WebCSMA/CD vs. CSMA/CA (2) CSMA/CA (Collision Avoidance) is the MAC method used in a wireless LAN. 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 WebFounded in 1968, CSMA is dedicated to making the arts and arts education accessible to all, regardless of age, skill level, background or financial means.

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).
