Wireless Settings - 802.11g or 802.11a - Advanced
Contention Slot
Select “Short” or “Long”. If “Short” is selected, the communication speed 
may be improved, but connection may not be possible to wireless 
devices that do not support short slot time. Make the same setting for 
the connected wireless devices. This option is not available in 802.11a.
Preamble Type
Select “Long” or “Short”. If “Short” is selected, the communication speed 
may be improved, but connection may not be possible to wireless 
devices that do not support short preamble. Make the same setting for 
the connected wireless devices. This option is not available in 802.11a.
Guard Interval
Select the encoding format during frame sending. “Long GI” arranges the 
encoding with a certain amount of time or space to prevent interference. 
“Short GI” shortens this interval to send more information.
Aggregation
To improve the transmission rate, multiple transmission frames are 
aggregated into one frame. The AirStation supports AMSDU and AMPDU.
802.11g Protection
If enabled, communication with 11g devices can be given priority even 
in environments where 11g and 11b wireless LAN devices coexist. This 
option is not available in 802.11a.
802.11n Protection
If enabled, collisions and other adverse effects on performance can be 
reduced even in environments where devices using previous bands (11a, 
11b, 11g) coexist.
DTIM Period
This interval is how often the AirStation sends power management 
information to wireless devices. Larger values may reduce power 
consumption, but might cause slower responses.
This setting is ignored if the power management setting in the wireless 
device (computer) is disabled.
