6. Set the following Voice Access settings for the radio QoS policy:
7. Set the following Normal (Best Effort) Access settings for the radio QoS policy:
8. Set the following Video Access settings for the radio QoS policy:
Transmit Ops Use the slider to set the maximum duration a device can transmit after obtaining a
transmit opportunity. When resources are shared between a
Voice over IP (VoIP) call and
a low priority file transfer, bandwidth is normally exploited by the file transfer, thus
reducing call quality or even causing the call to disconnect. With voice QoS, a VoIP call (a
real-time session), receives priority, maintaining a high level of voice quality. For higher-
priority traffic categories (like voice), the Transmit Ops value should be set to a low
number. The default value is 47.
AIFSN Set the current AIFSN value from 1 - 15. Higher-priority traffic voice categories should
have lower AIFSNs than lower-priority traffic categories. This will cause lower-priority
traffic to wait longer before attempting access. The default value is 1.
ECW Min The ECW Min is combined with the ECW Max to create a contention value in the form of
a numerical range. From this range, a random number is selected for the back off
mechanism. Lower values are used for higher priority traffic. The available range is from
0 - 15. The default value is 2.
ECW Max The ECW Max is combined with the ECW Min to create a contention value in the form of
a numerical range. From this range, a random number is selected for the back off
mechanism. Lower values are used for higher priority traffic. The available range is from
0 - 15. The default value is 3.
Transmit Ops Use the slider to set the maximum duration a device can transmit after obtaining a
transmit opportunity. For higher-priority traffic categories, this value should be set to a low
number. The default value is 31.
AIFSN Set the current AIFSN from1 - 15. Higher-priority traffic voice categories should have
lower AIFSNs than lower-priority traffic categories. This will cause lower-priority traffic to
wait longer before attempting access. The default value is 3.
ECW Min The ECW Min is combined with the ECW Max to create a contention value in the form of
a numerical range. From this range, a random number is selected for the back off
mechanism. Higher values are used for lower priority traffic (like Normal). The available
range is from 0-15. The default value is 4.
ECW Max The ECW Max is combined with the ECW Min to create a contention value in the form of
a numerical range. From this range, a random number is selected for the back off
mechanism. Higher values are used for lower priority traffic (like Normal). The available
range is from 0-15. The default value is 6.
Transmit Ops Use the spinner control to set the maximum duration a radio can transmit after obtaining
a transmit opportunity. For higher-priority traffic categories (like video), this value should
be set to a low number. The default value is 94.
AIFSN Set the current AIFSN from 1 - 15. Higher-priority traffic video categories should have
lower AIFSNs than lower-priority traffic categories. This will cause lower-priority traffic to
wait longer before attempting access. The default value is 1.
