Abstract:
A repeating apparatus comprising:a mother station within a base station; and at least one first and second child stations, wherein the mother station mixes a data signal from a mobile switching center to generate an intermediate frequency signal to transfer to a unused telephone line and converts the intermediate frequency signal transferred through the telephone line to a baseband signal to transfer to the mobile switching center, depending on a synchronization signal generated by a synchronization signal generating means in the base station, and the intermediate frequency signal is transferred between the mother station and the at least one first child station through the unused telephone line, wherein the mother station mixes the data signal from the mobile switching center to generate the immediate frequency signal to transfer through a dedicated line network and converts the intermediate frequency signal transferred through the dedicated line network to the baseband signal to transfer to the mobile switching center, depending on the synchronization signal generated by the synchronization signal generating means in the base station, and the intermediate frequency signal is modulated to transfer between the mother station and the at least one second child station through the dedicated line network, wherein the mother station includes: a controlling means for composting the data signal from the mobile switching center with a code division multiple access technique to generate the intermediate frequency signal to transfer through the dedicated line network, converting the intermediate frequency signal transferred through the dedicated line network to the baseband signal and demodulating the baseband signal with the code division multiple access technique for each channel to transfer to the mobile switching center; a frequency converting means for converting the frequency of the intermediate frequency signal to a lower frequency; a signal transferring means for transferring the intermediate frequency signal converted by the frequency converting means to the controlling means; and a signal distributing means for distributing the intermediate frequency signal transferred via the signal transferring means to transfer through the unused telephone line and the dedicated line network and distributing the intermediate frequency signal received through the phone line and the dedicated line network to transfer to the signal transferring means, wherein a signal generated at the base station is transferred by using low frequency bandwidth of the telephone line and signal generated to the first and the second child stations are transferred by using high frequency bandwidth of the telephone line.
