades are not guaranteed by the WiFi Alliance.
The products included in the WiFi Alliance's list are both commercial products and reference designs and will be used as part of the Alliance's testbed for interoperability testing.
The 802.11n version of Wi-Fi promises to deliver higher speeds and greater reliability than earlier versions. A number of manufacturers have announced plans to build wireless high-definition IPTV communications devices based on the standard, and access points labeled "pre-n" have been on the market for a few months.
However, computers able to use 802.11n have yet to be produced.
The list of commercial products and reference devices that meet the Draft 2.0 standard includes wireless access points and access cards for laptop and desktop computers as well as a chip set:

The WildPackets OmniPeek Workgroup Pro is also listed by the WiFi Alliance as a testbed software tool.
