802.11n and its opportunities for enterprises

Wireless networks have reached new levels of performance with the introduction of 802.11n. The primary goal of 802.11n is high throughput and high range using the frequency bands traditionally used by 802.11a, 802.11b and 802.11g products. The 802.11n products achieve this goal by using MIMO (Multiple input, Multiple output) antennas, by making the 802.11 MAC more efficient and by improving the OFDM PHY. The 802.11n protocol also supports interoperability with traditional 802.11a, 802.11b and 802.11g devices. These enhancements now provide the same capabilities as a 10/100 LAN yet with the benefit of full mobility for voice, video and data. So there is no longer any benefit to being tethered to a LAN and you get the productivity benefits of full mobility both indoor and outdoor.
