IN-BUILDING WIRELESS COMMUNICATION SERVICE SYSTEM USING TV CABLE NETWORK AND TERMINAL DEVICE FOR THE SAME

An in-building wireless service system using a TV cable network is disclosed. The system according to the present invention comprises: a TV service wire; a femtocell repeater for outputting a mobile communication signal and a Wi-Fi signal; multiple TV cables installed in a building; a wideband divider coupling a TV signal, the mobile communication signal and the Wi-Fi signal for dividing and transmitting with the multiple TV cables; and a terminator connected to the ends of the multiple TV cables respectively for dividing and outputting each signal. According to the present invention, a new wireless service region can be conveniently built with the end of the TV cable as a center wherever in the building the TV cable is installed. Thus, wireless service quality in the building can be drastically improved since the generation of a shadow area or signal attenuation caused by walls is prevented. Further, in-building wireless service system can be built with low costs and more convenient construction by mounting the terminator of a simple structure at each terminator (for example TV socket) of the TV cable and installing the wideband divider at a terminal box.
