priority, and hence the more capacity share for a given traffic condition.However, the probability of collisions increases when operating with smaller CWmin. These parameters can be used in order to differentiate the channel access among different priority traffic.
EDCA STA Parameters:
Each station maintains a Contention Window (CW), which is used to select the random back off counter.The BC is determined as a random integer drawn from a uniform distribution over the interval (0, CW).The CW size is initially assigned CWmin, and increases when a transmission fails, i.e., the transmitted data frame has not been acknowledged.After any unsuccessful transmission attempt, another back off timer is performed, with an upper bound of CWmax.This reduces the collision probability in case there are multiple stations attempting to access the channel.
CW min: should be smaller for
CW max: should be smaller for
AIFSN: should be smaller for
TXOPLimit: These will allow multiple MAC frames consecutively as long as the whole transmission time does not exceed the TXOP limit.So keep it larger for
ACM: Admission Mandatory; could be turned on to mandatory execution of the contention control.
Connection Control You can restrict certain wireless clients from accessing the router by specifying their MAC address and enabling access restriction.
