What is Multiple-Input Multiple-Output?

Multiple-Input Multiple-Output (MIMO)
is a wireless technology that uses multiple transmitters and receivers to transfer more data at the same time. All wireless products with 802.11n support MIMO. The technology helps allow 802.11n to reach higher speeds than products without 802.11n.

To implement MIMO, the station (mobile device) or the access point (AP) must support MIMO. For optimal performance and range, both the station and the AP must support MIMO.

Wi-Fi, LTE; Long Term Evolution, and many other radio, wireless and RF technologies are using the new MIMO wireless technology to provide increased link capacity and spectral efficiency combined with improved link reliability using what were previously seen as interference paths.

There are many MIMO wireless routers on the market, and as this RF technology is becoming more widespread, more MIMO routers and other items of wireless MIMO equipment will be seen.

Typical modern WiFi router using MIMO Technology with multiple antennas.

MIMO an antenna technology for wireless communications in which multiple antennas are used at both the source (transmitter) and the destination (receiver). The antennas at each end of the communications circuit are combined to minimize errors and optimize data speed.

MIMO Configuration

A 2x2 MIMO configuration is 2 antennas to transmit signals (from base station) and 2 antennas to receive signals (mobile terminal).

2×2 MIMO CONFIGURATION

MIMO HISTORY

MIMO is often traced back to 1970s research papers concerning multi-channel digital transmission systems and interference (crosstalk) between wire pairs in a cable bundle: AR Kaye and DA George (1970), Branderburg and Wyner (1974), and W. van Etten (1975, 1976).

Invention

If we use high speed Wi-Fi and 4G or LTE on your smartphone, you've got Arogyaswami Paulraj to thank. His wireless communications technology – MIMO, or multiple input, multiple output – is the core driver that increases performance in the latest wireless systems.

How Multiple Input / Multiple Output (MIMO) For Faster Mobile Data works:

A new generation of wireless technologies as well as LTE and LTE-Advanced make data intensive applications such as gaming and mobile video possible. MIMO connections get more use from the bandwidth available by using multiple channels. This enables these types of applications.

Instead of using a single channel, MIMO establishes multiple connections between a user and the network by using the same frequency band in two or four channels. MIMO does not avoid multi-pathing, but deliberately finds multiple paths for RF signals.

MIMO can only work if multiple receivers, transmitters and antennas are installed into each mobile device. In a MIMO-enabled network, a mobile device will send and receive two separate wireless signals instead of one.

In a MIMO network, the base station antennas can receive more than one signal. MIMO connections use advanced signal processing algorithms and innovative engineering to avoid the negative effects of multi-pathing. At the same time, the speed at which users can watch videos, play games and access the internet is increased significantly.

MIMO is effectively a radio antenna technology as it uses multiple antennas at the transmitter and receiver to enable a variety of signal paths to carry the data, choosing separate paths for each antenna to enable multiple signal paths to be used. ... By using MIMO, these additional paths can be used to advantage.
