Introduction

Revolutionary N Wireless Technology with MIMO (N MIMO)

Your Belkin N Wireless 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.

Placement of your N Wireless 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.

section

Introduction

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.

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).

Introduction

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.
