Multiple-Input Multiple-Output can be referred to as the communication channel created with multiple transmitters and receivers of an antenna to improve communication’s performance. Since their initial development in the year 1990, MIMO Wireless Communications have become integral part of the most forthcoming commercial and next generation wireless data communication system. MIMO is one among the several types of Smart Antenna Technologies. Nowadays MIMO techniques are used in different technologies such as WI-FI and LTE (long term evolution).

MIMO achieves space measurements to improve wireless systems’ capacity, range and reliability. It offers increase in the data throughput and link range without any additional bandwidth or transmitting power. MIMO antenna technology achieves this objective by spreading the same total transmit power over the antennas to accomplish an array gain that recovers the spectral efficiency (more bits per second per Hertz of bandwidth) or to achieve a diversity gain that increases the link reliability (reduced fading).

MIMO technology makes advantage of a natural radio wave phenomenon called multipath. MIMO uses multiple antennas to transfer multiple parallel data signals from a transmitter. In any urban areas, this multi path will bounce off trees, ceilings and other commercial buildings. The signals can reach their destination on their own at the receiver end in different directions.
