D-Link DWL-G120 Technical Specifications

802.11g Wireless LAN USB Adapter
The DWL-G120 is a high-performance 802.11g wireless LAN USB adapter that connects your computer to a high-speed wireless
LAN. This adapter simply plugs to your computer through a fast USB 2.0 interface to provide up to 54Mbps wireless speed. With
industry standard interoperability, backward compatibility with 802.11b devices and plug-and-play installation, this adapter is
an ideal solution for notebook and laptop PC users needing fast and standard mobile network connection.
Up to 54Mbps Transmission Speed
The DWL-G120 provides speeds of up to 54Mbps when used
with other 802.11g wireless devices. This compares favorably
with 802.11b adapters that offer only 11Mbps transmission.
Compatible With 802.11b
Like the 802.11b devices, the DWL-G120 uses a single
2.4GHz wireless frequency, eliminating the complexity of
dualband networking. 802.11g's compatibility with existing
wireless LAN standards means that you do not need to
change your entire network to maintain connectivity. You
may sacrifice some of 802.11g's speed when you mix
802.11b with 802.11g devices, but you will not lose the
ability to communicate.
Easy Migration to Higher Bandwidth
By maintaining compatibility with your existing wireless
network equipment, this adapter lets you upgrade to a higher
speed at the pace you want. The DWL-G120 and other
802.11g standard devices can be gradually added to your
network, while the rest of your older network remains
perfectly connected.
Adjustable Antenna
With its unique flip-up, adjustable antenna design, and the
long USB cable that is included with the network adapter,
you can position the DWL-G120 adapter virtually anywhere
on a flat surface to achieve the best available wireless signal
reception.

Network Security
The DWL-G120 supports Wi-Fi Protected Access (WPA) to
provide the necessary security protocols and tools, so you can
communicate with other wireless users confidentially, access
sensitive information or send data that is dynamically
encrypted as it's sent. WPA allows authorization and
identification of users based on a secret key that changes
automatically at a regular interval. Used in conjunction with a
RADIUS server, WPA uses TKIP (Temporal Key Integrity
Protocol) to change the temporal key every 10,000 packets.
This insures much greater security than the standard WEP
security, which requires the keys to be changed manually.
Fast USB 2.0 Interface
The DWL-G120 is equipped with a fast USB 2.0 mini port
and a USB cable that connects to your computer, providing
data throughput at up to 480Mbps between the network
adapter and the host computer. That is about 40 times faster
than the earlier USB 1.1 specification, allowing you to take
advantage of the high 54Mbps wireless speed that this
adapter provides.
Portable Pocket-sized
With its antenna folded up, the DWL-G120 is an attractive,
portable wireless device. It can fit into your pocket or
carrying case, allowing you to easily carry it around.
