D-Link DWL-G122 Technical Specifications

802.11g Wireless LAN USB Adapter

The DWL-G122 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-G122 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-G122 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.

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-G122 and

other 802.11g standard devices can be gradually added to

your network, while the rest of your older network remains

perfectly connected.

Network Security

The DWL-G122 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-G122 is equipped with a fast USB 2.0 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.

With USB hot swap and plug-and-play capabilities, the

DWL-G122 provides you with fast and easy connectivity to

wireless devices and users, no matter if they use the

802.11b or the fast 802.11g standard.
