DVG-G5402SP User's Manual
RTS Threshold: RTS Threshold is a mechanism to implement in collision avoidance. In a large wireless
network, two stations do not hear each other but can hear wireless access point. When the two send data
to Access Point at the same time, it may result in data collision and a loss of messages for both wireless
stations. In most case, keeping the default value=2347 is recommended.
Beacon Interval: The default value is 100. The Beacon Interval indicates the frequency interval of target
beacon transmission time which can be found in a packet body. The VoIP Router transmits the beacon
packet to help a wireless client to identify the existence of nearby access point. If the beacon intervals are
too long, it would be hard to access the network. If the beacon intervals are too short, the resources would
be wasted.
Data Rate: IEEE802.11b supports Auto, 1, 2, 5.5, 11 Mbps signaling rate. IEEE802.11g supports Auto, 6, 9,
12, 18, 24, 36, 48, 54 Mbps signaling rate. The data rate will change automatically to get better throughput
depending on range and environment of the wireless network.
Preamble Type: Preamble Type defines the length of the preamble which sends out with a packet format.
Specify an appropriate preamble type for your network, if you do not know which one to select, keeping the
default setting Long Preamble is recommended.
Broadcast SSID: Disable the SSID broadcast. This is to prevent users from seeing your wireless network.
802.11g Protection: In 802.11b/g Mixed mode, it can be used for protection mechanism. The 802.11g
OFDM traffic can keep the connection stable and avoid 802.11b interference. But that might cause the poor
throughput.
RF Output Power: You can adjust the percentage of power 100, 50, 25, 10, 5 of your VoIP Router to
change the coverage of wireless network. Keep the default value, 100% to reach full range.
Turbo Mode: The AP would identify the wireless station's chipset to improve the performance.
