This is very interesting news. The WiFi Alliance is considering the certification of single-stream 802.11n product.
The Wi-Fi Alliance said it has started testing single-stream access points and routers that use 802.11n technology.
In an email to SmallNetBuilder, Kelly Davis-Felner, the WFA's Marketing Director said that testing had
started last week.
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 the mark shown above (or a version without the "a" for single-band products).
According to Alliance literature, the single-stream certification indicates that the product is Wi-Fi CERTIFIED to the previous standards shown, and also contains some of the features of Wi-Fi CERTIFIED n. These products may be referred to as “wireless-n” or “Wi-Fi n” by manufacturers.
Single stream products typically support a maximum connection rate of 65 Mbps using the default 20 MHz channel bandwidth and 135 Mbps using 40 MHz channel bandwidth.
