[Introduction]
Your Belkin N Wireless Modem 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, reliability, and spectral efficiency for wireless networking systems.
The element that makes Belkin’s N 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 N
MIMO, on the other hand, uses two antennas. This design helps combat
distortion and interference. Belkin’s N 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 N 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 N 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 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.
