Abstract:
1. A base station for detecting a location of an outdoor mobile terminal, comprising: a location information generator for generating location information of each of a plurality of antennas arranged at specific intervals; a central processing unit for processing data transmitted and received between the base station and the mobile terminal, and generating a periodic beacon signal for transmission to the mobile terminal; a location information processor for loading the location information of each of the antennas in a header of the beacon signal from the central processing unit, and transmitting the beacon signal with the header to a corresponding antenna, the location information of the corresponding antenna indicating an approximate location of the mobile terminal; a modulating/demodulating unit for converting data transmitted and received between the central processing unit and the antennas into an analog or digital signal; and a plurality of multiplexers, with each multiplexer associated with one of the antennas and multiplexing at an input end of each multiplexer between the beacon signal and the converted data, the plurality of multiplexers simultaneously outputting the beacon signal, including the header, to the antennas, wherein the beacon signal is transmitted from the location information processor and the converted data is transmitted from the modulating/demodulating unit.
