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

F

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.
