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.
Under many circumstances, it may be desirable for mobile network devices
to link to a conventional Ethernet LAN in order to use servers, printers or an
Internet connection supplied through the wired LAN. A Wireless Access
Point (AP) is a device used to provide this link.
People use wireless LAN technology for many different purposes:
- 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.
– WLANs (Wireless Local Area Networks) are

easy to set up, manage, change and relocate. Networks that frequently
change, both physically and logically, can benefit from WLANs ease of
implementation. WLANs can operate in locations where installation of wiring
may be impractical.

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 full infrastructure networks
of thousands of users that allow roaming over a broad area.

Wireless Basics
The DWL-6000AP is compatible with the D-Link AirPro 802.11a family of
products, which include:
♦
5GHz Wireless Cardbus Adapters used with laptop computers
(D-Link DWL-A650)
♦
5GHz Wireless PCI Adapters used with desktop computers
(D-Link DWL-A520)
The DWL-6000AP is also compatible with the D-Link AirPlus 802.11b Wireless
Family of LAN products, which include:
♦ Enhanced 2.4GHz Wireless Cardbus Adapters used with laptop
computers (D-Link DWL-650+)
♦ Enhanced 2.4GHz Wireless PCI cards used with desktop computers
(D-Link DWL-520+)
Standards-Based Technology
The versatile DWL-6000AP Multimode Wireless Access Point integrates
both 802.11a and 802.11b standards into a single unit.
The IEEE 802.11a standard designates that devices operate at an optimal
data rate of 54 Mbps (72 Mbps in proprietary Turbo mode.) This means 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
(Orthogonal Frequency Division Multiplexing) 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.
D-Link AirPro products will automatically sense the best possible connection
speed to ensure the greatest speed and range possible.
Based on the IEEE 802.11b standard, the DWL-6000AP is also
interoperable with existing compatible 2.4GHz wireless technology with data
transfer speeds of up to 22Mbps ( with D-Link AirPlus Family of Wireless
devices,) as well as standard 802.11b technology ( with D-Link Air Family of
Wireless devices), with speeds of up to 11Mbps.
