The D-Link Wireless N Dualband USB (Universal Serial Bus) Mini Adapter is an 802.11n (draft 2.0) client device designed for users looking to get a reliable wireless connection that can also handle High-Definition (HD) video streaming throughout the house. This is best achieved by using the DWA-160 together with a draft 802.11n quadband router such as the D-Link DIR-855. The DWA-160 supports Wireless N signals in either the 2.4 or 5 GHz frequency range. This means that you can check e-mail & browse the Internet using the 2.4 G Hz band while reserving the 5 G Hz band for streaming HD movies & other media. The DWA-160 is also backward compatible, which means it can be used in existing 802.11g or 802.11a networks to enable significantly enhanced reception.
