This black paper provides detail on spatial multiplexing which can significantly increase data throughput as the number of resolved spatial data streams is increased. Each spatial stream requires its own TX/RX antenna pair at each end of the transmission. It is important to understand that MIMO technology, a major architectural element of 802.11n radios requires a separate radio frequency (RF) chain and analog-to-digital converter (ADC) for each MIMO antenna. This increasing complexity ultimately translates to higher implementation costs as higher-performance systems are required.

Nick, I want to give Ruckus some kind marketing award for publishing a “black paper”:)
