The logo will be placed on all certified products using the technology. 802.11n promises up to five times the throughput and twice the range of the previous fastest standard, 802.11g, and it works in both previous frequencies: 2.4GHz and 5GHz.

The publication date for the finalised standard, which has to be approved by standards body the Institute of Electrical and Electronics Engineers (IEEE), has been repeatedly pushed back. Some observers claim that infighting between vendors is the cause. The Wi-Fi Alliance estimates that 802.11n will only be ratified in March 2009, but it announced last year that it was to start certifying products early because it would not be "in the best interest of the industry" to wait.

"Draft 2.0 is widely considered to provide a stable foundation for commercial products," explained Karen Hanley, senior director at the Wi-Fi Alliance.
