IN-HOUSE WIRED/WIRELESS COMMUNICATION AND DATA COMMUNICATION INTEGRATED SERVICE SYSTEM AND METHOD, ESPECIALLY CONCERNED WITH INTEGRATING AND PROVIDING DATA COMMUNICATION AND DIGITAL WIRELESS COMMUNICATION IN A BUILDING

摘要

PURPOSE: An in-house wired/wireless communication and data communication integrated service system and method is provided to integrate a generic wire telephone service, a wireless communication service, and a PC data communication service into one in a building. CONSTITUTION: A generic wire telephone signal and a PC data communication signal are compounded to an xDSL(20) from a central office(10), and they are transmitted to a building through an optical line or an associated wire transmission line. An RF analog signal, generated from a base station(180), is received through an optical line(200) and an RF repeater(190), installed in the building, and the received signal is downconverted into an IF frequency band through a DNC(Down Converter)(170). The IF analog signal is converted into a digital signal by an ADC(160). At this moment, a data line combiner(30) executes line compounding for the wire telephone signal and the PC data communication signal together with the digital signal. Among the 4 lines installed in the building, two lines are used for telephone and PC data communication, the other lines are used for digital wireless communication.
