settings for the Radio QoS policy:
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.
Set the current AIFSN value between 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.
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.
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.
settings for the radio QoS policy:
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.
Set the current AIFSN between1-15. 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.
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.
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.
