Innovative power management techniques improve battery
life by creating deep sleep state when device is in stand-by
mode.
•
•
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.
Designed for low CPU utilization to ensure CPU resources are
available for handheld applications.
A I R F O R C E F E A T U R E S E T
Innovative power management reduces power consumption by
up to 97% in standby mode, providing greatly extended battery
life for mobile devices.
