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
Ethernetadaptercards.
D-Link wireless products are based on industry standards to provide easy-to-use and
compatiblehigh-speedwirelessconnectivity withinyourhome,businessorpublicaccess
wirelessnetworks. D-Link wireless products will allow you access to the data you want,

office environments, and public areas such as airports, coffee shops and universities.

more efficiently. Increased mobility and the absence of cabling and other fixed
infrastructurehaveproven to bebeneficial for manyusers.
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
informationcan 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
technologyallows the network to go where wirescannot go- even outside the home or
office.
Inexpensive Solution - Wireless network devices are as competitively priced as
conventional Ethernet network devices. The DWL-G820 saves money by providing
multi-functionality, configurable in one of four different modes.
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
fromPeer-to-Peernetworkssuitable for a smallnumberof users to largerInfrastructure
networksto accommodate hundreds or thousands of users, depending on the number
ofwirelessdevices deployed.
