3. Wireless Basics

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

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

home, business or wherever a wireless network is available. Strictly adhering

to the IEEE standard, the D-Link AirPlus 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 local area network (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, and

public areas such as airports, coffee shops and universities. Innovative ways

to utilize WLAN technology are helping people to work and communicate

more efficiently. Increased mobility with the absence of cabling and other

fixed infrastructure have proven to be beneficial for many users.

Wireless users can use the same applications they use on a wired network.

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 a 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. Management decisions

based on real-time information can significantly improve worker efficiency.

Low Implementation Costs – WLANs (Wireless Local Area Networks) 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.

Installation Speed and Simplicity - Installing a wireless LAN system can

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

and ceilings.

Wireless Basics

Network Expansion - 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 Local Area Networks (WLANs) 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.

Standards - Based Technology

The IEEE standard-based technology assures that the D-Link AirPlus

Products are interoperable with existing compatible 2.4GHz wireless

technology. 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. The technology works by using multiple frequencies in the 2.4GHz

range at speeds up to 22Mbps. D-Link AirPlus products will automatically

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

range possible with the technology.

Wireless Basics

Installation Considerations

Designed to go up to 1,312 feet (400 meters) outdoors and up to 328 feet

(100 meters) indoors, the D-Link AirPlus DWL-520+ lets you access your

network with your laptop computer from virtually anywhere. Keep in mind,

however, that the number, thickness and location of walls, ceilings or other

objects that the wireless signal must pass thru may limit range. Typical

ranges vary depending on the types of materials and any background RF

(radio frequency) noise in your home or business. The key to maximizing

range is to follow these basic guidelines:

1. Keep the number of walls and ceilings between the wireless Access

Point and your receiving device (i.e., the DWL-520+) to a minimum -

Each wall or ceiling can reduce your D-Link AirPlus Wireless product’s

range from 3-90 feet (1-30 meters.) 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 (routers), and computers. 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 device’s 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 may generate extreme RF noise.

Wireless Basics

For the average home, signal range should not be an issue. 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. 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.

4. Getting Started

Right out of the box, with its default settings, the DWL-520+ will

automatically connect with other D-Link Air or AirPlus products.

For the price of a single IP Address from your Broadband Internet Service

provider you can share the Internet with all the computers on your local

network, without sacrificing speed or security, using D-Link AirPlus

networking products.

There are basically two modes of networking:

Infrastructure – using an Access Point, such as the DWL-1000AP

Ad-Hoc – directly connecting to another computer, for peer-to-peer

communication, using wireless network adapters on each computer, such

as two or more DWL-520+ wireless network PCI adapters.

On the following pages we will show you an example of an Infrastructure

Network and an Ad-Hoc Network.

An Infrastructure network contains an Access Point. The Infrastructure

Network example shown on the following page contains the following D-Link

network devices:

A wireless DHCP Router/Access Point/Print Server - D-Link Air DI-713P

A laptop computer with a wireless network adapter - D-Link AirPlus DWL-650+

A desktop computer with a wireless network adapter - D-Link AirPlus DWL-520+

A Cable modem - D-Link DCM-200

DHCP stands for Dynamic Host Configuration Protocol. It is a protocol for assigning IP

addresses “automatically.” With a DHCP-capable gateway/router, there is no need to

manuall

assi

n an IP address.
