It is used in Distributed … WebRTS/CTS is an additional method to implement virtual carrier sensing in carrier sense multiple access with collision avoidance (CSMA/CA). By default, 802.11 relies on physical carrier sensing only, which is known to suffer from the hidden node problem . The RTS/CTS packet size threshold is 0–2347 octets. Typically, sending RTS/CTS frames does ...
