=== Carrier-sense multiple access with collision avoidance === {{Main|CSMA/CA}} In [[CSMA/CA]] collision avoidance is used to improve the performance of CSMA. If the transmission medium is sensed busy before transmission, then the transmission is deferred for a random interval. This random interval reduces the likelihood that two or more nodes waiting to transmit will simultaneously begin transmission upon termination of the detected transmission, thus reducing the incidence of collision. CSMA/CA is used by [[Wi-Fi]].
