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 on 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.

Standards-based Technology

The

DGL-4300 Wireless Broadband Router utilizes the new

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

(

F

requency

D

M

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 DGL-4300 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.

Installation Considerations

The D-Link DGL-4300 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:



Keep the number of walls and ceilings between the DGL-4300 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.



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 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.



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

that generate extreme RF noise.
