In 802.11n multiple antennas can be
Web802.11n adds multiple antennas to a physical layer based on coded Orthogonal Frequency Division Multi- plexing (OFDM); the single antenna (SISO) physical layer is otherwise quite similar to that of 802.11a/g. Each 20 MHz channel is divided into 52 data subcarri- ers, 4 more than in 802.11a/g, and 4 pilot subcarriers. WebIn its most basic conception, MIMO is technology that provides a multi-lane highway for 802.11n transmissions. When a transmitter can send multiple streams across a link, throughput improves. This description of MIMO is fairly passive, and does not provide a full picture of everything that a MIMO system can do.

WebSince Wi-Fi 802.11n uses OFDM (Orthogonal Frequency-Division Multiplexing) sub-carriers, third-order distortion products from these sub-carriers extend one bandwidth on each side of the Wi-Fi channel. 802.11n can operate in 20MHz or 40MHz modes. If operated in 40MHz mode, 40MHz of the 80MHz ISM band is consumed by the Wi-Fi channel.
