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). The antennas at each end of the communications circuit are combined to minimize errors and optimize data speed.
The 802.11ac -2013 update, or 802.11ac Wave 2 , is an addendum to the original 802.11acwireless specification that utilizes MU-MIMO technology and other advancements to help increase theoretical maximum wireless speeds from 3.47 Gbps in the original spec to 6.93 Gbps in 802.11ac Wave 2 .
