Question: In an 802.11 network, there are three stations, A, B, and C. Station C is hidden from A, but can be seen (electronically) by B.

In an 802.11 network, there are three stations, A, B, and C. Station C is hidden from A, but can be seen (electronically) by B. Now assume that station A needs to send data to station B. Since C is hidden from A, the RTS frame cannot reach C. Explain how station C can find out that the channel is locked by A and that it should refrain from transmitting.
