Wi-Fi Multimedia 
WMM Capable 
WMM Power Save is a set of features for Wi-Fi networks that help 
conserve battery power in small devices such as phones, PDAs, and 
audio players. The certification for both access points and client 
devices uses mechanisms from the recently ratified IEEE 802.11e 
standard, and is an enhancement of legacy 802.11 power save. WMM 
Power Save helps pave the way for rapid proliferation of Wi-Fi 
technology into devices dependent on battery power. 
Select Disable or Enable to use or stop Wi-Fi Multimedia function. 
(Default setting is Enable.) 
APSD Capable 
Automatic Power Save Delivery is a more efficient power 
management method than legacy 802.11 Power Save Polling. Most 
newer 802.11 station already support a power management 
mechanism similar to APSD. APSD is very useful for a VoIP phone, 
as data rates are roughly the same in both directions. Whenever Voice 
data are sent to the Access Point, the Access Point is triggered to send 
the buffered Voice data in the other direction. After that the Voice 
over IP phone enters doze state until next Voice data have to be sent 
to the Access Point. 
Select Disable or Enable this function. (Default setting is Disable.) 
DLS Capable 
Direct Link Setup, this function will be enabled under the connection 
with AP which must support the DLS function. Direct Link Setup 
allows direct STA-to-STA frame transfer within a BSS (Basic Service 
Set). This is designed for consumer use, where STA-to-STA transfer 
is more commonly used. 
Select Disable or Enable this function. (Default setting is Disable.)
