Revolutionary N+ Wireless Technology with MIMo (N MIMo)
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 .
