Introduction

Revolutionary 108Mbps Wireless Pre-N Technology

with MIMO

Your Belkin Wireless Pre-N Router uses a new smart antenna

technology called Multiple Input Multiple Output (MIMO). MIMO is a

smart antenna technique that increases speed, range, reliability, and

spectral efficiency for wireless networking systems.

MIMO technology will be used for 802.11n, a standard for

next-generation 802.11 products that boosts throughput to 100Mbps.

The element that makes Belkin’s Pre-N MIMO technology different

from a conventional radio is the use of three 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 smart antenna radio (MIMO), on the other

hand, uses three antennas. This design helps combat distortion

and interference. Belkin’s Pre-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.

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 Pre-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.

During the 1990s, Stanford University researchers Greg Raleigh and

V.K. Jones showed that a characteristic of radio transmission called

multipath, which had previously been considered an impairment to

radio transmission, is actually a gift of nature. Multipath occurs when

signals sent from a transmitter reflect off objects in the environment

and take multiple paths to the receiver. The researchers showed that

multipath can be exploited to multiplicatively increase the capacity of

a radio system.

If each multipath route could be treated as a separate channel, it

would be as if each route were a separate virtual wire. A channel with

multipath then would be like a bundle of virtual wires.

section

Introduction

To exploit the benefits the virtual wires offer, MIMO uses multiple,

spatially separated antennas. MIMO encodes a high-speed data

stream across multiple antennas. Each antenna carries a separate,

lower-speed stream. Multipath virtual wires are utilized to send the

lower-speed streams simultaneously.

Wireless is not as well-behaved as a bundle of wires. Each signal

transmitted in a multipath environment travels multiple routes. This

makes a wireless system act like a bundle of wires with a great deal of

leakage between them, causing transmitted signals to jumble together.

The MIMO receiver uses mathematical algorithms to unravel and

recover the transmitted signals.

Introduction

Placement of your Wireless Pre-N Router

Important Factors for Placement and Setup

Your wireless connection will be stronger the closer your computer is

to your Router (or Access Point). 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 (or Access

Point) and connected devices increases. This may or may not be

noticeable to you. As you move further from your Router (or Access

Point), 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 (or Access Point)

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. Wireless Router or Access Point Placement

Place your Router (or Access Point), 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 (or Access Point’s) networking

antennas are parallel to each other, and are positioned

vertically (toward the ceiling). If your Router (or Access Point)

itself is positioned vertically, point the antennas as much as

possible in an upward direction.

• In multistory homes, place the Router (or Access Point) on a

floor that is as close to the center of the home as possible.

This may mean placing the Router (or Access Point) on an

upper floor.

section

Introduction

• Try not to place the Router (or Access Point) near a cordless

2.4GHz phone.

2. Avoid Obstacles and Interference

Avoid placing your Router (or Access Point) 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 or Access Point)

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 Routers (or access

points) 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 (or Access Point) 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

Introduction

are available (see your wireless adapter’s user manual), and move

your Router (or Access Point) 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 (or Access Point). Should you need to

cover an even wider area, we suggest the Belkin Wireless Range

Extender/Access Point.

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 which require a username 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.
