Web0. I don´t think it is possible. CSMA/CA is used where the medium is common to all the devices in tx and rx (like Wifi), that´s why it is half duplex and need to avoid collisions. In the beginning there was a ring network using a coaxial cable and "T" connectors, so collision avoidance and half duplex made sense. WebApr 9, 2024 · The Three Types of CSMA.

WebCSMA/CA (Carrier Sense Multiple Access/Collision Avoidance) is a protocol for carrier transmission in 802.11 networks. Unlike CSMA/CD (Carrier Sense Multiple Access/Collision Detect) which deals with transmissions after a collision has occurred, CSMA/CA acts to prevent collisions before they happen.
