Maximum Transmit Data Rate
—Select the appropriate data rate from the
drop-down list for the data transfer speed running on your network. (802.11b
default: 11 Mbps.) In order to reach all clients, this rate should be set lower
(for example, 1 or 2 Mbps on an 802.11b radio). To isolate clients that are
unable to connect at higher rates, set this value higher.
Maximum Multicast Data Rate—
Select the appropriate maximum
broadcast/multicast data rate for your network. Setting a low multicast data
rate helps to ensure that data can reach all client stations. Setting a high data
rate can improve performance for high-bandwidth multicast applications (for
example, multimedia streaming service).
Beacon Interval (20-1000)
—Sets the beacon signal interval at which beacon
frames are transmitted from the access point. The beacon signals allow
wireless devices to maintain contact with each other. They may also carry
power-management information. The Beacon Interval unit is TU, which
corresponds to 1024 microseconds. (Default: 100 TU)
Data Beacon Rate (DTIM) (1-255)
—Determines how often the beacon
signal contains a delivery traffic indication message(DTIM). This tells client
devices that are in power-saving mode that a packet is waiting for them.
Fragment Length (256-2346) (802.11g and 802.11a only)
—The Fragment
Length can be set between 256 and 2,346. If the packet size is smaller than
the preset fragment size, the packet will not be segmented.
Fragmentation of the PDUs (Package Data Unit) can increase the reliability of
transmissions because it increases the probability of a successful transmission
due to smaller frame size. If there is significant interference present, or
collisions due to high network utilization, try setting the fragment size to send
smaller fragments. This will speed up the retransmission of smaller frames.
However, it is more efficient to set the fragment size larger if very little or no
interference is present because it requires overhead to send multiple frames.
(Default: 2346)
RTS Threshold (0-2347)
—Set the RTS (Request to Send) frame length. You
may configure the access point to initiate an RTS frame sequence always,
never, or only on frames longer than a specified length. If the packet size is
smaller than the preset RTS threshold size, the RTS/CTS mechanism will not
be enabled.
The access point sends RTS frames to a particular receiving station to
negotiate the sending of a data frame. After receiving an RTS frame, the
station sends a CTS (Clear to Send) frame to acknowledge the right of the
sending station to send data frames.
