5. Configure the Performance field to set the preamble, thresholds values, data rates and
QoS values for the radio.
Beacon Interval The beacon interval controls the performance of power save
stations. A small interval may make power save stations more
responsive, but it will also cause them to consume more battery
power. A large interval makes power save stations less responsive,
but could increase power savings.
The default is 100. Avoid changing this parameter as it can
adversely affect performance.
DTIM Interval The DTIM interval defines how often broadcast frames are
delivered for each of the four AP-5131 BSSIDs. If a system has an
abundance of broadcast traffic and it needs to be delivered quickly,
Symbol recommends decreasing the DTIM interval for that specific
BSSID. However, decreasing the DTIM interval decreases the
battery life on power save stations. The default is 10 for each
BSSID. Symbol recommends using the default value unless
qualified to understand the performance risks of changing it.
Support Short
Preamble
The preamble is approximately 8 bytes of packet header generated
by the
AP-5131 and attached to the packet prior to transmission
from the 802.11b radio. The preamble length for 802.11b
transmissions is data rate dependant. The short preamble is 50%
shorter than the long preamble. Leave the checkbox unselected if
in a mixed MU/AP environment, as MUs and the
AP-5131 are
required to have the same RF Preamble settings for interoperability.
The default is Disabled. The preamble length for 802.11a and
802.11g transmissions is the same, with no long or short preamble
lengths.
RTS Threshold RTS allows the
AP-5131 to use RTS (Request To Send) on frames
longer than the specified length. The default is 2341bytes.
