Revolutionary N1 Wireless Technology with MIMO (N1 MIMO)
Your Belkin Vision wireless 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 technology, 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 technology is the use of
aggregation as specified in the draft 802.11n standard. By shortening the
space between packets and combining multiple smaller packets into one
larger packet, Belkin’s N1 MIMO technology 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 technology 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.
Placement of your N1 Vision
Important Factors for Placement and Setup
Your wireless connection will be stronger the closer your computer is
to your N1 Vision. Typical indoor operating range for wireless devices
is between 100 and 200 feet.
In the same way, your wireless connection and performance will degrade
somewhat as the distance between your N1 Vision and connected devices
increases. This may or may not be noticeable to you. As you move further
from your N1 Vision, connection speed may decrease. Factors that can
weaken signals simply by getting in the way of your network’s radio waves
are metal appliances or obstructions, and walls.
