number of mobile units that are allowed access on the

• aifsn <1-15> – Arbitration Inter Frame Spacing Number
(AIFSN) defines the wait time (in milliSeconds) between
data frames. Derived using AIFSN and the slot-time.
• burst <0-65535> – Transmit-opportunity. Sets an interval
when a particular WMM STA has the right to initiate
transmissions onto the wireless medium.
• cw <0-15> – Contention Window (cw) parameters.
Wireless stations pick a number between 0 and the
minimum contention window to wait before re-trying
transmissions. Stations then double their wait time on a
collision, until it reaches the maximum contention
window.
