Wireless Solutions

11Mbps Wireless LAN products offer a fast, reliable, cost-effective solution for

wireless client access to the network in applications like these:

1. Remote access to corporate network information

E-mail, file transfer and terminal emulation

2. Difficult-to-wireenvironments

Historical or old buildings, asbestos installations, and open areas where

wiring is difficult to deploy

3. Frequently changing environments

Retailers, manufacturers and those who frequently rearrange the workplace

and change locations

4. Temporary LANs for special projects or peak time

Trade shows, exhibitions and construction sites may require a temporary

network. Retailers, airlines and shipping companies need additional

workstations during peak periods. Auditors may set up workgroups at

customer sites.

5. Access to database for mobile workers

Doctors, nurses, and retailers, may access their databases while maintaining

mobility in the hospital or retail stores.

6. SOHO (Small Office and Home Office) users

SOHO users can have easy and quick installation of a small computer

network.

7. High security connection

The secure wireless network is installed quickly and providesflexibility.

System Requirements

In order to use the 11Mbps Wireless LAN Compact Flash Adapter, your desktop or

laptop computer (with which you will “sync” your PDA) must be equipped with the

following:

“Microsoft Active Sync” software

Wireless Basics

Your new D-Link Air product is based on industry standards to provide easy to use

and compatible high-

speed wireless connectivity within your home or business.

Strictly adhering to IEEE 802.11b, the D-Link Air family of products will allow you

to access the data you want, when and where you want it. No longer will you be

tethered to a workstation or forced to run new wiring. You will be able to enjoy the

freedom that wireless networking delivers.

Standards Based Technology

Based on IEEE 802.11b, D-Link Air products can perform up to 11 Megabits per

second. This means you will be able to transfer large files quickly or even watch a

Movie in MPEG format over your network without noticeable delays. This

technology works by using multiple frequencies in the 2.4GHz range utilizing Direct

Sequence Spread Spectrum (DSSS) technology. D-Link Air products will

automatically sense the best possible connection speed to ensure the greatest speed

and range possible with the technology.

Installation Considerations

Designed to go up to 800 feet in an open environment, D-Link Air lets you access

your network from anywhere you want. However, keep in mind, that range is limited

by the number of walls, ceilings, or other objects that the wireless signals must pass

through. Typical ranges vary depending on the types of materials and background

RF noise in your home or business. The key to maximizing range is to follow these

basic principles:

1. Keep the number of walls and ceilings to a minimum -Each wall or ceiling can

rob your D-Link Air Wireless product of 3-90 ft. of range. Position your

Access Points, Residential Gateways, and computers so that the number of

walls or ceilings is minimized.

2. Be aware of the direct line between Access Points, Residential Gateways, and

Computers -A wall that is 1.5 feet thick, at a 45 degree angle, appears to be

almost 3 feet thick. At a 2-degree angle it looks over 42 feet thick! Try to

make sure that the Access Point and Adapters are positioned so that the

signal will travel straight through a wall or ceiling for better reception.

3. Building Materials make a difference -A solid metal door or aluminum studs

may have a negative effect on range. Try to position Access Points,

Residential Gateways, and Computers so that the signal passes through

drywall or open doorways and not other materials.

4. Make sure that the antenna is positioned for best reception by using the

software signal strength tools included with your product.

5. Keep your product away (at least 3-6 feet) from electrical devices that generate

RF noise, like microwaves, Monitors, electric motors, etc.

For the average American home, range should not be a problem. If you experience

low or no signal strength in areas of your home that you wish to access, consider

positioning the Access Point in a location directly between the Residential Gateways

and/or Computers that will be connected. Additional Access Points can be connected

to provide better coverage in rooms where the signal does not appear as strong as

desired.

Network Configuration

The 11Mbps Wireless LAN products support the same network configuration

options of the legacy Ethernet LANs as defined by IEEE 802 standard committee.

The 11Mbps Wireless LAN products can be configured as:

§Ad-Hoc for departmental or SOHO LANs

§Infrastructure for enterprise LANs

§LAN-Interconnection for point-to-point link as a campus backbone

Network Topology

Ad-Hoc Wireless Network

An Ad-Hoc wireless LAN is a group of computers, each equipped with one wireless

adapter, connected as an independent wireless LAN. Computers in a specific

Ad-Hoc wireless LAN must be configured at the same radio channel.

Ad-Hoc wireless LAN is applicable at a departmental scale for a branch or SOHO

operation.

-8-

Infrastructure Wireless Network

The 11Mbps Wireless LAN devices provide access to a wired LAN for wireless

workstations. An integrated wireless and wired LAN is called an Infrastructure

configuration. A group of wireless LAN PC users and anAccess Point construct a

Basic Service Set (BSS). Each wireless-equipped PC in this BSS can talk to any

computer in the wired LAN infrastructure via the Access Point.

Infrastructure configuration will extend the accessibility of a wireless station to the

wired LAN. Multiple Access Points will allow roaming and it will increase the

transmission range. The Access Point

is also able to forward data within its BSS.

The effective transmission range in an infrastructure LAN is doubled.
