Wireless Basics

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.

D-Link wireless products are based on industry standards to provide easy-to-use and

compatible high-speed wireless connectivity within your home, business or public

access wireless networks. D-Link wireless products will allow you access to the data you

want, when and where you want it. You will be able to enjoy the freedom that wireless

networking brings.

A wireless local area network (WLAN) is a computer network that transmits and

receives data with radio signals instead of wires. WLANs 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 and the absence of cabling and

other ﬁxed infrastructure have proven to be beneﬁcial to many users.

People use WLAN 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 are easy to set up, manage, change and relocate.

Networks that frequently change can beneﬁt from WLANs ease of implementation.

WLANs can operate in locations where installation of wiring may be impractical.

Installation and Network Expansion - Installing a WLAN system can be fast and easy

and can eliminate the need to pull cable through walls and ceilings. Wireless technology

allows the network to go where wires cannot go - even outside the home or ofﬁce.

Inexpensive Solution - Wireless network devices are as competitively priced as

conventional Ethernet network devices.

Scalability - WLANs can be conﬁgured in a variety of ways 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 larger Infrastructure

networks to accommodate hundreds or thousands of users, depending on the number

of wireless devices deployed.

Standards-Based Technology

The DWL-G520M Wireless PCI Adapter utilizes the 802.11g standard.

The IEEE 802.11g standard is an extension of the 802.11b standard. It increases

the data rate up to 54Mbps within the 2.4GHz band, utilizing OFDM technology.

This means that in most environments, within the speciﬁed range of this device, 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. The D-Link DWL-G520M will automatically sense the best

possible connection speed to ensure the greatest speed and range possible.

802.11g offers the most advanced network security features available today, including:

WPA, 802.1x, TKIP, AES and Pre-Shared Key (PSK) mode.

The DWL-G520M is backwards compatible with 802.11b devices. This means that if

you have an existing 802.11b network, the devices in that network will be compatible

with 802.11g devices at speeds up to 11Mbps in the 2.4GHz range. Also based on the

IEEE 802.11b standard, the DWL-G520M is interoperable with existing compatible

2.4GHz wireless technology with data transfer speeds of up to 11Mbps.

Installation Considerations

The DWL-G520M lets you access your network using a wireless connection from

virtually anywhere within its operating range. Keep in mind, however, that the number,

thickness and location of walls, ceilings, or other objects that the wireless signals

must pass through, may limit the range. Typical ranges vary depending on the types of

materials and background RF (radio frequency) noise in your home or business. The

key to maximizing wireless range is to follow these basic guidelines:

Installation Considerations



 Keep your product away (at least 3-6 feet or 1-2 meters) from

electrical devices or appliances that generate RF noise.

Keep the number of walls and ceilings between the DWL-G520M

and other network devices to a minimum - each wall or ceiling can

reduce your adapter’s range from 3-90 feet (1-30 meters.) Position

your devices so that the number of walls or ceilings is minimized.

Be aware of the direct line between network devices. 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! Position devices so that the signal will travel

straight through a wall or ceiling (instead of at an angle) for better

reception.

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

studs may have a negative effect on range. Try to position access

points, wireless routers, and computers so that the signal passes

through drywall or open doorways. Materials and objects such as

glass, steel, metal, walls with insulation, water (ﬁsh tanks), mirrors,

ﬁle cabinets, brick, and concrete will degrade your wireless signal.

If you are using 2.4GHz cordless phones or X-10 (wireless products

such as ceiling fans, lights, and home security systems), your

wireless connection may degrade dramatically or drop completely.

Make sure your 2.4GHz phone base is as far away from your

wireless devices as possible. The base transmits a signal even if

the phone in not in use.

A wireless router - D-Link 108G MIMO DI-634M

Desktop computers with a D-Link 108G MIMO DWL-G520M

A cable modem - D-Link DCM-202

Getting Started

There are basically two modes of networking:

Infrastructure – using an access point or router, such as the DI-624M.

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-G520M

Wireless Network 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 or router. The Infrastructure

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

devices (your existing network may be comprised of other devices):

Infrastructure Network

Setting up a Wireless Infrastructure Network

For a typical wireless setup at home, please do the following:

You will need broadband Internet access (a cable or DSL-subscriber line

into your home or ofﬁce).

Consult with your cable or DSL provider for proper installation of the modem.

Connect the cable or DSL modem to your broadband router.

(See the Quick Installation Guide included with your router.)

Install the D-Link DWL-G520M 108G MIMO Wireless Desktop Adapter into

an available PCI slot on your desktop computer.

(See the Quick Installation Guide included with the DWL-G520M.)

5Install another D-Link DWL-G520M 108G MIMO Wireless Desktop Adapter

into an available PCI slot on your desktop computer.
