About Wireless N 802.11n
With speeds of up to 600 Mbps, the emerging 802.11n standard is the next generation of wireless networking, delivering the speed, range, and reliability to support the most bandwidth intensive applications. 802.11n incorporates multiple technologies including Spatial Multiplexing MIMO (Multi-In, Multi-Out), 20 and 40 MHz channels, and dual bands (2.4 GHz and 5 GHz) to generate the high speeds and at the same time communicate with legacy 802.11b/g devices. The 802.11n specification was approved in September 2009. Manaufacturers are committed to collaborating with the IEEE and WiFi Alliance to ensure that 802.11n devices will interoperate at the highest speeds without degrading performance of neighboring 802.11b/g wireless networks.
