What is MIMO?
It’s the next generation of Wi-Fi. MIMO stands for multiple input; multiple output. It’s an antenna technology for wireless communications in which multiple antennas are used at both the transmitter and the receiver. The antennas at each end of the communications circuit are combined to minimize errors and optimize data speed. MIMO generally operates in two modes: diversity mode and spatial multiplexing mode. In diversity mode, MIMO systems use multiple antenna arrays to maximize range and throughput between two wireless devices by choosing the best signal path between them. In spatial multiplexing Mode, MIMO systems use multiple signal paths to simultaneously transmit different data elements, where the receiver “recombines” the signals and data elements, ideally resulting in higher throughput.
A MIMO (Multiple-In-Multiple-Out) uses multiple radios and antennas to receive and transmit packets. A MIMO receiver simultaneously listens to incoming signals on multiple antennas. This technique takes advantage of the large differences in signal characteristics as seen by different antennas just a small distance apart. Using multiple antennas, and signal processing techniques “good signals” from each antenna can be combined to enhance the clarity of the original intended signal .This greatly increases ability to correctly receive packets and the overall range at which a radio can receive packets from other stations.
