MIMO [Multiple Input Multiple Output] radio frequency antenna networks allow for separate simultaneous radio transmissions because each AP [Access Point] or link is on different RF [Radio Frequencies]. MIMO [Multi-Input Multi-Output] antennas and multiple transmitter/receivers (also referred to as TX-transmit/RX-receive) or radios add additional client coverage and, most important, dedicated mesh links for backhaul data connections.

In a mesh wireless network, configuration can be six or more TX/RX radios in a single AP. This means that a multi-radio AP with six radios can support up to three non-overlapping radio modules and three backhaul transmissions in the 2.4 or 5 GHz frequency bands. That is, APs start sending packets even before all are received. An optimally designed mesh network allows simultaneous reduced interference (signal collision). Use of AES encrypted 802.11a provides many non-overlapping channels, reducing interference.
