Min. Contention Window This parameter is input to the algorithm that determines

the initial random backoff wait time (“window”) for retry

of a transmission.

The value specified here in the Minimum Contention

Window is the upper limit (in milliseconds) of a range

from which the initial random backoff wait time is

determined.

The first random number generated will be a number

between 0 and the number specified here.

If the first random backoff wait time expires before the

data frame is sent, a retry counter is incremented and

the random backoff value (window) is doubled.

Doubling will continue until the size of the random

backoff value reaches the number defined in the

Maximum Contention Window.

For more information, see “Random Backoff and

Minimum / Maximum Contention Windows” in this

manual.

Max. Contention Window The value specified here in the Maximum Contention

Window is the upper limit (in milliseconds) for the

doubling of the random backoff value. This doubling

continues until either the data frame is sent or the

Maximum Contention Window size is reached.

Once the Maximum Contention Window size is reached,

retries will continue until a maximum number of retries

allowed is reached.

For more information, see “Random Backoff and

Minimum / Maximum Contention Windows” in this

manual.

Max. Burst Length This value specifies (in milliseconds) the Maximum

Burst Length allowed for packet bursts on the wireless

network. A packet burst is a collection of multiple

frames transmitted without header information. The

decreased overhead results in higher throughput and

better performance.

For more information, see “Packet Bursting for Better

Performance” in this manual.
