What Is Wireless-N?
Q: What is Wireless-N (draft 802.11n)?
A: Wireless-N draft 802.11n version 1.0A: The 802.11n standard will be the next generation of high-speed Wi-Fi, capable of delivering the range and capacity to support today’s most bandwidth-hungry applications, like streaming HD (High Definition) video, voice and music. Currently approved for 1.0 draft status by the IEEE (Institute of Electrical and Electronic Engineers) Task Group-N committee, final 802.11n specification is expected to be approved in 2008.

Q: How does Wireless-N work?
A: Wireless-N uses multiple technologies such as MIMO (Multiple Input, Multiple Output), which utilizes multiple radios to transmit and receive at the same time to maximize wireless networking performance. While MIMO itself is not a standard, it is the underlying technology behind the throughput increase in 802.11n. These multiple radios transmit multiple streams of data called “spatial streams.” The higher the number of spatial streams, the higher the throughput. Numerous streams of content can move over the same channel at the same time, multiplying the capacity of each channel. Wireless-N can further double the capacity by optionally using two 20MHz channels. With smart antenna technology, strong, weak and reflected signals are combined into one data stream for maximum range–virtually eliminating dead spots throughout your home or office.
