Fragmentation Specify a number between 256 and 2,346 to set the
Threshold frame size threshold in bytes
The fragmentation threshold is a way of limiting the
size of packets (frames) transmitted over the network If
a packet exceeds the fragmentation threshold you set,
the fragmentation function is activated and the packet is
sent as multiple 802 11 frames
If the packet being transmitted is equal to or less than
the threshold, fragmentation is not used
Setting the threshold to the largest value (2,346 bytes)
effectively disables fragmentation Fragmentation plays
no role when Aggregation is enabled
Fragmentation involves more overhead both because
of the extra work of dividing up and reassembling of
frames it requires, and because it increases message
traffic on the network However, fragmentation can help
improve network performance and reliability if properly
configured
Sending smaller frames (by using lower fragmentation
threshold) might help with some interference problems;
for example, with microwave ovens
By default, fragmentation is off We recommend not using
fragmentation unless you suspect radio interference The
additional headers applied to each fragment increase
the overhead on the network and can greatly reduce
throughput
Section 3: Configuring the Access Point
RTS Threshold Specify a Request to Send (RTS) Threshold value between
0 and 2347
The RTS threshold indicates the number of octets in
an MPDU, below which an RTS/CTS handshake is not
performed
Changing the RTS threshold can help control traffic flow
through the AP, especially one with a lot of clients If you
specify a low threshold value, RTS packets will be sent
more frequently This will consume more bandwidth
and reduce the throughput of the packet On the other
hand, sending more RTS packets can help the network
recover from interference or collisions which might
occur on a busy network, or on a network experiencing
electromagnetic interference
Maximum Specify the maximum number of stations allowed to
access this AP at any one time
Stations
You can enter a value between 0 and 200
Transmit Power
Enter a percentage value for the transmit power level for
this AP
The default value, which is 100%, can be more cost-
efficient than a lower percentage since it gives the AP a
maximum broadcast range and reduces the number of
APs needed
To increase capacity of the network, place APs closer
together and reduce the value of the transmit power
This helps reduce overlap and interference among APs A
lower transmit power setting can also keep your network
more secure because weaker wireless signals are less
likely to propagate outside of the physical location of
your network
Fixed Multicast Select the multicast traffic transmission rate you want
the AP to support
