section Introduction Revolutionary N1 Wireless Technology with MIMO (N1 MIMO) 1 Your Belkin N1 Wireless Modem Router uses a new smart-antenna technology called Multiple Input Multiple Output (MIMO). N1 MIMO complies with the IEEE draft 802.11n specification. It increases 2 speed, range, reliability, and spectral efficiency for wireless networking systems. 3 The element that makes Belkin's N1 MIMO technology different from a conventional radio is the use of multiple antennas and two 4 simultaneous data streams to deliver wireless transfers around your home or office. A conventional radio uses one antenna to transmit a data stream. Belkin's N1 MIMO, on the other hand, uses three 5 antennas. This design helps combat distortion and interference. Belkin's N1 MIMO is multidimensional. It builds on one-dimensional 6 smart-antenna technology by simultaneously transmitting two data streams through the same channel, which increases wireless capacity. 7 Another element that enhances Belkin's N1 MIMO is the use of aggregation as specified in the draft 802.11n specification. 8 By shortening the space between packets and combining multiple smaller packets into one larger packet, Belkin's N1 MIMO can 9 transmit more data through available bandwidth. Think of conventional radio transmission as a two-lane highway. The 10 speed limit governs the maximum allowable flow of traffic through that lane. Compared with conventional radios, one-dimensional smart 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 N1 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.
