Exposed Station Problem
• Station B is transmitting to station A
• Station C wanting to transmit to station D, would
do the following
– Sense the channel, and “falsely” determine that the
channel is busy. It would then delay transmission till
the channel is sensed idle.
• Had C transmitted, collision could possibly
happened for A, but not for D.
