WiFi Update

3:50 PM -- For those of you keeping tabs on the progress of the faster 802.11n wireless LAN standard, the Wi-Fi Alliance has now certified that 140 devices using the draft n specification will work together.

The alliance first began testing devices based on the draft 2.0 802.11n specification in Jume this year. The faster draft 802.11n specification provides maximum data transfer rates in excess of 500 Mbit/s and increased range over earlier standards. 802.11n achieves its rate hikes using multiple-input/multiple-output (MIMO) antenna technology, which hikes up the data transfer rates and steady throughput of the WiFi network by combining signals for a more accurate picture of data transfers. (See WiFi Alliance Promises N-Harmony.) The products certified include access points, home routers, and PC cards. Naturally, there's no final word yet on when the actual 802.11n standard will be ratified by the Institute of Electrical and Electronics Engineers Inc. (IEEE) . It is possible it could happen before the end of next year, or, you know, in 2009!
