AIRFORCE ONE™ CHIP 802.11 REFERENCE DESIGN
POWER MANAGEMENT
KEY FEATURES
• Industry's smallest IEEE 802.11b/g solution makes wireless
•
•
•
•
•
LAN connectivity practical for pocket-sized electronic devices.
Extreme integration includes radio, baseband, MAC, and all
other radio frequency (RF) components found on a typical
wireless LAN board—making small mobile devices easier, less
expensive and faster to manufacture.
Innovative power management reduces power consumption by
up to 97% in standby mode, providing greatly extended battery
life for mobile devices.
Cost-effective architecture with single-sided, all-CMOS design
eliminates over 100 components, providing more affordable
wireless connectivity for consumer electronics.
High-performance features standard across the AirForce
product line:
• OneDriver™
• SmartRadio™
• WPA, WPA2
• Cisco® Compatible Extensions (CCX)
• AES in hardware
• WMM for advanced Quality of Service
• Xpress™ technology
• 125 High Speed Mode™
Reference designs include Secure Digital I/O, MiniPCI,
CardBus, and Compact Flash.
• Innovative power management techniques improve battery
life by creating deep sleep state when device is in stand-by
mode.
• Designed for low CPU utilization to ensure CPU resources are
available for handheld applications.
AIRFORCE FEATURE SET
• SmartRadio: Continuous calibration reduces test time and
improves manufacturability.
• Xpress Technology: Standards-based frame bursting
•
•
•
•
improves overall network efficiency.
125 High Speed Mode: Standards-plus performance
enhancement delivers best real-world performance when both
client and AP support High Speed Mode.
Security:
• WPA- and WPA2-CERTIFIED for powerful encryption and
authentication
• AES in hardware for faster data encryption and 802.11i
compatibility
• Cisco Compatible Extensions (CCX, CCX 2.0) certified
• SecureEZSetup™ for simple Wi-Fi setup and WPA security
configuration
Worldwide support: Global products supported with
worldwide homologated design.
OneDriver: Single driver across all platforms—802.11a/b/g—
simplifies driver update process and improves customer
satisfaction.
