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). 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 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.

Placement of your N Wireless Modem Router
Important Factors for Placement and Setup
Your wireless connection will be stronger the closer your computer is
to your Router. 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 Router and connected devices
increases. This may or may not be noticeable to you. As you move further
from your Router, 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.
If you have concerns about your network’s performance that might
be related to range or obstruction factors, try moving the computer
to a position between five and 10 feet from the Router in order to see
if distance is the problem. If difficulties persist even at close range,
please contact Belkin Technical Support.
Note: While some of the items listed below can affect network
performance, they will not prohibit your wireless network from
functioning; if you are concerned that your network is not operating at
its maximum effectiveness, this checklist may help.
1. Router Placement
Place your Router, the central connection point of your
network, as close as possible to the center of your wireless
network devices.
To achieve the best wireless network coverage for your “wireless
clients” (i.e., computers enabled by Belkin Wireless Notebook
Network Cards, Wireless Desktop Network Cards, and Wireless
USB Adapters):
• Ensure that your Router’s networking antennas are parallel
to each other, and are positioned vertically (toward the
ceiling). If your Router itself is positioned vertically, point the
antennas as much as possible in an upward direction.
• In multistory homes, place the Router on a floor that is as
close to the center of the home as possible. This may mean
placing the Router on an upper floor.
• Try not to place the Router near a cordless 2.4GHz phone.

Introduction

2. Avoid Obstacles and Interference
Avoid placing your Router near devices that may emit radio
“noise,” such as microwave ovens. Dense objects that can inhibit
wireless communication include:
• Refrigerators
• Washers and/or dryers
• Metal cabinets
• Large aquariums
• Metallic-based, UV-tinted windows
If your wireless signal seems weak in some spots, make sure that
objects such as these are not blocking the signal’s path (between
your computers and Router).
3. Cordless Phones
If the performance of your wireless network is impaired after
attending to the above issues, and you have a cordless phone:
• Try moving cordless phones away from your Router and your
wireless-enabled computers.
• Unplug and remove the battery from any cordless phone
that operates on the 2.4GHz band (check manufacturer’s
information). If this fixes the problem, your phone may
be interfering.
• If your phone supports channel selection, change the channel
on the phone to the farthest channel from your wireless
network. For example, change the phone to channel 1 and
move your Router to channel 11. See your phone’s user
manual for detailed instructions.
• If necessary, consider switching to a 900MHz or 5GHz
cordless phone.

4. Choose the “Quietest” Channel for your Wireless Network
In locations where homes or offices are close together, such as
apartment buildings or office complexes, there may be wireless
networks nearby that can conflict with yours.
Use the Site Survey capabilities found in the Wireless Utility of
your wireless adapter to locate any other wireless networks that
are available (see your wireless adapter’s user manual), and move
your Router and computers to a channel as far away from other
networks as possible.
• Experiment with more than one of the available channels, in
order to find the clearest connection and avoid interference
from neighboring cordless phones or other wireless devices.
• For Belkin wireless networking products, use the detailed Site
Survey and wireless channel information included with your
wireless network card. See your network card’s user guide for
more information.
These guidelines should allow you to cover the maximum
possible area with your Router. Should you need to cover an
even wider area, we suggest the Belkin Wireless Range
Extender/Access Point.

Introduction

5. Secure Connections, VPNs, and AOL
Secure connections typically require a user name and
password, and are used where security is important. Secure
connections include:
• Virtual Private Network (VPN) connections, often used to connect
remotely to an office network
• The “Bring Your Own Access” program from America Online (AOL),
which lets you use AOL through broadband provided by another
cable or DSL service
• Most online banking websites
• Many commercial websites that require a user name and password to
access your account
Secure connections can be interrupted by a computer’s power
management setting, which causes it to “go to sleep.” The simplest
solution to avoid this is to simply reconnect by rerunning the VPN or
AOL software, or by re-logging into the secure website.
A second alternative is to change your computer’s power management
settings so it does not go to sleep; however, this may not be
appropriate for portable computers. To change your power management
setting under Windows, see the “Power Options” item in the Control
Panel.
If you continue to have difficulty with Secure Connections, VPNs, and
AOL, please review the steps above to be sure you have addressed
these issues.
