Wireless Wmm Qos Setup - TRENDnet TEW-740APBO User Manual

TRENDnet User's Guide
wireless stations, which support power saving mode, when to wake up to receive
multicast frame. DTIM is necessary and critical in wireless environment as a
mechanism to fulfill power-saving synchronization. A DTIM interval is a count of the
number of beacon frames that must occur before the access point sends the
buffered multicast frames. For instance, if DTIM Interval is set to 3, then the Wi-Fi
clients will expect to receive a multicast frame after receiving three Beacon frame.
The higher DTIM interval will help power saving and possibly decrease wireless
throughput in multicast applications.

Fragment Threshold: The default range for the fragment threshold isf
256~2346 bytes. The default is 2346 byte. This setting is used to specify the
maximum size for a data packet before being fragmented into multiple data
packets.

RTS Threshold: RTS Threshold is in the range of 1~2347 byte. The default is
2346 byte. The main purpose of enabling RTS by changing RTS threshold is to
reduce possible collisions due to hidden wireless clients. RTS in AP will be
enabled automatically if the packet size is larger than the Threshold value. By
default, RTS is disabled in a normal environment supports non-jumbo frames.

Short Preamble: By default, it's "Enable". To Disable is to use Long 128-bit
Preamble Synchronization field. The preamble is used to signal "here is a train
of data coming" to the receiver. The short preamble provides 72-bit
Synchronization field to improve WLAN transmission efficiency with less
overhead.

IGMP Snooping – Enabling this setting identifies multicast traffic transmitted
over the access point and filter accordingly to prevent multicast flooding.

Greenfield – When enabled, restricts the access point to communicate only
with other 802.11n devices. Other pre-802.11n clients such as 802.11b/g will
be ignored.

To achieve optimal wireless performance, it is necessary to tweak advance setting per
requirements properly, not necessary higher the better or lower.
The administrator can change the RTS threshold and fragmentation threshold settings
for the system.
