Abstract
Provided are a 5G in-building relay system and a 5G in-building relay method for sharing an RF cable to provide a 5G communication service in the building. The 5G in-building relay system includes: a 5G signal providing device for converting RF signals of a 5G into IF signals and providing the IF signals through a pre-built RF cable of the building; an MHU for receiving and transmitting the IF signals; a coupling device for combining the IF signals with radio signals other than the 5G received from an ROU pre-built in the building and providing the combined signals through the RF cable; a distribution device for receiving the combined signals and separating and distributing the IF signals of the 5G from the combined signals; and a DRU for converting the distributed IF signals into millimeter-wave RF signals and wirelessly transmitting the RF signals to a 5G terminal.
