What is MIMO

Multiple input multiple output (MIMO) is an antenna system that consists of M transit antennas and N receive antennas. The MIMO technology allows spaces to become the resources used to improve performance and increases the coverage range of the wireless system.

The MIMO system generates multiple spatial flows with each antenna generating a maximum of one spatial flow. The single in single out (SISO) system sends or receives one spatial flow (one copy of signals) at a time. The MIMO technology allows multiple antennas to send and receive multiple spatial flows (multiple copies of signals) simultaneously and to differentiate the signals sent to or received from different spaces. An 802.11n device supports up to 4x4 MIMO, a maximum of four spatial flows, with a rate of up to 600 Mbit/s.
