AIRFORCE ONE™ SINGLE-CHIP 802.11 REFERENCE DESIGN
SUMMARY OF BENEFITS
FEATURES
• Third-generation single-chip 54g™ with advanced DSP,
• DSP architecture reduces the power required to transmit data by 30%.
designed to increase receive sensitivity and extend range up to
50%. (Replaces BCM4306 54g MAC/Baseband and BCM2050
2.4-GHz radio.)
• Low power consumption improves battery life of Wi-Fi devices,
including handheld devices and consumer electronics.
• IEEE 802.11a/g CMOS MAC/Baseband with integrated 2.4GHz Direct Conversion Radio
• Simply add 5-GHz 802.11a radio BCM2060 for two-chip a/g
solution
• Programmable MAC with advanced DMA architecture and
32-bit bus interface
• Includes BroadRange™ signal processing for industry-leading
receive sensitivity and extended range:
• –74 dBm at 54 Mbps
• –76 dBm with external LNA
• Meets PCI Power Management Interface version 1.1 (ACPI).
• Designed for low CPU usage to ensure CPU resources are available for
handheld applications.
• Dynamic power management under driver control.
AIRFORCE FEATURES SET
• SmartRadio™: Continuous calibration reduces test time and
improves manufacturability.
• Xpress™ Technology: Standards-based frame bursting improves
overall network efficiency.
• Highly integrated chipset provides low cost, low power, and
small footprint for integration in a broad range of devices
• WHQL-certified drivers for Windows® XP, Windows® Me,
Windows ® 2000, Windows ® 98SE, and Windows ® 98
operating systems, portable to Linux® and Windows® CE
• Support for Bluetooth™ Coexistence Algorithm
• Flexible support for a variety of system bus interfaces
including: PCI, Mini PCI, CardBus, PCMCIA/Compact
Flash, and SDIO (4-wire, 1-wire, and SPI)
• 125 High Speed Mode™: Standards-plus performance enhancement
delivers best real-world performance when both client and AP
support High Speed Mode.
• BroadRange Technology: Standards-compliant feature increases
receive sensitivity to improve range at the higher data rates.
• Security:
• WPA- and WPA2-CERTIFIED for powerful encryption and
authentication
• AES in hardware for faster data encryption and 802.11i compatibility
