« D-Link Has First Certified Draft N Devices | Main | Belkin's New Router Stands Up, Provides Info »
Tim Higgins uncovers an ugly fact about Wi-Fi certification of Draft N devices: The Wi-Fi Alliance is only testing devices for compliance with Draft 2.0 of 802.11n in 20 MHz channel mode in the 2.4 GHz band. There are three mechanisms designed for 2.4 GHz to made Draft N devices play nice with neighbors when in that wider mode. The Alliance told Higgins that there’s still too much debate over how this will be handled, and thus they aren’t testing for it. Devices should come configured to use only a single 20 MHz channel in 2.4 GHz, as the D-Link device that Higgins tested does; Apple’s 802.11n base station is locked to 20 MHz only in 2.4 GHz.
