The Power Management tab allows you to enable/disable Power Save mode and to
configure Power Save mode parameters.
Power Save mode is intended for laptops and hand-held computers, in order to
conserve battery energy. When Power Save mode is enabled, the unit "sleeps" most
of the time and "wakes up" occasionally to transmit to and receive from the Access
Point. This will extend the battery life span of a laptop with the PCMCIA Adapter
installed.
Expect a degradation in performance of the entire cell, even if only the
Access Point and one station are set to Power Save mode.
The Power Management tab includes the following parameters:
• Power Management Mode — Enable Power Save mode by clicking the
Powersave option; disable by clicking the Normal option (default).
• Listen Interval Settings — Specifies how often the station is to "wake up" in
order to transmit or receive data (unicast packets). This parameter enables
performance optimization on a per-station basis. In contrast, the DTIM period
(that is, set in the Access Point only) defines the time period for all stations in
the cell to "wake up" in order to receive broadcasts.
If the Power Save mode is enabled on one of the WLAN's PCMCIA
Adapter stations, you must also enable the Power Save mode on the
Access Point through HyperTerminal.
