MIMO (Multiple Inputs, Multiple Outputs) is the primary method used in 802.11n Wireless-N networks to increase throughput. Instead of having just a single radio, two or more radios simultaneously transit different spatial streams of data. By transmitting data in parallel, throughput is increased.
Additional MIMO-related techniques include Maximal Ratio Combining (MRC), Spatial Multiplexing (SM) and Space Time Block Coding (STBC).
