MIMO, which refers to a radio system that has multiple separate receive and transmit paths, is at the

heart of 802.11n. MIMO systems are described by the number of transmitters and receivers in the

system. For example, "two by one" or 2x1 refers to a system with two transmitters and one receiver.
