802.11n builds upon earlier 802.11 standards by totaling MIMO (multiple-input multiple-output).MIMO employs multiple transmitter and receiver antennas to allow for augmented data throughput via spatial multiplexing and augmented range. It is approximately 4 times that of 802.11a and g and presents 100 megabit per second (Mbps) throughput. Future 802.11n systems that include additional spatial streams will bring up to 600 Mbps with channel bonding.

The n standard presents augmented coverage area (twice the variety), higher throughput and better Quality of Service. As well, 802.11n will support all main platforms, including consumer electronics, individual computing, and handheld platforms. Picture quality necessary by HD video can be attained with 802.11n wireless networks.

802.11g standards employ the 2.4 GHz (gigahertz) band. They will undergo intrusion from microwave ovens, Bluetooth devices, cordless telephones, baby and security monitors and other appliances employing this band. The new standard is also backwards attuned with older a and g standards.
