DWL-520+

Wireless LAN PCI Card with 22Mbps enhanced network
speed and detachable antenna.

2.4GHz Enhanced Performance Wireless LAN PCI Card

The D-Link AirPlus DWL-520+ is an enhanced speed wireless network PCI card desktop PCs. This card connects you to a

2.4GHz wireless LAN, giving you fast, secured mobile access to the network. It provides enhanced transmission speeds at up
to 22Mbps, industry standard interoperability, strong 256-bit data security and ease of use for desktop PC users
requiring fast, secure wireless network connection.

Enhanced Speed Transmission

At 22 Megabits per second, the DWL-520+ delivers high
data transfer rate within the industry standard. This speed is
double the 11Mbps normally found among IEEE 802.11b

2.4GHz wireless LAN devices.

Industry-standard Interoperability

With both WiFi certification compatibility and IEEE

802.11b wireless LAN industry standard compliance, the
DWL-520+ adapter provides you with excellent network
interoperability.

Network Security

Security is an issue when data is transmitted without the
wires. In the air, transmitted data can be easily intercepted
if not well protected by a security scheme. The DWL-520+
provides the necessary security, using the enhanced
64/128/256-bit industry-standard WEP (Wired Equivalent

TM

Privacy) encryption protocol. Data privacy mechanism is
based on a shared key algorithm, as described in the wireless
LAN standard.

Easy Installation

TM

With PCI plug-and-play installation, the DWL-520+ can be
easily installed into a desktop PC to provide connectivity
directly to another 802.11b wireless enabled device (ad-hoc
mode) or through an 802.11b Access Point (infra-structure
mode).

Detachable Antenna

The DWL-520+ is equipped with an SMA reverse
detachable dipole antenna with an effective range of 100
meters indoors, or 400 meters outdoors. Where a longer
range is required, you can easily remove this antenna and
replace it with a higher Gain antenna.
