802.11n802.11n boosts Wi-Fi data rates to between 100 Mbps and 300 Mbps, and the multiple-input, multiple-output technology used by 802.11n offers the potential for better coverage in some situations. 802.11n is likely to be a long-lived standard that will define Wi-Fi performance for several years.
High-speed Wi-Fi is desirable to stream media around the home and office. From an organisational perspective, 802.11n is disruptive; it's complex to configure, and is a "rip and replace" technology that requires new access points, new client wireless interfaces, new backbone networks and a new power over Ethernet standard.
However, 802.11n is the first Wi-Fi technology to offer performance on a par with the 100 Mbps Ethernet commonly used for wired connections to office PCs. It is, therefore, an enabler for the all-wireless office, and should be considered by companies equipping new offices or replacing older 802.11a/b/g systems in 2009 and 2010.
