D-Link DWL-G122 Wireless G USB Adapter
The D-Link DWL-Gg Wireless LAN USB Adapter is a high-performance g 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 b 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 D-Link DWL-G122 provides speeds of up to 54Mbps when used with other g wireless devices. This compares favourably with b adapters that offer only 11Mbps transmission. Compatible With b Like the b devices, the DWL-G122 uses a single 2.4GHz wireless frequency, eliminating the complexity of dualband networking. g'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 D-Link DWL-G122 and other g 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-FiTM 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 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
