摘要： Disclosed are a base station and a mobile terminal for location detection, and a location detecting method. The base station in which a plurality of antennas having RF modules are installed transmits a signal including location information of each of the antennas to the mobile terminal. The mobile terminal carries out location detection by selectively using location information received from a GPS receiver or location information received from a DSRC transceiver. The base station and mobile terminal for location detection can perform location detection with high accuracy using the existing DSRC service. Thus, the base station and mobile terminal can carry out location detection having an error of approximately 10 m in downtown areas or buildings.
