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. chittering animite mount
