Wireless Settings 59priority, and hence the more capacity share for a given trafficcondition.However, the probability of collisions increases when operatingwith smaller CWmin. These parameters can be used in order todifferentiate the channel access among different priority traffic.EDCA STA Parameters:Each station maintains a Contention Window (CW), which is used toselect the random back off counter.The BC is determined as a randominteger drawn from a uniform distribution over the interval (0, CW).TheCW size is initially assigned CWmin, and increases when a transmissionfails, i.e., the transmitted data frame has not been acknowledged.Afterany unsuccessful transmission attempt, another back off timer isperformed, with an upper bound of CWmax.This reduces the collisionprobability in case there are multiple stations attempting to access thechannel.CW min: should be smaller for delay-sensitive dataCW max: should be smaller for delay-sensitive dataAIFSN: should be smaller for delay-sensitive dataTXOPLimit: These will allow multiple MAC frames consecutively aslong as the whole transmission time does not exceed the TXOP limit.Sokeep it larger for delay-sensitive data.ACM: Admission Mandatory; could be turned on to mandatoryexecution of the contention control.Connection Control You can restrict certain wireless clients from accessing the router byspecifying their MAC address and enabling access restriction.
