802.11n is a draft high-speed wireless standard. In addition to throughput, 802.11n will significantly enhance the reliability and range of existing 802.11 networks.
The standard defines procedures by which throughputs greater than 100Mbps and significant range improvements also are possible. Some of the important features that are included in current 802.11n draft are multiple-input multiple-output (MIMO), channel bonding and packet aggregation.
The MIMO technology uses several antennas to move multiple data streams from one place to another. Instead of sending and receiving a single stream of data, MIMO can simultaneously transmit three streams of data and receive two. This allows more data to be transmitted in the same period of time.
The IEEE 802.11n not only extends the range, or the distance over which data can be transmitted, but also increases the amount of data that can be transmitted.
