802.11n AP Devices support Multiple-Input-Multiple-Output (MIMO) antenna technology that uses multiple
antennas at both the transmitting end and receiving end to improve communication performance. The underlying technology
of these access point radio(s) are based on a combination of MIMO and OFDM (Orthogonal Frequency Division Multiplexing).
MIMO-OFDM combination radios solve interference, fading and multipath problems. Having multiple receivers at the
receiving end, increases the amount of received power and also reduces multipath problems by combining the received
signals for each frequency component separately. Hence, MIMO significantly improves the overall gain.
MIMO also uses Spatial multiplexing transmission technique to transmit independent and separately encoded data signals
from each of the multiple transmit antennas while reusing or multiplexing in the space dimension. These independent data
signals are called Spatial streams. The transmitting end of the device uses multiple radio Tx chains and signal paths to
simultaneously transmit different data streams, whereas the receiving end combines the Rx signals resulting in higher
throughput.
By increasing the number of receiving and transmitting antennas, the throughput of the channel increases linearly resulting in
high spectral efficiency.
