Introduction

Revolutionary N1 Wireless Technology with MIMO (N1 MIMO)

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 speed, range, reliability, and spectral efficiency for wireless networking systems.

The element that makes Belkin’s N1 MIMO technology different from a conventional radio is the use of multiple antennas and two 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 antennas. This design helps combat distortion and interference. Belkin’s N1 MIMO is multidimensional. It builds on one-dimensional smart-antenna technology by simultaneously transmitting two data streams through the same channel, which increases

wireless capacity.

Another element that enhances Belkin’s N1 MIMO is the use of 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 N1 MIMO can transmit more data through available bandwidth.

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 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.
