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.
RTS Threshold :
TRTS Threshold is in the range of
1~2347
byte. The default is
2347
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 :
the process of listening to Internet Group Management Protocol (IGMP)
network traffic. The feature allows a network switch to listen in on the IGMP conversation
between hosts and routers. By listening to these conversations the switch maintains a
map of which links need which IP multicast streams. Multicasts may be filtered from the
links which do not need them and thus controls which ports receive specific multicast
traffic.
Greenfield :
In wireless WLAN technology, greenfield mode is a feature of major
components of the 802.11n specification. The greenfield mode feature is designed to
improve efficiency by eliminating support for 802.11b/g devices in an all draft-n network.
In greenfield mode the network can be set to ignore all earlier standards.
Signal LED Thresholds :
This function can setting RSSI number(1~99) to control signals
LED’s, The DT-300N system will calculate for RSSI number and total of three LED’s
indicator, If LED's whole bright indicate signal is the strong.
The function only support Client Bridge and WISP modes
