This protocol was designed under the assumption that all nodes have the same transmission ranges. RTS/CTS frames can cause the exposed terminal problem in which a wireless node that is nearby, but is associated with another access point, overhears the exchange and then is signaled to back off and
198:. Typically, sending RTS/CTS frames does not occur unless the packet size exceeds this threshold. If the packet size that the node wants to transmit is larger than the threshold, the RTS/CTS handshake gets triggered. Otherwise, the data frame gets sent immediately. 179: 213: 242: 86: 58: 65: 39: 233: 72: 105: 54: 43: 79: 207: 32: 262: 154: 130: 8: 126: 195: 246: 237: 256: 230: 125:
