Wireless Basics

D-Link AirPro wireless products are based on industry standards to provide

easy-to-use and compatible high-speed wireless connectivity within your

home or business. Strictly adhering to IEEE 802.11a, the D-Link AirPro

wireless family of products will allow you to access the data you want, when

and where you want it. No longer will you be limited to one location or forced

to run new wiring through your home or office. You will be able to enjoy the

freedom that wireless networking delivers.

A wireless LAN (WLAN) is a cellular computer network that transmits and

receives data with radio signals instead of wires. Wireless LANs are used

increasingly in both home and office environments. Innovative ways to utilize

WLAN technology are helping people to work and communicate more

efficiently. Increased mobility and the absence of cabling and other fixed

infrastructure have proven to be beneficial for many users.

Wireless users can use the same network applications they use on an

Ethernet LAN. Wireless adapter cards used on laptop and desktop systems,

support the same protocols as Ethernet adapter cards. For most users, there

is no noticeable functional difference between a wired Ethernet desktop

computer and a wireless computer equipped with a wireless adapter other

than the added benefit of the ability to roam within the wireless-cell. Under

many circumstances, it may be desirable for mobile network devices to link

to a conventional Ethernet LAN in order to use servers, printers or an

Internet connection supplied through the wired LAN. A Wireless Access

Point (AP) is a device used to provide this link.

People use wireless LAN technology for many different purposes.

Mobility - Productivity increases when people have access to data in any

location within the operating range of the WLAN. Ad-hoc management

decisions based on real-time information can significantly improve worker

efficiency.

Low Implementation Costs - WLANs are easy to set up, manage, change

and relocate. Networks that frequently change, both physically and logically,

can benefit from WLANs ease of implementation. WLANs can operate in

locations where installation of wiring may be impractical. Furthermore, IEEE

standardization mandates interoperability of all WLAN devices that conform

to the 802.11a set of standards.

Installation Speed and Simplicity - Installing a wireless LAN system can

be fast and easy and can eliminate the need to pull cable through walls and

ceilings.

Wireless Basics (continued)

Installation Flexibility - Wireless technology allows the network to go where

wires cannot go.

Reduced Cost-of-Ownership - While the initial investment required for

wireless LAN hardware might be higher than the cost of wired LAN hardware,

overall installation expenses and life-cycle costs will be significantly lower.

Long-term cost benefits are greatest in dynamic environments requiring

frequent moves, adds, and changes.

Scalability - Wireless LAN systems can be configured in a variety of

topologies to meet the needs of specific applications and installations.

Configurations are easily changed and range from peer-to-peer networks

suitable for a small number of users to full infrastructure networks of

thousands of users that allow roaming over a broad area.

D-Link AirPro Wireless LAN products include:

 802.11a 5GHz Wireless Cardbus Adapters used with laptop

computers (DWL-A650)

 802.11a 5GHz Wireless PCI cards used with desktop computers

(DWL-A520)

 802.11a 5GHz Wireless Access Points (DWL-5000AP)

Standards - Based Technology

The IEEE 802.11a standard designates that devices operate at an optimal

data rate of 54 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 transmitting high-speed

digital data over a radio wave utilizing OFDM (Orthogonal Frequency

Division Multiplexing) technology. OFDM works by splitting the radio signal

into multiple smaller sub-signals that are then transmitted simultaneously at

different frequencies to the receiver. OFDM reduces the amount of

crosstalk (interference) in signal transmissions. D-Link AirPro 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 900 feet (~300 meters), D-Link AirPro DWL-5000AP

lets you access your network with your laptop computer from virtually

anywhere you want. Keep in mind, however, that the number and thickness

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

may limit range. 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 between the Access Point and

your receiving device to a minimum - Each wall or ceiling can reduce

your D-Link AirPro Wireless product’s range from 3-90 feet (1-30 meters.)

For some businesses or for a large residential home deployment, it may

be beneficial to have more than one access point with overlapping

coverage.

2. Be aware of the direct line between Access Points and computers with

wireless adapters - A wall that is 1.5 feet thick (.5 meters), at a 45-

degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree

angle it looks over 42 feet (14 meters) thick! Try to make sure that the

Access Points 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,

and computers with wireless adapters 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 or 1-2 meters) from electrical

devices or appliances that generate extreme RF noise.

Wireless Basics (continued)

For the average residence, 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 computers with wireless adapters 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.

Using radio frequency (RF) technology, WLANs (Wireless Local Area

Networks) transmit and receive data over the air, minimizing the need for

wired connections. Thus, WLANs combine data connectivity with user

mobility, and, through simplified configuration, enable movable LANs.

Getting Started

To begin, select the type of wireless network you will be building.

We will discuss the following types of networks in this section:

1. A Home Internet Network

with A Residential Gateway/Router

2. A Home Internet Network with Multiple IP Addresses

Please select, from the two types of networks described above, the type of

network that is appropriate for your needs. Please follow the instructions in

the corresponding section that follows.

1. A Home Internet Network with A Residential Gateway/Router

(Network administrators with Dynamic IPs can also follow these instructions.)

If you have two or more computers (laptops or desktops) and want to share

files, printers, and Internet access using a DHCP-capable Residential

Gateway/Router – or - if you want to connect to an Ethernet network that

uses Dynamic (DHCP) IP addresses, then follow the instructions on the next

page. When it is complete, your network may look similar to this:

DHCP stands for

Dynamic Host

Configuration

Protocol. It is a

rotocol for

assigning dynamic

IP addresses

“automatically.”

With a DHCP-

capable gateway,

there is no need to

manually assign

an IP address.
