Wireless N Certification

Small Net Builder notes that The Wi-Fi Alliance has started certifying single-stream access points and routers that use 802.11n technology. The 802.11n specification delivers speeds in excess of 100 Mbps primarily because it uses multiple radios on multiple channels. The protocol was also enhanced for better speed, but any radio using only a single radio didn’t qualify as “802.11n certified”.

Products that pass the test will not be Wi-Fi CERTIFIED n, since the 802.11n standard does not allow for single-stream access points and routers. Instead, they will carry a version without the “n” (for single stream products) or without the “a” (for single-band products).
