Before anyone asks:
==History==
Jack Winters at Bell Laboratories filed a patent on wireless communications using multiple antennas in 1984.
Jack Salz, also of Bell Laboratories published a paper on MIMO in 1985, based on Winters' research.
Winters and many others published articles on MIMO in the period from 1986 to 1995.
In 1996, Greg Raleigh and Gerald J. Foschini invented new approaches to MIMO which increased its efficiency. Greg Raleigh is the founder of Airgo Networks, which claims to be the inventor of MIMO OFDM, offering a "pre-N" chipset called "True MIMO". However, it is unclear if hardware based on this chipset will be compatible with other devices once the 802.11n-standard is ratified.
