What is new in the 802.11n final wireless standard ?

There are three key improvements in the new 802.11N Wireless standard.

The heart of wireless N is the addition of MIMO Spatial Division Multiplexing (SDM). It allows for transferring multiple independent data streams simultaneously using multiple antennas at both the transmitter and receiver to help increase throughput.

There's also "channel bonding" that lets users combine two wireless frequencies for better performance and reliability.

Finally, a "packet aggregation" feature reduces the amount of overhead data needed to transfer files, allowing more room in the pipe for actual data.
