Dual-Band Wireless A + G Access Point
Frame Burst Mode. Enabling this option should provide your network with greater performance, depending on
the manufacturer of your wireless products. If you are not sure how to use this option, keep the default, Enabled.
Beacon Interval. The default value is 100. The Beacon Interval value indicates the frequency interval of the
beacon. A beacon is a packet broadcast by the Access Point to synchronize the wireless network.
DTIM Interval. This value indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is
a countdown field informing clients of the next window for listening to broadcast and multicast messages. When
the Access Point has buffered broadcast or multicast messages for associated clients, it sends the next DTIM
with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast
messages. The default value is 1.
Fragmentation Threshold. This value specifies the maximum size for a packet before data is fragmented into
multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation
Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor
reduction of the default value is recommended. In most cases, it should remain at its default value of 2346.
RTS Threshold. Should you encounter inconsistent data flow, only minor reduction of the default value, 2347, is
recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will
not be enabled. The Access Point sends Request to Send (RTS) frames to a particular receiving station and
negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send
(CTS) frame to acknowledge the right to begin transmission. The RTS Threshold value should remain at its default
value of 2347.
