WebMay 18, 2024 · CSMA/CA is a medium access control for IEEE 802.11 wireless local area network. Carrier sense means that a node on the network can detect what is going on in … WebJul 2, 2008 · When a station wants to transmit, it picks up a random number, the backoff timer, from which it counts down before deciding to send. Say you pick up 16. You count down from there (the speed of the countdown depends on if you use 802.11b, g or a). Every time it decrements the counter, it listens to the air.
