The RTS packet is slightly larger than the CTS since it contains … The RTS, CTS and ACK frame headers all contain a frame control field (two bytes of metadata flags), duration field, a field for the receiver MAC address, and a frame check sequence. Additionally, an RTS frame contains the transmitter's MAC address. This protocol was designed under the assumption that all nodes have the same transmission ranges, and does not solve the hidden terminal problem.
