The WLAN adapter supports the Continuously
Aware (CAM) and Power Save Polling (PSP) power-
management modes. CAM requires the radio to remain
on. Intel does not recommend CAM for battery
powered devices.
PSP mode allows the MU to conserve power by
suspending communication while still associated with
an AP . The AP saves data for transmission to the MU
when it wakes at given intervals. When the adapter
wakes to check for data, it switches back into CAM
until it is ready suspend communications again.
The PSP performance index, which varies from 1 to 5,
allows users to specify how often the MU wakes up to
check for data. PSP performance index 1 provides the
quickest response time (shortest sleep interval), while
PSP performance index 5 provides efficient power
consumption (longest sleep interval).
Use the Intel Network Control Panel Applet (NCPA) or
the Intel WLAN Monitor utility to manually set the PSP
performance index.
