Quite a long time, manufacturers produce different network devices supporting standard 802.11n Draft 2.0, despite the fact that the standard really was adopted only in September. For more than a year on the market are routers, network cards and USB-adapter with support for Draft-N. In adopting the final specifications of 802.11n IEEE Standard reported that many existing products on the market supports them. Now, Wi-Fi Alliance announced a new certification program "Wi-Fi Certified n", which introduces new logos and labels for products 802.11n. Representatives of the Wi-Fi Alliance reported that this program helps to ensure the best operation of new devices in the next expansion of Wi-Fi standard and allows for the evolution and realization of production of the next generation Wi-Fi.

The program Wi-Fi Certified N confirms the requirements set forth in the specification, and adds some additional technical conditions to provide additional capabilities, including simultaneous transmission of three-dimensional flows, packet aggregation of A-MPDU for more efficient data transmission, STBC coding for multiple antennas for reliability, etc. The new logo is longer and shows all the protocols, starting with early versions of Wi-Fi, which supports specific device. Under the new certification program, some devices will be marked as "Wi-Fi CERTIFIED dual-stream n" (Dual-certified for Wi-Fi n) or "Wi-Fi CERTIFIED multi-stream n" (certified for multi-Wi-Fi n).

"Given the wide range of devices supporting 802.11n, and their various possibilities, the launch date certification program Wi-Fi is an important next step for the industry", ─ says Fodeyl Victoria (Victoria Fodale), an analyst at In-Stat. ─ "Guide Wi-Fi Alliance through testing, as well as through the updated branding and labeling will continue to provide assistance to users, providing advanced features Wi-Fi technology."
