Acronym for
multiple-in, multiple-out.
MIMO (multiple-in, multiple-out) takes advantage of
multiplexing to increase wireless
bandwidth and range. MIMO
algorithms send information out over two or more antennas and the
information is received via multiple antennas as well. On normal radio,
multiplexing would cause interference, but MIMO uses the additional pathways to
transmit more information and then recombines the signal on the receiving end.
MIMO systems provide a significant capacity gain over conventional single
antenna systems, along with more reliable communication. The benefits of MIMO
lead many to believe it is the most promising of emerging wireless technologies.
