The Wi-Fi Alliance will not change the basic requirements of its IEEE 802.11n certification process when the current draft specification gives way to a formal standard later this year.

The industry group's decision ensures that hundreds of already approved products will be interoperable with gear based on the final standard, avoiding integration headaches that might have plagued users trying to add to their networks.

The 11n standard for high-speed wireless LANs set off a battle among vendors that lasted so long that the Wi-Fi Alliance, the main industry group, began certifying products based on a draft version of the specification in 2007. About 600 products have been certified based on that draft, according to the group, allowing consumers to buy routers, access points and client devices with confidence they will work with other Draft-11n gear.
