D-Link DWL-G122 [6/45] Wireless basics

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.
