This sets the maximum and minimum values of the contention window.
The contention window is used in the frame collision avoidance
mechanism that is performed in IEEE802.11, and generally, smaller values
in the window result in a higher likelihood that the queue will obtain
sending rights.
AIFSN
The AIFS number controls the period a wireless node has to wait before
it is allowed to transmit its next frame. The units are slots (the window
defined by CWmin and CWmax). A shorter AIFS period means a message
has a higher probability of being transmitted with low latency, which is
important for streaming video and voice data.
TXOP
The transmit opportunity is the period of time that a station can send
frames. Each unit is 32 ms. Longer TXOP periods may increase network
speeds for a device, but may make other devices on the network seem
unresponsive.
