Abstract:
(EN) The present invention relates to a next generation in-building relay system and method for providing a 5G service using a wideband in superhigh frequencies of 30-300 GHz in a building by sharing an optical cable already wired in the building. In addition, according to the present invention, provided are a next generation in-building relay system and a method therefor, the system comprising: a 5G signal providing unit for down-converting a millimeter wave radio frequency signal into an intermediate frequency signal; a 5G main hub unit for converting the intermediate frequency signal down-converted in the 5G signal providing unit into a radio over fiber (RoF) signal, which is an analog optical signal, and transmitting the RoF signal; an optical coupling unit, which couples a digital optical signal outputted from a main hub unit and the analog optical signal outputted from the 5G main hub unit and transmits the coupled signal to an optical cable; and an optical distribution unit, which separates the digital optical signal outputted from the main hub unit and the analog optical signal outputted from the 5G main hub unit, both signal being transmitted from the optical coupling unit, so as to transmit, to a remote optical relay unit, the digital optical signal outputted from the main hub unit and transmit, to distribution remote units, the analog optical signal outputted from the 5G main hub unit.
