Apparatus for expanding coverage area of base station

摘要

An apparatus for controlling a global positioning system (GPS) reference signal to be provided to a base station modem is disclosed to expand a coverage area of a base station, which comprises a GPS clock reception block for generating a system clock and a pp2s signal based on a reference time from the GPS; a system clock distribution block for distributing the system clock received from the clock reception block; a clock generation block for receiving the pp2s signal and generating a clock signal as base station synchronous signals for the expansion of the coverage area; a base station modem block with a multiplicity of base station modems, for performing data modulation/demodulation in synchronism with a corresponding clock signal; a CPU for generating a control signal; and a controller for allowing the data to be transmitted to a selected one among the base station modems, in response to the control signal.
