MIMO-based Wi-Fi routers utilize the same network protocols and signal ranges that non-MIMO routers do. The MIMO products achieve higher performance by more aggressively transmitting and receiving data over Wi-Fi channels. MIMO signaling technology can increase network bandwidth, range and reliability at the potential cost of interfering with other wireless equipment.
The specific number of antennas utilized in a MIMO Wi-Fi router can vary. Typical MIMO routers contain three or four antennas instead of the single antenna that is standard in all earlier forms of consumer Wi-Fi routers.
MIMO is a key element of the 802.11n Wi-Fi networking standard.
