PURPOSE: A device for measuring delay time between repeaters of a mobile communication system and a method therefor are provided to calculate a link distance or delay time between a base station and a remote device or between a donor device and the remote device when using repeaters, thereby optimizing cells. CONSTITUTION: The first FPGA(Field Programmable Gate Array)(212) is realized with a program logic, through which the first FPGA(212) generates a test pulse signal for measuring communication delay time to deliver the test pulse signal, and counts time for receiving a response pulse signal. The second FPGA(226) receives the test pulse signal from the first FPGA(212), generates the response pulse signal, and delivers the generated response pulse signal. The first and second communication processors(214,228) perform communication control functions for a mobile communication service. The first and second digital switches(216,224) switch communication transmission paths between the first(212) or the second FPGA(226) and the first and second communication processors(214,228). The first and second communication modems(218,222) transceive data.
