Scanning Variables
Additional system performance adjustments can be made with the following group of variables.
LISTENDECAY 0–0xFFFF (Optional)—Specifies the rate at which the
listen interval grows.
Default: 2
Used only in INFRASTRUCTURE mode
when POWERSAVE mode is PSP or
FASTPSP.
Listen interval begins at FASTLISTENTIME
and eventually decays to LISTENTIME.
FASTLISTENDELAY 0–0xFFFF (Optional)—Specifies the time to delay
immediately after a transmission before
beginning at FASTLISTENTIME.
Default: 200 Kusec (200ms)
Used only in INFRASTRUCTURE mode
when POWERSAVE mode is PSP or
FASTPSP.
