What is the purpose of multiple-input multiple-output (MIMO) technology?

The purpose of multiple-input multiple-output (MIMO) technology is to improve communication performance by utilizing multiple antennas for both transmission and reception. This innovative approach allows MIMO systems to send and receive more than one data signal simultaneously through the same radio channel. By doing so, MIMO increases the capacity and efficiency of the communication link, enabling higher data rates and more reliable connections.

MIMO achieves this improvement through spatial multiplexing, where different data streams are sent over multiple antennas. This technique takes advantage of multipath propagation—where signals reach the receiver via multiple paths due to reflection, diffraction, and scattering—thereby enhancing the signal quality and data throughput without requiring additional bandwidth or increased power levels.

While other options highlight aspects of wireless communication, they do not capture the core function of MIMO technology. For instance, reducing power consumption, increasing coverage distance, or simplifying network setup does not fundamentally describe the pivotal role of MIMO in boosting data transmission efficiency through multiple antennas.
