Atheros ROCm® Platform Radio-On-Chip for Mobile (ROCm) Products Introducing the Atheros ROCm platform of high-performance wireless solutions for mobile   and embedded devices. The Atheros ROCm platform gives customers unsurpassed ability to: Build the most power efficient devices Design for smallest form factor applications Achieve the most cost effective designs Greater integration of functionality Low-cost chip solution Deliver Atheros-class performance in a wide array of mobile devices AR6001XL Technology Overview The AR6001XL 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 upfront 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 AR6001XL is designed from the ground up to be a robust, space and energy-efficient 802.11 solution to bring true broadband access capability to a range of mobile devices.
