There are three stations in an 802.11 network: A, B, and C. Station C is hidden from A, but B can see it electronically. Assume station A must send data to station B. The RTS frame cannot reach C because it is hidden from A. Explain how station C can learn that A has locked the channel and that it should refrain from transmitting.
