Why not CSMA/CD for wireless LAN?

Answer:

The collision at the receiver, if due to a terminal hidden from the sender, would not be sensed by the sender. So, CD won’t work here. In addition, the sender could not sense while transmitting.

What problem does the RTS/CTS mechanism solve for CSMA/CA in wireless LAN?

Answer:

It solves the hidden terminal problem by having the terminals around the receiver keep silent (after receiving the CTS) when the data frame is being received by the receiver.
