is a MIMO?
A technique for enhancing
wireless throughput and range by taking advantage of new multiplexing
MIMO send information out over two or
more antennas. The radio signals reflect off many objects, creating
multiple paths that in conventional wireless cause interference and
signal fading, while MIMO uses these paths to carry more information,
which is recombined on the receiving side by the MIMO algorithms.
a lot of wireless-LAN vendors expect
that some form of MIMO will be the basis of work starting in the IEEE
802.11n Task Group, creating a specification for WLANs having at least
100M bit/sec throughput. The 3rd
Generation Partnership Project, is a collaboration of telecom
standards groups, also is considering MIMO techniques for use in
cellular mobile networks.
MIMO doubles the spectral efficiency
compared with that of today's Wireless LANs. The maximum data rate for
802.11g and 802.11a networks is 54M bit/sec, while actual throughput is
as low as 20M to 30M bit/sec. Current MIMO techniques can reach
constant throughput of 108M bit/sec.
