Wireless has always been a complex technology and many security integrators have taken it into account only when everything else failed. Interferences, antenna alignment, line of sight and lightning are some of the issues that you have to face when deploying a wireless system. These tend to scare some people away. Thanks to a new technology development in radio technology called multiple inputs multiple outputs (MIMO), wireless backbone systems have now become a friendlier option for integrators looking for a transmission system that is reliable, cost effective, and easy to deploy.

MIMO technology, which is a form of smart antenna technology (a technology where antenna arrays with smart signal processing algorithms identify spatial signal signatures — such as the direction of arrival of a signal — and then use them to calculate beamforming vectors to track and locate the antenna beam on the mobile/target), has recently revolutionized the world of wireless transmission by offering a serious increase in data throughput and range without additional transmit power or spectrum usage. It requires the transmitter and the receiver to have multiple antenna. The greater performances are achieved by creating signal uncorrelation thanks to the multiple antenna.
