Abstract: Provided are an apparatus and method for measuring an indoor position of a terminal and providing the terminal with path guidance on the basis of a femtocell. The apparatus for measuring an indoor position of a terminal on the basis of a femtocell includes a femtocell base station including a plurality of sensor transmitters respectively transmitting sensor signals for locating the terminal so that the terminal receives the sensor signals and a sensor controller controlling operation of the sensor transmitters, and the terminal configured to receive the sensor signals from the plurality of sensor transmitters, find which sensor transmitters the sensor signals have been transmitted from, and calculate distances between the sensor transmitters having transmitted the sensor signals and the terminal.
