WebWhat is MIMO (multiple input, multiple output)? MIMO (multiple input, multiple output) is an antenna technology for wireless communications in which multiple antennas are used at both the source (transmitter) and the destination (receiver). WebApr 2, 2024 · MIMO technology uses multiple antennas to transmit and receive signals in the wireless communications field. Mainly applied in the Wi-Fi (also known as WiFi) and mobile communications fields, this technology can greatly improve the system capacity, coverage range, and signal-to-noise ratio (SNR).
