Following the ratification of the 802.11n standard, the Wi-Fi Alliance has kicked off the Wi-Fi Certified n program, an updated version of the Wi-Fi Certified 802.11n draft 2.0 program. The ‘new’ program keeps all the draft 2.0 requirements and adds testing for optional features like:
- Simultaneous transmission of up to three spatial streams
- Packet aggregation (A-MPDU), to make data transfers more efficient
- Space-time Block Coding (STBC), a multiple-antenna encoding technique to improve reliability in some environments
- Channel coexistence measures for “good neighbor” behavior when using 40 MHz operation in the 2.4 GHz band
“Wi-Fi Certified n builds on the success of our draft-n certification program and marks a point of maturity in 802.11n technology,” said Wi-Fi Alliance executive director Edgar Figueroa. “Our expanded testing and branding program helps ensure the best user experience in the context of the Wi-Fi industry’s continued innovation and the evolving landscape of products implementing next-generation Wi-Fi.”
