XSPAN Delivers the Wireless Triple Play
The Atheros AR5008 chipsets are the company highest performance wireless LAN solutions to date. The family of products leverages all of the mandatory technical elements contained in the draft 802.11n specification, as well as several optional features, to deliver the ultimate wireless triple play experience for video, voice and data transmission throughout a home or office.
Video: With real world throughput levels up to 180 Mbps, new wireless routers and gateways featuring XSPAN with Signal-Sustain 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. Atheros SST increases the total transmit power and spatial redundancy, ensuring dropout-free coverage.
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.
