Wireless Solutions
Historical or old buildings, asbestos installations, and open areas where
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-wire environments
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 provides flexibility.

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 highStrictly 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.
