Which 802.11 version introduced MIMO?

Explanation:
MIMO (multiple input, multiple output) uses multiple antennas at the transmitter and receiver to send and receive several data streams at once, boosting both speed and reliability by taking advantage of multipath propagation. This concept was first incorporated as a core feature with 802.11n, which combines multiple spatial streams (and often channel bonding) to dramatically increase throughput beyond what older standards could achieve. Earlier standards like 802.11b, 802.11a, and 802.11g relied on a single data path (SISO) and do not define MIMO capabilities, so they don’t provide the same performance gains.
