device’s wireless performance and is also power-saving for client side. If this value set
lower than 100ms, it will speed up the wireless client connection.
Preamble Type:
this option is to define the length of the sync field in an 802.11 packet.
Most modern wireless network uses shot preamble with 56 bit sync filed instead of long
preamble with 128 bit sync filed. However, some original 11b wireless network devices only
support long preamble. By default, Long Preamble is selected.
IAPP
：
Inter-Access Point Protocol is designed for the enforcement of unique association
throughout an ESS (Extended Service Set) and for secure exchange of station’s security
context between current access point (AP) and new AP during handoff period. It is enabled
by default.
Protection:
it is disabled by default.
Aggregation:
A part of the 802.11n standard. It allows sending multiple frames per single
access to the medium by combining frames together into one larger frame. It creates the
larger frame by combining smaller frames with the same physical source and destination
end points and traffic class (i.e. QoS) into one large frame with a common MAC header. It is
enabled by default.
Short GI:
short Guide Interval. It is to assure the safety of propagation delays and
reflections for the sensitive digital data.
WLAN Partition:
divides the WLAN to several parts.
20/40MHz Coexist:
enable this function will make the device select the channel with better
performance automatically. It is disabled by default.
RF Output Power:
you can select the output power of the wireless device. The default
value is 100%. It will deliver the best performance of the device.
4.6.6 Wireless WDS Settings
WDS means Wireless Distribution System. It is a protocol for connecting two access points
wirelessly. Usually, it can be used for the following application:
1. Provide bridge traffic between two LANs though the air.
2. Extend the coverage range of a WLAN.
To meet the above requirement, you must set these APs in the same channel and set MAC
address of other APs which you want to communicate with in the table and then enable the
WDS.
