Atheros Communications Inc. has introduced AR5005UG and AR5005UX featuring a completely integrated USB 2.0 interface. Using these new chipsets, WLAN equipment manufacturers can deliver high-performance 802.11g and 802.11a/g wireless connectivity with Atheros' Super G and Super AG adaptive bandwidth technology to any device with a USB port.

The company is also introducing small-form-factor reference designs based on the AR5005UG and AR5005UX. These designs measure only 2.57-inches by 0.96-inches and substantially reduce the number of discrete components required for implementation.

Like Atheros' existing WLAN solutions, the AR5005UG and AR5005UX support the latest WLAN security standards in hardware, without performance reduction. These hardware-supported standards include Wi-Fi Protected Access (WPA and WPA2) and 802.11i enhanced security using advanced encryption standard (AES). The AR5005UG and AR5005UX also support Cisco Compatible Extensions (CCX).

To facilitate the convergence of voice, video, and data communications on wireless networks, the AR5005UG and AR5005UX support the wireless media extensions (WME) QoS capabilities defined in the IEEE 802.11e draft standard. For even greater performance, these chips feature Atheros' Super G and Super AG technology, utilizing adaptive bandwidth technology to deliver over 60 Mbps of performance-on-demand throughput based on channel availability. The chips also support Atheros eXtended Range (XR) operation, which enables connections at greater distances from the access point where signals are otherwise too weak to connect.
