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.

The triple play is the convergence of data, voice, and television (IPTV) across a single pipe: Wi-Fi's in-home dominance of data and increasingly voice and IPTV (with proprietary extensions) will be challenged, ABI Research says, by the latest versions of three standards that work over coax, electrical wiring, and phone wiring. ABI Research says that by 2011, over 45 million gateways will offer wired-based distribution of data, voice, and video. (The quadruple play, by the way, adds mobile voice.)
