a set of multiple-input and multiple-output technologies for multipath wireless communication, in which multiple users or terminals, each radioing over one or more antennas, communicate with one another.

Multiple-input multiple-output radar is an extension of a traditional radar system to utilize multiple-inputs and multiple-outputs (antennas), similar to MIMO techniques used to increase the capacity of a radio link.

WiMAX MIMO refers to the use of Multiple-input multiple-output communications technology on WiMAX, which is the technology brand name for the implementation of the standard IEEE 802.16.
