Atheros AR6001GL Embedded 802.11b/g Solution for Mobile and Batt operated devices

AR6001GL Technology Overview
The AR6001GL allows direct connection to cellular baseband and application processors via SDIO, SPI, and memory-mapped parallel interfaces. Its on-board processing and storage capabilities allow it to be integrated with the host platform with minimal development up-front and minimal loading during runtime. With its high degree of on-chip integration, it requires minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.

Sophisticated system-level features include fast sleep/wake context switching for energy-efficient VoIP, adaptive radio biasing for low-power operation, and spur cancellation and radio co-existence features for cellular/Bluetooth/802.11 interference mitigation. The AR6001GL is designed from the ground up to be a robust, spaceand energy-efficient 802.11 solution to bring true broadband access capability to a range of mobile devices.
