Multiple-Input Multiple-Output (MIMO) wireless routers use an array of external or internal antennas to offer an increase in both speed and range when compared with standard 802.11g and 802.11b wireless products. MIMO wireless routers let you transfer and receive at twice the rate because they have two transmitters and two receivers. This gives you a better quality signal and better coverage. Some of the MIMO wireless router models available in the market are:
Belkin G+ MIMO Wireless Router
D-Link Super G with MIMO Wireless Router DI-634M
Cnet Wireless MIMO Router CWR- 903
LevelOne NetCon WBR-5400 MIMO Wireless Broadband Router
