MIMO Systems, or Multiple Input Multiple Output systems, are a technology used in wireless communication that employs multiple antennas at both the transmitter and receiver ends. This setup allows for the simultaneous transmission and reception of multiple data streams, significantly increasing the capacity and reliability of the communication link. By utilizing spatial diversity, MIMO Systems can improve signal quality and reduce interference, making them essential for modern wireless standards like Wi-Fi and 4G/5G networks. This technology enhances data rates and overall performance, enabling faster and more efficient communication in various applications, from mobile devices to broadband services.
