Wireless stations cannot detect collisions (i.e. the whole packets will be transmitted anyway). Basic CSMA/CA operation: 1) Wait for free medium 2) Wait a random time (backoff) 3) Transmit frame 4) If collision, the stations do not notice it

WebSince collisions are difficult to detect in a wireless environment, the Wi-Fi standard uses a backoff-based collision avoidance technique (CSMA/CA) instead of the more familiar Carrier Sense Multiple Access/Collision Detection (CSMA/CD) used in standard Ethernet. WebCSMA/CA is derived from CSMA/CD (Collision Detection), which is the base of Ethernet. The main difference is the collision avoidance: on a wire, the transceiver has the ability to listen while transmitting and so to detect collisions (with a wire all transmissions have approximately the same strength).
