8. Select the Set Default Values button (if needed), to restore all the field values to their
factory defaults. Symbol recommends default settings in most usage scenarios.
9. Click Apply to save any changes to the New QoS Policy or Edit QoS Policy screen to return
to the Quality of Service Configuration screen. Navigating away from the screen without
clicking Apply results in all changes to the screens being lost.
10. Click Cancel to securely exit the New QoS Policy or Edit QoS Policy screen to return to the
Quality of Service Configuration screen.
11. Click Logout within the Quality of Service Configuration screen to securely exit the AP-5131
Symbol Access Point applet. A prompt displays confirming the logout before the applet is
closed.
5.3.2 Setting the WLAN’s Radio Configuration
Each AP-5131 WLAN can have a separate 802.11a or 802.11b/g radio configured and mapped to that
WLAN. The first step is to enable the radio.
One of two possible radio configuration pages are available on the AP-5131 depending on which
model SKU is purchased. If the AP-5131 is a single-radio model, the Radio Configuration screen
enables you to configure the single radio for either 802.11a or 802.11b/g use. The Radio Configuration
screen contains two radio buttons whose selection is mutually exclusive.
CW Max The contention window maximum value is the maximum amount of
time the MU waits before transmitting when there is no other data
traffic on the network. The longer the interval, the lesser likelihood
of collision, but the greater propensity for longer transmit periods.
AIFSN The AIFSN is the minimum interframe space between data packets
transmitted for the selected Access Category. This value should be
set to a smaller increment for higher priority traffic to reduce
packet delay time.
TXOPs Time 32usec The TXOPs Time is the interval the transmitting MU is assigned
for transmitting. The default for Background traffic is 0. The same
TXOPs values should be used for either the AP-5131’s 802.11a or
802.11b/g radio, there is no difference.
TXOPs Time ms TXOP times range from 0.2 ms (background priority) to 3 ms (video
priority) in a 802.11a network, and from 1.2 ms to 6 ms in an
802.11b/g network. The TXOP bursting capability greatly enhances
the efficiency for high data rate traffic such as streaming video
