Wireless Basics

Wireless Basics

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 WLAN is a cellular 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 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.

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 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.

Scalability

– 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 larger infrastructure

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

of wireless devices deployed.

Inexpensive Solution

- Wireless network devices are as competitively priced as

conventional Ethernet network devices.

Installation Considerations

The D-Link DI-624MSuper G MIMO Wireless Router 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:

1

Keep the number of walls and ceilings between the DI-624M and other network

devices

to a minimum - each wall or ceiling can reduce your D-Link wireless

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

devices so that the

number of walls or ceilings is minimized.

2

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.

3

Building Materials can impede the wireless signal - a solid metal door or aluminum

studs may have a negative effect on range. Try to position wireless devices and

computers with wireless adapters so that the signal passes through drywall or

open doorways and not other materials.

4

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

devices or appliances that generate extreme RF noise.

Standards-Based Technology

The DI-624M Super G MIMO Wireless Router 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

(

O

rthogonal

F

requency

D

ivision

M

ultiplexing) 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 DI-624M 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 of up to 11Mbps in the 2.4GHz range.
