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

-

P

roductivity 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.

Wireless Basics

Standards-Based Technology

The DI-624S Wireless 108G Storage 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

(

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-624S 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.
