The D-Link Xtreme N Dual Band USB Adaptor (DWA-160) is the latest addition to the award-winning Xtreme N product family. The DWA-160 is designed for users looking to get a reliable wireless connection that can handle High-Definition (HD) video streams throughout the house. This is achieved by using the DWA-160 together with a draft 802.11n dual band router (D-Link DIR-855 or DGL-4500 recommended). The dual band N technology in the DWA-160 supports selectable 2.4GHz or 5GHz wireless signals. This allows you to check e-mail and browse the Internet using the 2.4GHz band or stream HD movies and other media on the 5GHz band. The 5GHz wireless band is the best technology available for wirelessly streaming HD videos across your network. It achieves this by operating in a clear wireless band to help avoid interference that may slow down and limit the range of current wireless technologies like 802.11g1. The DWA-160 is also backward compatible to 802.11g, which means it can be used in existing 802.11g networks.
