Power Management Variables
The Wireless LAN Adapter power management can be adjusted with the following group of variables.
Table 3-7 Power Management Variables
Variable Value Description
POWERSAVEMODE CAM
PSP
FASTPSP
(Optional)—Establishes the operating method
the device uses to conserve electrical power.
CAM = Constant Awake Mode
PSP = Power Save Mode
FASTPSP = Fast Power Save Mode
Default: CAM
In ad hoc mode, if the POWERSAVEMODE
is PSP or FASPSP, the ATIMDURATION
variable must be a non-zero value.
CAM keeps the client adapter powered up
continuously so there is little lag in message
response time. This mode consumes the most
power but offers the highest throughput.
PSP powers the adapter on and off based on a
time algorithm. When retrieving packets, the
adapter remains in PSP mode and manages
only the amount of traffic within the time
period when it is scheduled on. When the time
expires, the adapter turns off for the required
time and then turns back on again to retrieve
more data.
FASTPSP switches between a PSP mode and
CAM, depending on network traffic. This
mode switches to CAM when retrieving a
large number of packets and switches back to
PSP after the packets have been retrieved.
MAXPOWERSAVE ON (YES)
OFF (NO)
(Optional)—Turns Maximum Power Save
mode on or off.
Default: OFF
MAXPOWERSAVE causes the access point
to buffer incoming messages for the client
adapter, which wakes up periodically and
polls the access point to see if any buffered
messages are waiting for it. The adapter can
request each message and then go back to
sleep.
MAXPOWERSAVE conserves the most
power but offers the lowest throughput. Is
recommended for devices for which power
consumption is the ultimate concern (such as
small battery-powered devices).
