Wireless Basics 

(continued)

Standards-Based Technology

The  

DWA-520

 Wireless PCI Adapter 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 54 Mbps 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 D-Link DWL-

G520 will automatically sense the best possible connection speed to ensure the greatest
speed and range possible.

802.11g offers the most advanced network security features available today, including:

WPA

/WPA2

,802.1x,TKIP,AES and Pre-Shared Key mode

.

 

These security feature

are 

explained in more detail in the

 Introduction 

and the

 Features 

section of this manual.

The 

DWA-520

 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 up to 11Mbps in the 2.4GHz range.

The 

DWA-520

 is compatible with 802.11g and 802.11b wireless products, which include
