IEEE 802.11 RTS/CTS Exchange
CSMA/CA can optionally be supplemented by the exchange of a Request to Send (RTS) packet sent by the sender S, and a Clear to Send (CTS) packet sent by the intended receiver R. Thus alerting all nodes within range of the sender, receiver or both, to not transmit for the duration of the main transmission. This is known as the IEEE 802.11 RTS/CTS exchange. Implementation of RTS/CTS helps to partially solve the hidden node problem that is often found in wireless networking.

Famous quotes containing the word exchange:
“My life is superficial, takes no root in the deep world; I ask, When shall I die, and be relieved of the responsibility of seeing a Universe which I do not use? I wish to exchange this flash-of-lightning faith for continuous daylight, this fever-glow for a benign climate.”
—Ralph Waldo Emerson (1803–1882)
