Atheros ROCm� Platform
Radio-On-Chip for Mobile (ROCm) Products

The AR6000 family consists of WLAN solutions based on the Atheros
ROCm platform for high-performance mobile and embedded wireless
products. 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

AR6101G Technology Overview

The Atheros AR6101G 802.11b/g single-chip solution is the first Voice-Over-Wi-Fi design in Atheros’ Radio-on-Chip for Mobile (ROCm) wireless IP platform. With this latest solution, Atheros is building on its history of innovation and success in developing custom-built,
low-cost mobile communications products. The Atheros AR6101family of single-chip solutions integrates multiple complex functions onto a single chip: computing, DSP, memory, power management, keypad, audio and display interfaces, in addition to mixed-signal and RF.

The Atheros ROCm wireless IP platform offers a complete solution, including the user interface, in an energy and memory-efficient package. With the highest level of systems integration, the AR6101G total component count is reduced by approximately 50 percent versus competitive designs, dramatically lowering the total bill-of-materials
