Multiple-Input-Multiple-Output (MIMO) is a cutting edge antenna technology transmitting multiple data streams on multiple transmitters to multiple receivers. Multiple antennas are used at both the transmitter and the receiver to increase the odds of receiving the signal, especially when the link has Non-Line-of-Sight (NLoS). MIMO offer tremendous performance gains for wireless devices at a relatively low cost. The underlying technology of wimaxnear’s backhaul products XL-700 , XL-700-mimo Series and Wimaxnear’s Access Points sL-440-mimo are based on a combination of MIMO and OFDM technologies. High performance OFDM-MIMO combination enhances robustness using multiple transmitters and receivers, allowing the radios to completely take advantage of this antenna technology.

In real-world environments, signals reflect from various objects to reach the receiving antenna, hence a signal follows different distances before being received. This phenomenon is called Multipath propagation and causes interference and fading in non-MIMO radios. On the receiver side, having multiple receivers increases the amount of received power and also reduces multipath problems by combining the received signals for each frequency component separately. Hence, MIMO significantly improves the overall gain.
