I was reading a paper titled "IEEE 802.11 Wireles Local Area Networks" by Crow et al., published by in IEEE Communications Magazine and in it the authors state: "The DCF is based on carrier sense multiple access with collision avoidance (CSMA/CD). CSMA/CD (collision detection) is not used because a station is unable to listen to the channel for collisions while transmitting."
Why is this the case? Why can a station not listen to channel for collisions while transmitting?
Is it that they are physically unable to or is that the physical medium available to the station does not provide a sufficiently clear indication of a collision?
Just curious,
