TXOP = Length of TXOP 

CWmin
Input to the algorithm that specifies the initial random back off wait time 
(window as known) for retry transmission. This value is the upper limit in milli 
seconds of a range from which initial random back off wait time is determined. 

CWmax
This value is the upper limit in milli seconds for the doubling random back off 
value. This doubling continues until either the data frames are sent or the Max 
Contention Window is reached. 

AIFs
The Arbitration Inter-Frame Spacing specifies a wait time for data frames. 

TXOP 
This is an interval of time when an WMM station or client has the right to initiate 
transmissions onto the wireless medium. 

In this section two possible specific wireless topologies are described, based on 
MicroRed’s operational modes. In the first section two ways of setting a point-to-
point link are described. In the second section a specific topology concerning 
MicroRed Repeater functionality is described. 

There are two basic topology scenarios. You can create a Point-to-Point link 
using either scenario. 

WDS to WDS Scenario 
A point-to-point link can be created by configuring two MicroRed nodes as WDS 
access points.
