Pre-standard Wi-Fi products to be certified

The Wi-Fi Alliance will begin certifying early 802.11n products before the standard is complete, to encourage Wi-Fi momentum

The Wi-Fi Alliance plans to begin certifying next-generation Wi-Fi products starting in 2007 before the 802.11n standard is fully complete, a decision that should ease consumers' concerns about buying pre-standard products.

The industry group, which has certified products for all the preceding 802.11 standards, including 802.11a, 802.11b and 802.11g, said on Monday that it is taking a two-phased approach to the 802.11n certification process.

Starting in March, after the IEEE's (Institute of Electrical and Electronics Engineers) general membership has accepted the new draft proposal for 802.11n, the Wi-Fi Alliance will begin certifying products. Once it becomes a full standard, the alliance will update its certification process to comply with the standard. The group hopes to make sure that the standard products will also interoperate with the pre-standard products it certifies.

Frank Hanzlik, managing director of the Wi-Fi Alliance, said it is important for the group to keep the industry moving towards a new Wi-Fi standard that promises to increase speeds to allow for new applications, such as video, to be distributed throughout homes using Wi-Fi.

The standard, which has been batted around for more than a year, was supposed to be finalised by early 2007. But the process has been delayed, and a final standard isn't likely to be completed until 2008.

Meanwhile, many companies have already begun selling pre-standard 802.11n equipment based on the first version of the draft standard.

"The combination of the standard being delayed a year, and the fact that there are already products on the market, made us come together and say it may not be in the best interest of the industry if we wait," Hanzlik said. "The products sold today don't interoperate. And without interoperability, users won't have the right kind of experience."

The Wi-Fi Alliance generally waits until a standard is complete before it begins certifying products. But it tried a similar two-phased approach with the 802.11i security standard when it was being developed. In 2003, the group began certifying products that complied with an interim subset of the standard called Wi-Fi Protected Access, or WPA. Then, in September 2004, when the standard was complete, it began certifying products compliant with WPA 2.

Dave Borison, director of product management for Airgo Networks, a company that pioneered the technology being used as the basis for the new 802.11n standard, is pleased about the Wi-Fi Alliance's decision to certify pre-standard products.

"I think it will shepherd the whole industry forward," he said. "Right now, it's chaos. Consumers have no idea if they are buying products that can be upgraded or if they will work with other certified Wi-Fi gear."
