Industry leading throughput
Direct conversion radio architecture uses fewer
external components and eliminates expensive external
RF filters
•
•
•
•
Best-in-class range due to advanced signal processing
and excellent receiver sensitivity
Simple 2-chip design with fully integrated VCO using
bulk CMOS process technology
Robust performance in real-world operating
environments even in the presence of other wireless
LANs, BluetoothTM devices, and microwave oven
interference
•
Low manufacturing cost due to single-sided assembly
Complete suite of manufacturing test tools
•
•
•
Lowest CPU utilization design that leaves system
resources available for other functions
•
•
•
Significantly faster testing cycle with on-chip
autocalibration that removes radio calibration from
the manufacturing test process
Extended battery life due to low-power, all-CMOS
design and low CPU utilization
Fast time-to-market with production-quality board
reference design
•
•
•
High-performance security through support for 40/128
WEP, WEP weak-key avoidance, TKIP, AES, and
802.1x
Supports PCI, mini PCI, Cardbus, PCMCIA, and
Compact Flash form factors
Seamless Microsoft® XP zero-config integration with
advanced utilities and common GUI for legacy
operating systems
•
Flexible, high-performance MAC supports IEEE-
specified security and QOS upgrades without changing
the manufacturing process
IEEE 802.11b compliant, Wi-FiTM certified and world-
wide homologated design
•
•
Advanced MAC architecture includes a 32-bit bus and
is used on next generation 54 Mbps products
•
WHQL certificated drivers for Windows® XP, Windows
2000, and Windows 98ME/SE operating systems
