aifsn <1-15>

Configures AIFSN (Arbitrary Inter-Frame Space Number) as the wait time between data frames derived from the AIFSN and slot time

• background – Sets the current AIFSN for low (background) traffic. The default is 7.

• best-effort – Sets the current AIFSN for normal (best-effort) traffic. The default is 3.

• video – Set the current AIFSN for video traffic. Higher-priority traffic video categories should have lower AIFSNs than lower-priority traffic categories. This causes lower-priority traffic to wait longer before attempting access. The default is 1.

• voice – Sets the current AIFSN for voice traffic. Higher-priority traffic voice categories should have lower AIFSNs than lower-priority traffic categories. This causes lower-priority traffic to wait longer before attempting access. The default is 1.

The following keyword is common to all of the above traffic types:

• <1-15> – Sets a value from 1 - 15

cw-max <0-15>

Clients pick a number between 0 and the min contention window to wait before retransmission. Clients then double their wait time on a collision, until it reaches the maximum contention window.

• background – Sets CW Max for low (background) traffic. The default is 10.
• best-effort – Sets CW Max for normal (best effort) traffic. The default is 6.
• voice – Sets CW Max for voice traffic. The default is 3.
• video – Sets CW Max for video traffic. The default is 4

The following keyword is common to all of the above traffic types:

• <0-15> – ECW: the contention window. The actual value used is (2^ECW - 1).

Lower values are used for higher priority traffic (like video and voice) and higher values are used for lower priority traffic (like background and best-effort).

cw-min <0-15>

Clients select a number between 0 and the min contention window to wait before retransmission. Clients then double their wait time on a collision, until it reaches the maximum contention window.

• background – Sets CW Min for low (background) traffic. The default is 4.

• best-effort – Sets CW Min for normal (best effort) traffic. The default is 4.

• voice – Sets CW Min for voice traffic. The default is 2.

• video – Sets CW Min for video traffic. The default is 3.

The following keyword is common to all of the above traffic types:

• <0-15> – ECW: the contention window. The actual value used is (2^ECW - 1).

Lower values are used for higher priority traffic (like video and voice) and higher values are used for lower priority traffic (like background and best-effort).

txop-limit <0-65535>

Set the interval, in microseconds, during which a particular client has the right to initiate transmissions

• background – Sets TXOP for low (background) traffic. The default is 0.

• best-effort – Sets TXOP for normal (best effort) traffic. The default is 4.

• voice – Sets TXOP for voice traffic. The default is 47.

• video – Sets TXOP for video traffic. The default is 94.

The following keyword is common to all of the above traffic types:

• <0-65535> – Specify a value from 0 - 65535 to configure the transmit opportunity limit in 32 microsecond units.

Lower values are used for higher priority traffic (like video and voice) and higher values are used for lower priority traffic (like background and best-effort).
