Atheros XSPAN® Technology
Expanding performance. Expanding possibilities.

The Atheros AR5008 chipsets are Atheros’ highest performance
wireless LAN solutions to date. AR5008 products are compliant to the
draft 802.11n specification, to deliver the ultimate wireless triple
play experience for video, voice and data transmission throughout the
home or office.

Video: With real world throughput levels up to 300 Mbps PHY rate, new wireless routers and gateways featuring Atheros XSPAN technology will readily accommodate multiple high-definition (HD) streams on a single home network.

Voice: Single-antenna wireless voice handsets and legacy devices networked to Atheros-based access points achieve range and robustness from Atheros’ triple transmitter architecture.

Data: The array of data applications ranging from simple network computing to transmission of large data, music or image files is enhanced through the high bandwidth provided by XSPAN products.

Product Overview

With the introduction of new bandwidth intensive applications and growth of Gigabit Ethernet ports, there is increasing demand for wireless LAN throughput. Featuring the Atheros AR5008E-3NX, our first 2.4/5 GHz IEEE draft 802.11n WLAN solution. The Atheros
AR5008E-3NX dramatically increases the overall throughput of the wireless LAN by supporting link rates as high as 300 Mbps - an improvement of nearly six times the throughput of standard 802.11a or 802.11g.

The AR5008E-3NX is interoperable with standard 802.11a, 802.11b and 802.11g devices and fully supports industry standards compliant security and Quality of Service (QoS). Full reference design support is available.
