## What it is
MIMO (multiple-input multiple-output) is a wireless technique that uses multiple antennas at both the transmitter and receiver to multiply link capacity or improve reliability without extra bandwidth or power.
## How it works / why it matters
By exploiting the many independent paths in a multipath propagation environment, MIMO can either send several data streams in parallel over the same frequency (spatial multiplexing, boosting throughput) or send the same stream redundantly across paths (diversity, boosting reliability); beamforming steers energy toward the receiver. Information-theoretically, an $M \times N$ MIMO channel offers a capacity that grows roughly with $\min(M,N)$, which is why massive-MIMO arrays are central to Wi-Fi, LTE, and 5G. It turns the once-troublesome multipath of the wireless channel into a resource.
## Signs & universals
Instantiates signal and network, and depends on noise and probability — it exploits the statistics of a noisy multipath channel to raise the capacity of the wireless network.

## From the Real GENERATIVE library
> In radio, multiple-input and multiple-output (MIMO) (/ˈmaɪmoʊ, ˈmiːmoʊ/) is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation.[1][2] MIMO has become an essential element of wireless communication standards including IEEE 802.11n (Wi-Fi 4), IEEE 802.11ac (Wi-Fi 5), HSPA+ ( ([Wikipedia](https://en.wikipedia.org/wiki/MIMO))
