be generated between 0 and this value. If the

frame is not sent, the random backoff value is

doubled until the value reaches the number

defined by CWMax (below). The CWMin value

must be lower than the CWMax value. The

contention window scheme helps to avoid

frame collisions and determine priority of

frame transmission. A shorter window has a

higher probability (priority) of transmission.

CWMax

Maximum Contention Window (milliseconds):

This value is the upper limit to random

backoff value doubling (see above).

AIFSN

Arbitration Inter-Frame Space (milliseconds):

Specifies additional time between when a

channel goes idle and the AP/client sends

data frames. Traffic with a lower AIFSN value

has a higher priority.

TxOP

Transmission Opportunity (milliseconds): The

maximum interval of time an AP/client can

transmit. This makes channel access more

efficiently prioritized. A value of 0 means only

one frame per transmission. A greater value

effects higher priority.
