compromise maximum throughput. The optimistic rate algorithm always looks to
achieve highest throughput while sacrificing noise immunity and robustness. The
EWMA algorithm is a hybrid of the two.
Noise Immunity
: options define the robustness of the device to operate in the
presence of noise disturbance:
For Channel Hopping Signals configuration provides robustness against Channel
Hopping Signals.
For 802.11 Traffic Immunity provides robustness against external 802.11 traffic
sources that are from a foreign network.
Normal 802.11 Operation (default option) provides balanced immunity between
both types of interferers (Channel Hopping Signals and external 802.11 traffic).
RTS Threshold
: determines the packet size of a transmission and, through the use of
an access point, helps control traffic flow. The range is 0-2347bytes, or word “off”. The
default value is 2347 which means that RTS is disabled.
RTS/CTS (Request to Send / Clear to Send) is the mechanism used by the 802.11
wireless networking protocol to reduce frame collisions introduced by the hidden
terminal problem. RTS/CTS packet size threshold is 0-2347 octets. If the packet size
the node wants to transmit is larger than the threshold, the RTS/CTS handshake gets
triggered. If the packet size is equal to or less than threshold the data frame gets sent
immediately
Fragmentation Threshold
: specifies the maximum size for a packet before data is
fragmented into multiple packets. The range is 256-2346 bytes, or word “off”. Setting
the Fragmentation Threshold too low may result in poor network performance. Only
minor modifications of this value are recommended while default setting of 2346
should remain in most of the cases.
The use of fragmentation can increase the reliability of frame transmissions. Because
of sending smaller frames, collisions are much less likely to occur. The fragment size
value can typically be set between 256 and 2,048 bytes.
Multicast Rate
: This option allows Multicast packets to be sent in higher than usual
rates.
Client Isolation
: This option allows packets only to be sent from the router to the
CPE. In other words, CPE's on the same network as the AP will not be able to see each
other.
