Why do wireless ports always buffer the frames before sending?

This is because the wireless port is doing CSMA/CA and sends a Request To Send (RTS) before sending any data frame. It then has to receive a Clear To Send (CTS) from the destination device before sending the data frame. Packet Tracer 4.11 is not showing the wireless management frames, so it would show the data frames being buffered without seeing any other frames.
