Round Trip Time measurements in 802.11mc are used to estimate how far a client is from an access point by timing how long a signal takes to travel to the AP and back. This time-of-flight data lets the system compute distance, enabling accurate indoor positioning as the device and AP exchange precise timestamps. This is different from measuring channel utilization, which looks at how busy the radio channel is, or from authentication time and beamforming capability, which relate to security handshake timing and directional signal strength, respectively.
