MIMO (Multiple Input Multiple Output, pronounced my-mo) is a wireless technology designed to increase wireless bandwidth and variety by taking benefit of multiplexing. MIMO employs algorithms in a radio chipset to send data out over two or more antennas. The radio signals then reflect off a range of objects in the surroundings to create multiple paths used to carry more reports. This information is then recombined on the getting side by the MIMO algorithms. Current 802.11g technologies employ single transmitting and dual receiving antennas, MIMO uses multiple transmitting antennas. MIMO uses the additional pathways gives by the multiple antennas to transmit more data and then recombines the signal on the receiving end.

MIMO gives developments in wireless LAN (WLAN) throughput, range and dependability that will broaden the value of wireless for applications and permit for more throughput concentrated applications to run over wireless. Airgo's MIMO chip set completion broadcasts two distinct datastreams simultaneously at 54Mbps totaling 108Mbps (Airgo is a MIMO chip manufacturer).

Finally there should be an IEEE 802.11n standard for MIMO which assures to push wireless network data rates well above the 100Mbps mark which will expectantly fill those wireless dead spots most people knowledge around their home and office wireless network.

Certainly a new technology needs new (more expensive) hardware. Unluckily different manufactures products may not unavoidably work together with each other. Both wireless adapters and access points may have to be the same brand. Also, the best results are obtained with a true MIMO completion on both ends of the connection. "True MIMO" needs multiple antennas and radios on both the transmitting and obtain sides of the link. Expect MIMO hardware to be more luxurious at least in the beginning of its rise (or fall) to glory.
