Wireless Basics 

(continued)

Standards-Based Technology

The DWL-G650 Wireless Cardbus Adapter utilizes the 

802.11b

 and the 

802.11g

 standards.

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-

G650 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.

The DWL-G650 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.
