Even that's not likely to work because of the variations in wireless channels. This is why 802.11 uses CSMA/CA (collision avoidance) instead of the 802.2 CSMA/CD (collision detection). You can do things on wired channels that you can't on wireless ones. The collision avoidance is to do the carrier sensing and combine it with RTS/CTS to help with avoiding collisions. When not using RTS/CTS, you have to rely on higher layers to detect a missing packet and/or out of order packets and request retransmission or just fail to ACK. Fundamentally a very hard problem.
