•
CERTIFIED™ to ensure complete compatibility with 802.11b
solutions and interoperability with over 800 products tested by the
Wi-Fi alliance.
Low-power consumption with a comprehensive power
management technique. Optimized for new, low-power mobile
processors, the BCM94306M consumes up to 75 percent less
power than competing technologies for extended notebook battery
life.
Maximum performance speed, reach, and security with unique
Broadcom® features such as SmartRadio™ and Xpress™
technology. Maximizes performance in presence of BlueTooth™
and other 2.4 GHz devices.
Low cost to manufacture with standard CMOS processing,
single-sided assembly, and direct conversion radio architecture
that eliminates components. Optimized for DFM and DFT.
Fast time-to-market with production quality board reference
design package and complete suite of manufacturing test tools.
Simplified global distribution with worldwide homologated
design and single SKU that provides high performance
connectivity outside the United States.
Form factors for a PC card, miniPCI, and PCI with single-function
or multi-function capability.
802.11b/g Mini PCI Reference Design
•
•
•
integrated medium access controller (MAC) that supports
future IEEE standards, such as 802.11i Security and 802.11e QoS
for built-in future proof designs.
SmartRadio technology improves wireless LAN throughput and
range with advanced signal processing techniques. The all-CMOS
solutions are capable of self-calibrating based on usage
temperature and other environmental conditions, reconfiguring
constantly for optimum performance.
OneDriver™ works with all AirForce™ 802.11a/b/54g™
solutions, simplifying the upgrade/update process for customers
and end users. Driver certification and extensive operating system
support, including WHQL certified Microsoft® Windows®
drivers, Zero configuration with Microsoft XP, and embedded
drivers for Linux® and VxWorks®.
Comprehensive security portfolio including Cisco Compatible
Extensions (CCX), Wi-Fi Protected Access (WPA) CERTIFIED,
built-in hardware support for Advanced Encryption Standard
(AES) protocol, Wired Equivalent Privacy (WEP) weak key
avoidance, TKIP, and 802.1x.
Xpress technology standards-based software enhancement.
Increases aggregate network performance by up to 75 percent in a
mixed 802.11g+802.11b environment. 54g™-based client devices
with Xpress technology can achieve more than six times greater
performance than 802.11b products.
