section Introduction Revolutionary N Wireless Technology with MIMO (N MIMO) 1 Your Belkin N Wireless Router uses a new smart-antenna technology called Multiple Input Multiple Output (MIMO). N MIMO complies with the IEEE draft 802.11n specification. It increases speed, range, 2 reliability, and spectral efficiency for wireless networking systems. The element that makes Belkin's N MIMO technology different 3 from a conventional radio is the use of multiple antennas and two simultaneous data streams to deliver wireless transfers around your 4 home or office. A conventional radio uses one antenna to transmit a data stream. Belkin's N MIMO, on the other hand, uses two antennas. This design helps combat distortion and interference. Belkin's N 5 MIMO is multidimensional. It builds on one-dimensional smart-antenna technology by simultaneously transmitting two data streams through 6 the same channel, which increases wireless capacity. Another element that enhances Belkin's N MIMO is the use of 7 aggregation as specified in the draft 802.11n specification. By shortening the space between packets and combining multiple smaller packets into one larger packet, Belkin's N MIMO can transmit more 8 data through available bandwidth. 9 Think of conventional radio transmission as a two-lane highway. The speed limit governs the maximum allowable flow of traffic through that lane. Compared with conventional radios, one-dimensional smart 10 antenna systems help move traffic through that lane faster and more reliably-analogous to a four-lane road on which traffic consistently moves at a rate closer to the speed limit. Belkin's N MIMO helps traffic move at the speed limit and opens more lanes-to become the superhighway in this example. The rate of traffic flow is multiplied by the number of lanes that are opened. 2
