Now that the latest, fastest and final 802.11n
WiFi standard is up and running with the blessing of the I-EEE, the
Wi-Fi Alliance is now testing and certifying products that use the networking standard with a colorful new logo and taglines.
The program is intended to help both enterprise and consumer users of 802.11n-infused wares distinguish between products of different speeds and throughput capacities.
Also for the first time, the Wi-Fi alliance is testing and labeling 802.11n products with special optional enhancements, including:
- Test support for simultaneous transmission of up to three special streams;
- Packet aggregation to make data transfers more efficient;
- Space-time block coding (a multi-antenna encoding technique that improves reliability in some environments); and
- Channel coexistence that measures for “good neighbor” behavior when using 40 MHz operation in the 2.4 GHz band.
“I think that consumers are interested in these tagline distinctions,” said Sarah Morris, marketing manager for the Wi-Fi Alliance. “It’s also big news for enterprise users – a lot of times the WiFi (

In addition to supporting a wide range of devices tuned for varying performance criteria, the official “Wi-Fi CERTIFIED n logo program” removes the term “draft” from the logo.
Devices with particular feature sets may now use taglines in conjunction with the logo. For example, devices can now be designated “Wi-Fi CERTIFIED dual-stream n” or “Wi-Fi CERTIFIED multi-stream n” to indicate that they have passed tests for specific performance-enhancing features. The Wi-Fi Alliance (

“Given the wide array of 802.11n devices now emerging, and their varying capabilities,” said Victoria Fodale, senior analyst and market intelligence manager at In-Stat (
