Abstract: Provided is an apparatus and method for recognizing a location by conversion of a frequency offset, the apparatus including a setting unit to receive, from a terminal, a plurality of signals comprising a first signal and a second signal, and to set a variable corresponding to each of the plurality of signals, a detector to detect a first residual phase of a carrier frequency of the first signal and a second residual phase of a carrier frequency of the second signal using the variables, and a recognizer to recognize a location of the terminal by calculating a difference between the first residual phase and the second residual phase.
