摘要：Provided are a method, apparatus, and medium for measuring a distance using aradio frequency (RF) signal. The method of measuring a distance includes setting thetransmitter power of an RF signal of a signal generating module to a minimum so as to

measure the longest distance when no obstacle exists, measuring a distance between thesignal generating module and a fixed module using the RF signal whose transmitterpower is set to the minimum, if the measured distance between the signal generatingmodule and the fixed module is available, determining that no obstacle exists

therebetween, and if the measured distance is not available, determining that an obstacleexists therebetween, and determining the distance according to the result of thedetermination of existence of an obstacle.
